E) batholiths

Question

Quizplus · Accepted Answer

Clay is a fine-grained sub-surface material that can intensify the process of earthquakes and mass movement. This is because clay has a high water content and is prone to swelling and shrinking with changes in moisture, which can affect the stability of slopes and cause landslides. Additionally, when clay is subjected to stress from tectonic activity, it can become liquefied and lose its ability to support structures or slopes, leading to increased damage and instability.
