1.what are effect of physical factors on human activity ?

2.Explain three factors that contributed to rapid world population growth after the 1950's?​

Answers

Answer 1
1. Physical factors such as climate, terrain, and access to resources can have a significant impact on human activity. For example, a warm climate may encourage outdoor activities, while a cold climate may lead to more indoor activities. Terrain can also affect human activity, as mountainous regions may limit access to certain areas, while flat terrain may allow for easier travel. Access to resources such as food, water, and shelter can also influence human activity, as people may need to travel to access these resources.

2. Three factors that contributed to rapid world population growth after the 1950's include improved healthcare, increased food production, and increased access to education. Improved healthcare led to a decrease in infant mortality rates and an increase in life expectancy, allowing more people to survive to adulthood. Increased food production allowed for more people to be fed, while increased access to education allowed for more people to gain the skills and knowledge needed to find employment and support their families.
Answer 2

1.    Physical factors can have a significant impact on human activity, both in terms of where people choose to live and work and how they go about their daily lives. Some common physical factors that can affect human activity include:

   Climate: People tend to prefer living in areas with moderate temperatures and adequate rainfall. Extreme heat, cold, or dryness can make it difficult to work or carry out daily activities.

   Topography: The shape and elevation of the land can affect human activity in a number of ways. For example, steep hills or mountainous terrain can make it difficult to build roads and buildings or farm the land.

   Natural disasters: Earthquakes, floods, hurricanes, and other natural disasters can have a major impact on human activity by damaging buildings and infrastructure, disrupting transportation, and causing injury or loss of life.

2.    There were several factors that contributed to rapid world population growth after the 1950s. Three of the most significant include:

   Medical advances: In the mid-20th century, there were significant advances in medical technology and public health, including the development of antibiotics, vaccines, and other treatments that helped reduce mortality rates and improve life expectancy.

   Agricultural advancements: Advances in agricultural technology, including the use of fertilizers, pesticides, and irrigation systems, helped increase crop yields and feed more people.

   Urbanization and industrialization: As countries became more industrialized and urbanized, there were more job opportunities and people began to migrate from rural areas to cities. This shift in population helped contribute to the overall increase in global population.

a fuel's ____ is the total amount of thermal energy released when a specific amount of that fuel burns.

Answers

A fuel's heat of combustion is the total amount of thermal energy released when a specific amount of that fuel burns.

The quantity of heat released when a specific amount of a substance undergoes burning is known as the heat of combustion, also known as the calorific value or the energy value. The term "heat of combustion" is frequently used interchangeably with "calorific value," which is the total amount of energy released after the full combustion of a given mass of a substance in the presence of (enough) oxygen under typical conditions of pressure & temperature.

Why is the Driving Force behind the Oceans Global Conveyor  the Difference in Heat Energy Balance  at different  Earth Latitude?

The reason why the driving force behind the ocean's global conveyor belt is differences in the heat energy balance at different latitudes on Earth is because the conveyor belt is driven by a combination of temperature and salinity gradients in the ocean, which are influenced by the amount of solar energy that reaches different parts of the planet.

Specifically, warm water at the surface of the ocean near the equator flows towards the poles, where it cools and sinks, and then is transported back towards the equator in deeper ocean currents. This process helps to distribute heat energy around the planet and plays a key role in regulating weather and climate.

Explanation:

Consider the following discussion between two students about the cause of the seasons.

Student 1: I get it. So since Earth is tilted, there are times when the northern part of
Earth is closer to the Sun than the southern part. So the north has summer and the south has winter. And then later, the south is tilted toward the Sun and gets closer and has summer.

Student 2: I disagree. Although the tilt does bring one hemisphere closer to the Sun, the difference in distance between the northern half and southern half of Earth is really small compared to how far away Earth is from the Sun.

Do you agree or disagree with either or both of the students? Explain your reasoning.




Please include the explanation and not just which student to agree with. Thanks!

Answers

I agree with Student 1. The cause of the seasons is indeed the tilt of the Earth's axis. As the Earth orbits around the Sun, the northern hemisphere is tilted towards the Sun during the summer, and away from the Sun during the winter. This causes the northern hemisphere to receive more direct sunlight during the summer months, leading to warmer temperatures and longer days. At the same time, the southern hemisphere is tilted away from the Sun during the northern hemisphere's summer, causing it to receive less direct sunlight and leading to cooler temperatures and shorter days.

While it is true that the difference in distance between the northern and southern halves of the Earth is relatively small compared to the distance between the Earth and the Sun, it is the angle of the Sun's rays that is more important in determining the amount of sunlight and heat received by a particular region on Earth. This is because the angle of the Sun's rays affects the amount of atmosphere the sunlight has to pass through, and this can cause the sunlight to be more or less intense, depending on the angle.

In conclusion, the tilt of the Earth's axis is indeed the cause of the seasons, and Student 1 is correct in their understanding of this phenomenon.
