A) have formed and broken up several times
B) occurred only during the Phanerozoic Eon
C) occurred only during the Archean Eon
D) are an exclusively Cenozoic development

Answers

Answer 1

As an example of a cyclical global change, supercontinents Option A) have formed and broken up several times. in the Earth's history.

Supercontinents are large landmasses that consist of multiple continents fused together. Throughout Earth's history, the formation and breakup of supercontinents have occurred in a cyclical pattern. The most well-known supercontinent is Pangaea, which existed approximately 300 million years ago during the late Paleozoic and early Mesozoic eras.

The process of supercontinent formation and breakup is known as the supercontinent cycle. It involves the assembly of continents into a single landmass, followed by their fragmentation and dispersal. This cycle is driven by the movement of tectonic plates on Earth's surface.

Supercontinents typically form when continental plates collide and converge, causing continents to merge together. Over time, these supercontinents start to break apart due to the forces of plate tectonics. The continents then drift apart, leading to the formation of new oceans and the re-establishment of separate landmasses.

In conclusion, supercontinents have formed and broken up several times throughout Earth's history as part of a cyclical global change known as the supercontinent cycle. This process has played a crucial role in shaping our planet's geology and has had a profound impact on its environment and life forms. Therefore, the correct option is A.

Which of the following describes the progression of rock types through increasing metamorphic grade from left to right?
shale -> slate-> phyllite-> schist

Answers

The correct progression of rock types through increasing metamorphic grade from left to right is shale -> slate -> phyllite -> schist. Here option A is the correct answer.

Metamorphic rocks form when pre-existing rocks undergo changes in temperature, pressure, and chemical composition. The progression of rock types reflects the increasing intensity of these metamorphic processes.

Shale is the starting point, which is a sedimentary rock composed of fine-grained clay minerals. With increased metamorphic conditions, shale undergoes recrystallization and compaction, transforming into slate. Slate is characterized by its fine-grained texture and excellent foliation, resulting from the alignment of minerals.

As the metamorphic grade continues to increase, slate further recrystallizes and develops a shiny appearance, forming phyllite. Phyllite exhibits a higher degree of metamorphism compared to slate.

eroded material that are transported are finally dropped off in a process called

Answers

Deposition is the final stage in the process of erosion, where eroded materials are dropped off or settled in a new location. Here option B is the correct answer.

Erosion occurs when natural forces such as water, wind, or ice remove and transport weathered materials from their original location. During erosion, rocks, soil, and other materials are broken down into smaller pieces and then carried away by the agents of erosion.

As these eroded materials are transported by wind, water currents, or glacial movement, they eventually lose their energy and settle down. This settling process is known as deposition. When the transporting agent loses its ability to carry the sediments, it releases them, allowing them to accumulate in new locations.

Deposition can occur in various environments, such as river deltas, beaches, floodplains, and the ocean floor. The specific characteristics of the deposition site, such as the speed of water or wind, will determine the size and type of sediment that is deposited. Heavier particles, such as sand and gravel, are usually dropped off closer to the source of erosion, while finer particles, like silt and clay, may be carried further before being deposited.

the composition of a composite cone or stratovolcano makes its viscosity ________.

Answers

The composition of a composite cone or stratovolcano typically makes its viscosity relatively high or more viscous compared to other types of volcanoes.

Composite cones or stratovolcanoes are characterized by their steep-sided, symmetrical cones built up by alternating layers of lava flows, volcanic ash, and other pyroclastic materials. The composition of these materials plays a significant role in determining the viscosity of the magma erupted from the volcano.

Stratovolcanoes often form from intermediate to felsic magma, which contains higher amounts of silica and other viscous materials. Silica-rich magma has a higher viscosity due to the stronger bonding between its components, making it thicker and more resistant to flow. As a result, when stratovolcanoes erupt, the magma tends to be more viscous, meaning it is thicker and flows less easily.

The higher viscosity of the magma in composite cones contributes to their explosive nature. The gas trapped within the viscous magma has difficulty escaping, leading to the build-up of pressure. This pressure can result in explosive eruptions characterized by the eruption of ash, gas, and pyroclastic materials.

It's important to note that while the composition of a composite cone influences its viscosity, there can be variations within this volcano type. The specific composition of the magma, including the presence of other minerals and volatile elements, can further affect the viscosity and eruptive behavior of individual stratovolcanoes.

There are 10 history books in a bookcase. When the number of books increases by x percent, the new number of history books is 24. What is the value of x

Answers

The value of x is 140. This means the number of history books increased by 140%.

Let's solve the problem step by step:

Let's assume the initial number of history books in the bookcase is represented by "10."

When the number of books increases by x percent, the new number of history books becomes "10 + (x/100) * 10."

According to the problem, the new number of history books is 24, so we can set up the equation:

10 + (x/100) * 10 = 24

To find the value of x, we can solve this equation:

10 + (x/100) * 10 = 24

10 + 10x/100 = 24

10 + 0.1x = 24

0.1x = 14

x = 14 / 0.1

x = 140

how long does postglacial rebound take after continental ice sheets melt?

Answers

The timescale for postglacial rebound is typically on the order of thousands to tens of thousands of years. However, it is important to note that the process is gradual and occurs over an extended period.

Postglacial rebound, also known as isostatic rebound, refers to the rising of land masses that were previously depressed by the weight of glaciers during the last ice age. The time it takes for postglacial rebound to occur after the melting of continental ice sheets depends on several factors, including the size and thickness of the ice sheets and the location of the land masses.

Generally, it takes several thousands of years for postglacial rebound to occur. The process starts immediately after the melting of the ice sheets, but it is a slow and gradual process that can take up to tens of thousands of years to complete. In some areas, such as the northern parts of North America and Europe, postglacial rebound is still ongoing, and the land is rising at a rate of a few millimeters per year.

