Lesson 17: Russia's Varied Landscape: Physical Processes at Work

Which physical process shapes land from below the crust?

• erosion

• glaciation

• volcanic activity

• time zones

Which of these natural forces causes glaciers to move?

• tectonic movement

• volcanic activity

• convection

• gravity

Which of these natural forces tend to wear down mountains?

• folding and faulting

• glaciation and erosion

• volcanic activity and flooding

• tectonic activity and sedimentation

Which of these is most likely to be changed by physical processes?

• Earth's crust

• Earth's oceans

• Earth's climate

• Earth's atmosphere

What is the main cause of major earthquakes?

• the eruption of volcanoes

• the movement of tectonic plates

• the cooling of Earth's inner core

• the weight of glaciers on Earth's crust

The Ring of Fire marks a zone of volcanic activity around the edge of which ocean?

• Arctic Ocean

• Atlantic Ocean

• Indian Ocean

• Pacific Ocean

Flooding often adds a fresh layer of soil to a floodplain. Which term in the diagram below best describes this process?

• erosion

• mass wasting

• deposition

The liquid rock that has erupted from a volcano is called

• lava

• magma

• sediment

• precipitation

Which layer of Earth shown in this diagram is made up of liquid rock called magma?

• the mantle

• the outer core

• the inner core

• the crust

Fold mountains form when

• tectonic plates collide, causing Earth's crust to wrinkle without breaking.

• tectonic plates collide, causing the crust to crack into giant blocks.

• a glacier moves through a region.

• a volcano erupts.
