The statement that weathering occurs as a result of direct contact with the atmosphere is true. Weathering is a process by which rocks are broken down by direct contact with the atmosphere which is caused by exposure to heat, ice, and elements in the atmosphere. Two type of weathering are: Physical and Chemical weathering.Physical weathering occurs when rocks, soil, or minerals are broken down through mechanical means.Chemical weathering occurs when rocks, soil, or minerals are broken down through reactions with chemicals that are in the air or are biologically introduced.
Answer:
Mesosphere
Explanation:
The mesosphere starts at 31 miles (50 km) and extends to 53 miles (85 km) high. The top of the mesosphere, called the mesopause, is the coldest part of Earth's atmosphere, with temperatures averaging about minus 130 degrees F (minus 90 C).
Precisely 3.2 astronomical units.
The answer is D. Gravity.
Gravity attracts objects to the surface of the Earth. Take a falling brick, for example, the brick has more mass, therefore, there is more attraction between the brick and Gravity. The brick is a solid object and is heavier as well.
Hope this helps! :)
