Geological Processes and Landforms

The video explains how various landforms are shaped by weathering and erosion. It covers wind-formed structures like buttes, mesas, and plateaus, water-formed features such as beaches and dunes, and glacial landforms including valleys and drumlins. Coastal and river landforms like sandbars and spits are also discussed, along with the effects of erosion on cliffs and lakes. The video further explores large-scale water formations like bays and gulfs, and concludes with volcanic and tectonic landforms such as peninsulas and islands.

What is the primary process involved in the formation of buttes?

• Volcanic activity

• Wind weathering and erosion

• Tectonic plate movement

• Water deposition

How are plateaus different from buttes and mesas?

• They are formed by water erosion

• They are formed on a much larger scale

• They are formed by volcanic activity

• They are formed by tectonic uplift

What natural force primarily shapes beaches?

• Glaciers

• Volcanoes

• Water

• Wind

What is a U-shaped valley primarily formed by?

• Volcanic activity

• River erosion

• Glacial movement

• Wind erosion

What indicates the direction a glacier was moving when forming a drumlin?

• The color of the sediment

• The size of the rocks

• The higher end of the drumlin

• The shape of the valley

How is a spit formed?

• By water current depositing sediment

• By tectonic uplift

• By volcanic eruption

• By wind blowing sand

What is the main difference between a canyon and a ravine?

• Canyons are formed over millions of years

• Canyons are formed by wind

• Ravines are larger than canyons

• Ravines are formed by volcanic activity

What can cause a lake to shrink over time?

• Increased rainfall

• Sediment filling it in

• Glacial movement

• Volcanic eruption

How can a sea form from a large bay?

• By volcanic eruption

• By tectonic plate movement

• By wind erosion

• By glacial melting

What is a delta primarily formed by?

• Volcanic activity

• Glacial erosion

• River sediment deposition

• Wind deposition
