Earth's Surface: Exploring Landforms and Natural Changes

The video explores the surface of the Earth, focusing on landforms such as glaciers, mountains, valleys, canyons, and beaches. It explains how these landforms are shaped by natural processes like weathering, erosion, and deposition, as well as the impact of ice and mass movement. The video also discusses human activities that alter landforms, such as farming, building dams, and draining wetlands.

What is a glacier primarily composed of?

• Water and mud

• Sand and gravel

• Ice and snow

• Rock and soil

Which mountain is the tallest in North America?

• Mount Fuji

• Mount Everest

• Mount Kilimanjaro

• Denali

What is a canyon?

• A wide river

• A flat plain

• A deep ravine between cliffs

• A high mountain peak

How are beaches formed?

• By volcanic eruptions

• By tectonic plate movements

• By the accumulation of sand and sediment

• By the melting of glaciers

What is weathering?

• The process of forming new rocks

• The process of creating new landforms

• The process of moving sediment

• The process of breaking rock into smaller pieces

What role does wind play in shaping landforms?

• It causes earthquakes

• It forms new mountains

• It melts glaciers

• It moves sediment and creates features like dunes

What is mass movement?

• The movement of tectonic plates

• The downhill movement of soil and rock due to gravity

• The melting of ice caps

• The flow of rivers

How do humans change landforms through farming?

• By planting trees

• By using floodplains and deltas for agriculture

• By building skyscrapers

• By mining for minerals

Why do people build dams?

• To increase rainfall

• To control river flow and generate electricity

• To prevent earthquakes

• To create new beaches

What is the purpose of redirecting water into desert areas?

• To prevent sandstorms

• To create new lakes

• To make the land suitable for living

• To increase desert size
