Formation and Changes of Land

The video explains how the land around us has changed over billions of years. It covers the processes of deposition, where wind and water deposit particles to form land features like dunes and stone banks. Additionally, it describes how lava from volcanic activity creates new land as it cools and solidifies.

• Deserts and ice caps

• Vast oceans and swamps

• Forests and grasslands

• Mountains and valleys

What is the process called when particles are dropped by wind or water to form new land?

• Erosion

• Sedimentation

• Deposition

• Weathering

Which natural feature is formed by wind depositing sand over many years?

• Mountains

• Canyons

• Valleys

• Dunes

What happens to lava when it spreads out and cools?

• It evaporates

• It turns into water

• It becomes gas

• It forms new land

Which of the following is NOT a way land can form?