It is important to note that postglacial rebound is not a uniform process and can vary from one region to another. Some areas may experience faster rebound rates than others due to differences in geology, tectonic activity, and other factors. Additionally, postglacial rebound can have significant impacts on the environment, including changes in sea levels, changes in river courses, and the formation of new wetlands and lakes.

What factor contributed the most the flooding of new orleans after hurricane katrina?.

Answers

Multiple factors contributed to the flooding of New Orleans after Hurricane Katrina. However, one of the most significant factors was the failure of the city's levee system.

Hurricane Katrina made landfall on August 29, 2005, and brought intense rainfall and storm surge to the Gulf Coast. The storm surge, which refers to the rise in water level caused by a hurricane's winds and low atmospheric pressure, overwhelmed the levee system designed to protect New Orleans from flooding.

The levees in New Orleans were designed to withstand certain storm surge heights, but they were not constructed to withstand the intensity of Hurricane Katrina's storm surge. As a result, several sections of the levee system breached or failed, allowing water to inundate the city.

The failure of the levee system led to catastrophic flooding in many areas of New Orleans, including the Lower Ninth Ward and other neighborhoods. The floodwaters caused widespread devastation, displacement of residents, loss of life, and significant damage to infrastructure.

Other factors that contributed to the flooding included the city's low-lying geographical location below sea level, the subsidence of land, and the erosion of coastal wetlands that act as natural buffers against storm surge.

which of these is a reason that the poles are colder than the equator? group of answer choices greenhouse effect is more significant near the equator increased beam spreading at higher latitudes due to earth being spherical there are more volcanoes near the equator which release heat the poles are further away from the sun than the equator

Answers

The reason the poles are further from the sun than the equator is that they are colder. Here option D is the correct answer.

The primary reason that the poles are colder than the equator is their distance from the sun. The Earth's axis is tilted, causing the sun's rays to strike the poles at a much greater angle compared to the equator.

Due to this oblique angle, the same amount of solar energy is spread over a larger surface area at the poles, resulting in less concentrated heat per unit of area. Additionally, the sunlight has to pass through a larger portion of the atmosphere to reach the poles, which leads to greater absorption and scattering of solar radiation, further reducing the amount of heat reaching the surface.

On the other hand, the equator receives more direct and concentrated sunlight due to its proximity to the sun. The solar energy is spread over a smaller area, allowing for more intense heating. As a result, the equatorial regions experience higher temperatures compared to the poles.

formulate hypothesis of an analysis of weather patterns and data over a longer period in Johannesburg CBD in the year 2009​

Answers

Explanation:

Sure, here are some hypotheses that could be tested by analyzing weather patterns and data over a longer period in Johannesburg CBD in the year 2009:

* The average temperature in Johannesburg CBD has increased over the past 10 years.

* The number of days with rainfall has decreased over the past 10 years.

* The number of days with extreme weather events, such as heat waves and droughts, has increased over the past 10 years.

* The average humidity in Johannesburg CBD has increased over the past 10 years.

* The average wind speed in Johannesburg CBD has decreased over the past 10 years.

These are just a few examples, and there are many other hypotheses that could be tested. By analyzing weather patterns and data over a longer period, we can gain a better understanding of how the climate is changing in Johannesburg CBD and how this is impacting the city and its residents.

Here are some additional details about each hypothesis:

* The average temperature in Johannesburg CBD has increased over the past 10 years. This is supported by data from the South African Weather Service, which shows that the average temperature in Johannesburg has increased by about 1 degree Celsius since 1999.

* The number of days with rainfall has decreased over the past 10 years. This is also supported by data from the South African Weather Service, which shows that the number of days with rainfall in Johannesburg has decreased by about 10 days per year since 1999.

* The number of days with extreme weather events, such as heat waves and droughts, has increased over the past 10 years. This is supported by anecdotal evidence, as well as by data from the South African Weather Service, which shows that there have been more heat waves and droughts in Johannesburg in recent years than in the past.

* The average humidity in Johannesburg CBD has increased over the past 10 years. This is supported by data from the South African Weather Service, which shows that the average humidity in Johannesburg has increased by about 5% since 1999.

* The average wind speed in Johannesburg CBD has decreased over the past 10 years. This is supported by data from the South African Weather Service, which shows that the average wind speed in Johannesburg has decreased by about 10% since 1999.

These changes in weather patterns are likely due to climate change. Climate change is caused by the release of greenhouse gases into the atmosphere, which trap heat and cause the Earth's temperature to rise. The effects of climate change are already being felt around the world, and they are expected to become more severe in the future.

The changes in weather patterns in Johannesburg CBD are having a number of impacts on the city and its residents. These impacts include:

* Increased risk of heat waves and droughts, which can lead to health problems, crop failures, and water shortages.

* Increased risk of flooding, which can damage property and infrastructure.

* Increased risk of wildfires, which can destroy homes and businesses.

* Changes in plant and animal life, as some species are able to adapt to the changing climate while others are not.

The city of Johannesburg is taking steps to adapt to the impacts of climate change. These steps include:

* Investing in renewable energy sources, such as solar and wind power.

* Developing more efficient water and energy use technologies.

* Planting trees and other vegetation to help cool the city.

* Educating residents about climate change and how they can help to mitigate its effects.

The city of Johannesburg is also working with other cities around the world to address the issue of climate change. This includes participating in international agreements to reduce greenhouse gas emissions and sharing information and best practices.

Climate change is a serious challenge, but it is one that can be overcome. By working together, we can build a more sustainable future for Johannesburg and for the world.
