Erosion and Deposition Assignment

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by wind, water, or ice and transported to another location.

Front

What is deposition?

Back

Deposition is the geological process in which sediments, soil, and rocks are added to a landform or land mass, often occurring after erosion.

Front

What is creep in geology?

Back

Creep is a slow, gradual movement of soil and rock down a slope, often affecting structures like roadways and fences.

Front

What role do glaciers play in erosion?

Back

Glaciers erode the landscape by scraping and carving out valleys, leaving behind features like U-shaped valleys and striations.

Front

What are erratics?

Back

Erratics are large boulders that have been transported by glacial ice and left behind as the glacier melts.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks and minerals at the Earth's surface, while erosion involves the movement of those materials from one location to another.

Front

How do ocean waves contribute to erosion?

Back

Ocean waves erode coastlines by crashing against rocks and sediment, leading to the formation of features like cliffs and beaches.

Front

What is the significance of running water in erosion?

Back

Running water is a powerful agent of erosion, shaping landscapes by carving out river valleys and transporting sediments.

Front

What are moraines?

Back

Moraines are accumulations of dirt and rocks that have been pushed along by a glacier, often forming ridges.

Front

What are striations?

Back

Striations are scratches or grooves on bedrock caused by the movement of glaciers over the rock surface.
