Question

Which characteristic would most likely remain constant when a limestone cobble is subjected to extensive abrasion?

Answer 1

Answer:

Composition

Explanation:

Weathering can be simply defined as the break down of rocks that is caused by the agents such as wind, water and ice. One of the process that leads to the weathering of rocks is abrasion, where the rock is scrapped off due to the continuous flow of water, blowing of wind and movement of ice over the surface of the rock. Limestone is a chemical sedimentary rock that is easily disintegrated when rainfall occurs. It dissolves the materials present in the limestone rock, and is considered to be a chemical weathering process.

When this limestone rock is subjected to extensive abrasion, then only the composition of the rock remains constant, and its other properties alters.
