Weathering, Erosion and Glaciers

Front

What is ice wedging?

Back

Ice wedging is a type of mechanical weathering where water seeps into cracks in rocks, freezes, and expands, causing the rocks to break apart.

Front

What is erosion?

Back

Erosion is the process that picks up and moves weathered rocks and soil from one location to another, often caused by water, wind, or ice.

Front

How do ocean waves contribute to cliff formation?

Back

Ocean waves wash away rock material at the base of cliffs, leading to erosion and the gradual formation of cliffs.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces through physical, chemical, or biological means.

Front

Why does water expanding when it freezes cause weathering?

Back

When water freezes, it expands, exerting pressure on the surrounding rock, which can lead to cracks and eventual breaking of the rock.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks, while erosion is the movement of those weathered materials.

Front

What role do plant roots play in weathering?

Back

Plant roots can grow into cracks in rocks, and as they expand, they can break the rocks apart, contributing to weathering.

Front

What is deposition?

Back

Deposition is the process by which eroded materials are dropped off in a new location, forming new landforms.

Front

What is the impact of acid rain on rocks?

Back

Acid rain can chemically weather rocks by dissolving minerals, leading to the breakdown of the rock structure.

Front

How does wind contribute to erosion?

Back

Wind can pick up and carry small particles of soil and sand, eroding surfaces and reshaping landscapes.
