100

This type of process happens quickly and affects a small area.

What is a small-scale process?

100

These processes happen very quickly (seconds to days)

What are fast processes?

100

This is the process of breaking down rock into smaller pieces.

What is weathering?

100

This process moves sediment from one place to another.

What is erosion?

100

This ocean is surrounded by the Ring of Fire

What is the Pacific Ocean?

200

This type of process takes a long time and affects large areas.

What is a large-scale process?

200

Weathering and erosion are examples of this type of time scale.

What is slow processes?

200

This type of weathering involves physical forces like ice cracking rock

What is mechanical weathering?

200

This process drops sediment in a new location.

What is deposition?

200

The Ring of Fire is known for these two geologic events.

What are earthquakes and volcanoes?

300

An earthquake is an example of this type of process.

What is a small-scale process?

300

This is a fast geologic event that shakes the ground.

What is an earthquake?

300

This type of weathering changes the chemical composition of rock.

What is chemical weathering?

300

Wind, water, ice, and gravity are all examples of this.

What are agents of erosion?

300

This process causes plates to move and creates activity in the Ring of Fire.

What is plate tectonics?

400

Mountain building is an example of this type of process.

What is a large-scale process?

400

This type of time scale takes thousands to millions of years.

What is a slow time scale?

400

Ice wedging is an example of this type of weathering.

What is mechanical weathering?

400

This landform is created when sediment is deposited at a river’s mouth. (Think:  Where the river meets the sea)

What is a delta?

400

This occurs when one tectonic plate sinks beneath another.

What is subduction?

500

Explain how small-scale processes can create large-scale changes over time.

What is repeated small changes (like erosion) building up over long time to form large landforms?

500

Why do scientists study rock layers to understand time scales?

What is because they provide evidence of changes over long periods of time?

500

Explain the difference between mechanical and chemical weathering.

What is mechanical breaks rock physically, while chemical changes its composition?

500

This is the proper order of breaking down rock material

What is weathering → erosion → deposition?

500

Why does the Ring of Fire have so many volcanoes?

What is because many plate boundaries and subduction zones are located there?
