Answer 1

Answer:

Density

Explanation: Density: An unusual characteristic of water is that, unlike most solids, ice is less dense than liquid water. For this reason, ice cubes float in a glass of water rather than sink to the bottom of the glass.

slab pull refers to . multiple choice question. subducting lithosphere transform boundaries of lithospheric plates divergent boundaries of lithospheric plates subducting mantle

Answers

Slab pull is a geophysical phenomenon whereby the cooling and subsequent densification of a subducting tectonic plate impose downward pressure along the rest of the plate.

What is slab pull?The process that occurs along a subduction zone when a dense oceanic plate falls beneath a buoyant plate, bringing the remaining plates behind it. Subduction is the process through which a tectonic plate descends into the mantle. When an oceanic plate subducts into the underlying mantle, slab pull happens. Subduction zones are just one form of convergent border where two tectonic plates are clashing. A crustal plate cools and gets denser as it advances away from an oceanic ridge. As a result, it subducts into a zone beneath the continental crust. The rest of the plate is also dragged downward by the weight of the sinking, cooling plate due to a strong pulling action.

what is define foliated rocks?

Answers

Foliated rocks are a type of metamorphic rock that is characterized by having visible layers or bands of minerals, which are usually aligned parallel to each other.

This texture is the result of the rock being subjected to intense heat and pressure, causing the minerals within it to re-crystallize and become arranged in a specific orientation.

The alignment of the minerals in foliated rocks can give them a distinct texture and appearance, which can be used to identify and classify them.

Some common types of foliated rocks include slate, schist, and gneiss. Foliated rocks can be found in a variety of settings, including mountain ranges, deep within the earth's crust, and along fault lines. They are important in geology as they provide clues to the history and processes of the earth's crust.

What depends most on water stored in Lake Nasser?

Answers

Water from Lake Nasser is mostly used for perennial irrigation.

What resources does the Nile river provide?

The Nile is only a few kilometers away from where 95% of Egyptians reside today. To irrigate farmland and sustain towns, canals transport water from the Nile. Agriculture and fishing are supported by the Nile. Throughout the ages, the Nile has also been a crucial conduit for travel.

Temperatures will keep rising as a result of climate change. This results in more evaporation of the water that has been stored. Now, the Aswan Dam-abutting Lake Nasser loses 12% of its volume each year to evaporation, or 16 billion cubic meters of water yearly.

A perennial irrigation system ensures that crops receive continuous and consistent water delivery throughout the crop period according to the needs of the crop. This technique uses a weir or a reservoir as the starting point for a canal distribution system that supplies water to the crops.

Based on what you know about light and matter interactions, select all of the correct statements from the following list. a Absorption spectra have bright lines. Low-density hot gases produce emission spectra. Emission spectra have dark lines. The size of an electron's orbit depends on its energy Atoms absorb energy by emisting photons. a Electrons will move to higher orbits when an atom absorbs enough energy a Hot solids emit continuous spectra.

Answers

About light and matter interactions, the correct statements from the following list are:

b) Low-density hot gases produce emission spectra.

d) The size of an electron's orbit depends on its energy

f) Electrons will move to higher orbits when an atom absorbs enough energy

So, the option b,d and f are the correct option.

Low-density hot gases produce emission spectra: When a low-density hot gas is heated to a high temperature, its electrons become excited and emit light at specific wavelengths. This produces an emission spectrum, which is a characteristic pattern of light corresponding to the different energies of the electrons in the gas.

The size of an electron's orbit depends on its energy: The size of an electron's orbit is determined by its energy. Electrons with higher energy occupy larger orbits and those with lower energy occupy smaller orbits.

Electrons will move to higher orbits when an atom absorbs enough energy: When an atom absorbs enough energy, its electrons can be excited to move to higher orbits. This can happen through the absorption of light or other forms of energy. The electrons will then emit light when they return to their original orbit.

Magnetic stripes on the seafloor are oriented parallel and symmetric to the seafloor and also oriented concerning mid-ocean ridges. Hence, option A is appropriate.

What is the meaning of mid-ocean ridges?

A system of seafloor mountains called a mid-ocean ridge is the result of plate tectonics. It normally rises 2,000 meters above the lowest part of an ocean basin and has a depth of roughly 2,600 meters. This feature represents the location of a divergent plate boundary where seafloor spreading occurs.

Since they are found along the kind of subduction zone where the new ocean bottom is formed as the plates grow apart, mid-ocean ridges are significant geologically.

No stars are expected with masses greater than 150 times our Sun because B) they would generate so much power that they would blow themselves apart.

Stars with masses greater than 150 times our Sun are known as very massive stars, and their powerful radiation can cause them to lose mass at an extremely rapid rate. This means that they have a relatively short lifespan, and they can explode as supernovae or collapse directly into black holes. Therefore, they are not expected to exist for very long, and this is why they are difficult to detect.
