Glaciers: Nature's Powerful Sculptors

What is the primary way glaciers shape the land?

• By melting and forming lakes

• By carving huge chunks out of mountains

• By creating new mountains

• By causing earthquakes

What is the process called when glaciers pick up material as they move?

• Deposition

• Transportation

• Erosion

• Melting

What is freeze-thaw weathering?

• The process of glaciers melting and refreezing

• Water seeping into rock cracks, freezing, and expanding

• The melting of glaciers in warm weather

• The formation of ice crystals in the atmosphere

What is the term used when glaciers pull loose pieces of rock along with them?

• Abrasion

• Plucking

• Deposition

• Erosion

How do rocks and stones move along the glacier bed?

• By floating on water

• By being carried by wind

• By scraping along like sandpaper

• By rolling downhill

What is the term for the mixture of rocks, stones, sand, and clay left behind by glaciers?

• Glacial till

• Sediment

• Gravel

• Soil

What happens to the eroded material as the glacier flows downhill?

• It evaporates

• It is transported by the glacier

• It turns into soil

• It forms new glaciers

Why do glaciers often appear dirty?

• Because of pollution

• Due to the rocks and debris on top of them

• Because they are melting

• Due to algae growth

What happens to the rocks and stones when a glacier melts?

• They float away

• They are left behind

• They dissolve in water

• They turn into ice

What is the melted ice from glaciers called when it flows downhill?

• Rainwater

• Groundwater

• Meltwater

• Seawater
