Crustal deformation plays a crucial role in building landforms through various tectonic processes. The most relevant response to this process is:
When two tectonic plates start to push into each other they can rise up and build mountains, or sink under and create deep valleys.
This describes how the interactions between tectonic plates—specifically convergent boundaries where plates collide—result in the uplift of mountain ranges or the formation of deep oceanic trenches and valleys due to subduction. The immense pressures and forces involved in these interactions lead to significant changes in the Earth's crust, creating diverse landforms over geological time.
The other options refer to sediment deposition, erosion, and volcanic activity, which are also important geological processes but are not directly about crustal deformation.
