GOL 105 Q2 Exam Review Flashcardizz

Front

What is a normal fault?

Back

A normal fault is a type of fault that occurs when the crust is extended, causing the hanging wall to move downward relative to the footwall, typically resulting from tension.

Front

What happens to a glacier when there is more ablation than accumulation?

Back

When there is more ablation (removal) than accumulation (addition) of glacial snow/ice, the glacier will retreat.

Front

True or False: Large dust storms can carry chemicals and diseases across oceans.

Back

True. Large dust storms can cross entire oceans and carry not only dust but also chemicals, diseases, and microscopic organisms.

Front

What is a terminal moraine?

Back

A terminal moraine is a deposit that forms at the furthest point a glacier ever reaches, marking the maximum advance of the glacier.

Front

What characterizes the movement at reverse faults?

Back

At reverse faults, the hanging wall moves upward relative to the footwall, typically due to compressional forces.

Front

What is a reverse fault?

Back

A reverse fault is a type of fault where the hanging wall moves up relative to the footwall, usually caused by compressive stress.

Front

Define ablation in the context of glaciers.

Back

Ablation refers to the processes that remove snow and ice from a glacier, including melting, sublimation, and calving.

Front

What is a lateral moraine?

Back

A lateral moraine is a ridge of debris that accumulates along the sides of a glacier, formed from material that has fallen onto the glacier from the valley walls.

Front

What is the difference between accumulation and ablation?

Back

Accumulation is the addition of snow and ice to a glacier, while ablation is the removal of snow and ice from a glacier.

Front

What is a medial moraine?

Back

A medial moraine is a ridge of debris that forms in the middle of a glacier, created when two glaciers merge and their lateral moraines combine.
