Earth's Surface Formation and Processes

The video explains how various processes shape the Earth's surface, forming landforms like canyons and plateaus. Slow processes such as weathering and erosion, and rapid events like volcanic eruptions and earthquakes, contribute to these formations. Canyons are formed over millions of years by river erosion, while plateaus can form through crust uplift, lava flow, or erosion of surrounding areas.

What are the two types of processes that shape the Earth's surface?

• Erosion and deposition

• Volcanic and tectonic processes

• Rapid and slow processes

• Weathering and erosion

Which landform is created by the weathering and erosion of uplifted sedimentary rock?

• Plateau

• Valley

• Mountain

• Canyon

How long did it take for the Grand Canyon to form?

• 5 to 6 million years

• 1 to 2 million years

• 7 to 8 million years

• 3 to 4 million years

What causes the formation of canyons?

• River erosion

• Tectonic uplift

• Sediment deposition

• Volcanic activity

Which landform is characterized by steep slopes or cliffs?

• Mountain

• Canyon

• Valley

• Plateau

What is a dissected plateau?

• A plateau formed by volcanic eruptions

• A plateau formed by the upward movement of the Earth's crust

• A plateau formed by the erosion of surrounding areas

• A plateau formed by sediment deposition

Which type of plateau is formed by lava flow?

• Dissected plateau

• Sedimentary plateau

• Volcanic plateau

• Erosional plateau

What is the result of numerous volcanic eruptions?

• Valley

• Canyon

• Volcanic plateau

• Dissected plateau

How can plateaus be formed aside from volcanic activity?

• By tectonic uplift

• By the erosion of surrounding areas

• By river erosion

• By sediment deposition
