What is a common effect of tectonic compression?

• A. Formation of rift valleys
• B. Creation of mid-ocean ridges
• C. Elevation of mountain ranges
• D. Formation of fault lines

Answer: (C)

Tectonic compression refers to the process where tectonic plates converge or collide, leading to a variety of geological impacts. One of the most notable effects of this process is the elevation of mountain ranges. When two continental plates collide, the immense forces involved can cause the crust to buckle and fold, resulting in the uplift of land, which eventually forms mountain ranges.

This process can lead to the creation of complex geological structures, such as folds, thrusts, and faults, all of which contribute to the vertical rise of terrain. Over time, repeated episodes of tectonic compression can significantly increase the height and extent of these mountains.

In contrast, the other choices reflect different geological processes: rift valleys are typically formed in extensional environments where tectonic plates are moving apart; mid-ocean ridges are created at divergent boundaries where plates are separating, allowing magma to rise and solidify; and fault lines are associated with lateral movements of tectonic plates, often due to shear stress rather than pure compression.
