Front

What is erosion?

Back

Erosion is the process by which natural forces like wind, water, and ice move soil and rock from one location to another.

Front

How does water cause erosion?

Back

Moving water carries away sediment, which can lead to the formation of gullies or ditches over time.

Front

What is weathering?

Back

Weathering is the process that breaks down rocks into smaller pieces through physical or chemical means.

Front

What is the Ring of Fire?

Back

The Ring of Fire is a region around the edges of the Pacific Ocean where many volcanoes and earthquakes occur due to tectonic plate movements.

Front

Name three causes of erosion.

Wind, water, and ice.

Front

What happens when water fills cracks in rocks and freezes?

Back

The water expands as it freezes, making the cracks larger over time.

Front

What is a subduction zone?

Back

A subduction zone is an area where one tectonic plate moves under another, often leading to volcanic activity.

Front

How do the Himalayas form?

Back

The Himalayas formed when the Indian Plate collided with the Eurasian Plate, pushing the land upward.

Front

What is sediment?

Back

Sediment is small particles of rock and soil that are carried by wind or water.
