Chemical weathering in bedrock below the land surface often begins along joints and sheeting fractures. True False

TRUE

Explanation:

Chemical weathering usually refers to the process in which the water comprising various chemicals reacts on the rocks and disintegrates them. The chemical weathering process occurs both at and below the surface of the land. At various depths, the rocks are comprised of cracks and fractures, which are filled up with water comprising the chemicals. This water reaching these joints and fractures are percolated from the surface. These chemicals comprising water start reacting with the rocks and eventually expands the cracks and joints.

For example, in the region where there is abundant carbonate rocks, these chemical comprising water (such as acid water) when enters, it reacts with the rocks and dissolves them, and thereby give rise to the formation of caves and sinkholes.

Thus, the above-given statement is true.
