Question

(cs 5) what is glaciation?

glaciation is the process whereby snow has been converted to ice by the force of gravity and pressure.

glaciation is the process by which mountains are formed.

glaciation is the process of melting ice caps due to global warming.

Explanation:

To determine the correct definition of glaciation, we analyze each option:

• The first option: Glaciation involves the transformation of snow into ice under gravity and pressure, which aligns with the scientific definition of glaciation.
• The second option: Mountains are formed through processes like tectonic activity (e.g., plate collisions), not glaciation. Glaciation can shape mountains (e.g., glacial erosion), but not form them.
• The third option: Melting ice caps due to global warming is related to deglaciation or ice loss, not glaciation (which is about ice formation/accumulation).

Answer:

A. Glaciation is the process whereby snow has been converted to ice by the force of gravity and pressure.
