Which of these conditions does not contribute to the weathering of rock on earth's surface?

a. variable temperature
b. exposure to air
c. constant high pressure
d. abundance of water

C. Constant high pressure

Explanation:

Constant high pressure is not a factor that causes weathering on the earth surface.

Temperature, air and water affects how a rock changes through time. They have the capacity to cause physical disintegration and chemical decomposition of rocks.

C. Constant high pressure

Constant high pressure does not contribute to the weathering of rock on Earth's surface.

Explanation:

On the Earth surface, fragmentation of rocks is described as weathering. Followed by weathering the tiny pieces of rocks which breaks down are transported by the process of erosion. Exposure to atmosphere, composition of rocks, water, mineral salts, acids, animals, plants, and changes in temperature are all the major factors of weathering.

The most easily weathered rocks are sedimentary rocks, as they are harder and contains calcite. The higher amount of weathering occurs on larger surface area and it doesn't involve in removal of rock material. Types of weathering includes mechanical, chemical and biological.
