Weathering, Erosion, and Deposition Assessment

Weathering is the process that:

• moves rocks from place to place
• breaks rocks into smaller pieces
• drops sediments in a new place
• melts rocks into magma

Erosion is the process that:

• breaks rocks into smaller pieces
• moves rock pieces from place to place
• makes magma under the ground
• hardens molten rock

Deposition happens when:

• sediments are picked up by wind
• particles are dropped in a new location
• rocks are broken into smaller pieces
• magma cools into igneous rock

Which of these is an example of physical (mechanical) weathering?

• Acid water dissolving limestone
• Water freezing in rock cracks and causing them to split
• Minerals changing because of heat deep underground
• sediments cementing together

Which term means “hot molten rock deep below Earth’s surface”?

• Sediment
• magma
• granite
• limestone

The Grand Canyon formed mostly by:

• deposition of sand dunes
• weathering from rain only
• erosion by a river over millions of years
• sudden volcano explosions

Sedimentary rocks form when:

• melted rock cools and hardens
• sediments are compacted and cemented together
• other rocks change due to heat and pressure
• rocks are dropped off in new places

Which of these is produced by deposition?

• Beaches and river deltas
• Volcano lava flows
• Magma chambers
• hurricanes

Which force is NOT a main cause of erosion?

• Water
• wind
• Ice (Glaciers)
• lightning

What is sediment?

• Hot melted rock
• Many pieces of broken rock and soil
• A kind of metamporphic rock
• a volcano
