Answer:
We study about the sun because
The sun is a normal star. It is much closer to us than any other star, and by studying the sun, we can therefore learn more about other stars. The better we understand other stars, the more we know about the Milky Way. From there we know more about other galaxies and in the end we learn more about the universe.
Explanation:
How does the Sun help to protect life on Earth?
It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth. Plants need sunlight to grow. Animals, including humans, need plants for food and the oxygen they produce. Without heat from the sun, Earth would freeze.
Answer:
Humans require water for survival, so they tend to settle near areas with access to large amounts of water. Rainfall and water bodies such as rivers and lakes provide humans with clean water for drinking, cleaning, agriculture and recreational activities. Pollution of water supplies and population growth depletes aquifers leading to competition and waterborne diseases, especially in developing countries.
Climate patterns around the world influence human settlements. They live in conditions that favor their lifestyles and alter their clothing and housing in accordance with climate. In addition, extreme weather leads to sparsely populated areas and limit agricultural practices; for example, harsh and cold weather favor plants that can adapt to that environment.
Land formations such as mountains and hills shape transportation routes and networks, while the movement of tectonic plates on the Earth's surface sometimes causes hazards like earthquakes that destroy habitats, displace humans and affect the availability of water.
Fertile soil carries out numerous functions such as supporting life, recycling nutrients, regulating water and providing structural support for buildings. Humans extract minerals and perform recreational activities on the soil. Infertility creates deserts and leads to the migration of settlements.
A balanced ecosystem relates to better agricultural produce and less air pollution. Provision of food, safe water and clean air improves the well-being of living organisms.

The answer to this question is More elastic
A product usually become inelastic if that product does not have any subtitute to fulfill the same function.
In the long run, advancement in technologies will create a way cheaper method in producing energy (such as electric, nuclear, or solar) which will make natural gas become more elastic.
hello there
Explanation:
Weathering is when rock (generally) or material is worn away via the Earth's atmosphere, the sun, water, or other natural elements. This is considered destructive.
Erosion is when water (usually rivers or rain) carries rock away from its original place or recently deposited position. This is considered destructive.
Deposition is when the rock that has been eroded away is deposited into a new place. This is considered contructive.
