Weathering, Erosion, Deposition, and Law of superposition

Front

What is weathering?

Back

The process of breaking down rocks into smaller pieces by natural forces such as wind, water, and temperature changes.

Front

What is erosion?

Back

The process by which soil and rock are removed from one location and transported to another by natural forces like water, wind, or ice.

Front

What is deposition?

Back

The process where sediments, soil, and rocks are added to a landform or land mass, often occurring after erosion.

Front

What is a landslide?

Back

A mass movement of rock, earth, or debris down a slope, often occurring quickly due to gravity.

Front

What is the Law of Superposition?

Back

A geological principle stating that in undisturbed sedimentary rock layers, the oldest layers are at the bottom and the youngest are at the top.

Front

What is a mudslide?

Back

A type of landslide that involves a flow of mud and debris, often triggered by heavy rainfall.

Front

What is the Kaibab formation?

Back

A geological formation in the Grand Canyon that is relatively young compared to other rock layers.

Front

What is the Zoraster Granite?

Back

An ancient rock formation in the Grand Canyon, known to be one of the oldest layers.

Front

How do contour lines represent elevation?

Back

Contour lines on a map connect points of equal elevation, helping to visualize the terrain's shape.

Front

What is the significance of the Redwall limestone?

Back

A prominent rock layer in the Grand Canyon, known for its thickness and fossil content.
