Erosion Vocabulary Quiz

What is the breakdown of rocks, soil, and other material into smaller pieces called?

• Erosion

• Deposition

• Weathering

• Abrasion

Answer explanation

The breakdown of rocks, soil, and other materials into smaller pieces is called weathering. This process involves physical and chemical changes that disintegrate and decompose materials, distinguishing it from erosion and deposition.

What term describes broken down rock, soil, or other material?

• Moraine

• Sediment

• Stalagmite

• Delta

Answer explanation

The term 'sediment' refers to broken down rock, soil, or other material that has been transported by wind, water, or ice. Moraine, stalagmite, and delta are specific geological features, not general terms for such materials.

What is the process by which weathered rock, sediment, or soil is moved to a new location?

• Deposition

• Weathering

• Erosion

• Sinkhole

Answer explanation

Erosion is the process that moves weathered rock, sediment, or soil from one location to another, often through wind, water, or ice. In contrast, deposition refers to the settling of these materials, while weathering is the breakdown of rocks.

What is the dropping off of sediment to a new location called?

• Deposition

• Erosion

• Weathering

• Abrasion

Answer explanation

The dropping off of sediment to a new location is called deposition. This process occurs when materials carried by wind, water, or ice settle and accumulate, forming new landforms.

What is the scraping and scratching of rocks by loose particles moved over the rocks by erosion?

• Stalactite

• Abrasion

• Moraine

• Groundwater

Answer explanation

The scraping and scratching of rocks by loose particles moved by erosion is known as abrasion. This process occurs when wind, water, or ice carries particles that wear down surfaces, making 'abrasion' the correct answer.

What is a depositional landform that forms where a river enters a large body of water and creates a pile of sediment?

• Canyon

• Delta

• Stream

• Till

Answer explanation

A delta is a depositional landform that forms where a river meets a larger body of water, causing sediment to accumulate and create a landform. This distinguishes it from canyons, streams, and till, which are different geological features.

What is a cave with a collapsed roof called?

• Stalagmite

• Sinkhole

• Moraine

• Canyon

Answer explanation

A cave with a collapsed roof is known as a sinkhole. This occurs when the ground above a cave becomes unstable and collapses, creating a depression or hole in the ground.

What is a chamber or cavern typically formed underground by natural processes like erosion?

• Cave

• Stream

• Delta

• Moraine

Answer explanation

A cave is a natural underground chamber formed by processes like erosion, typically through the dissolution of rock. Other options like stream, delta, and moraine refer to different geological features.

What is a depositional landform rising from the floor of a limestone cave?

• Stalactite

• Moraine

• Stalagmite

• Delta

Answer explanation

A stalagmite is a depositional landform that rises from the floor of a limestone cave, formed by the accumulation of mineral deposits from dripping water. In contrast, stalactites hang from the ceiling.

What is a depositional landform hanging from the roof of a limestone cave?

• Stalagmite

• Stalactite

• Moraine

• Sinkhole

Answer explanation

A stalactite is a depositional landform that hangs from the roof of a limestone cave, formed by the dripping of mineral-rich water. In contrast, stalagmites grow from the ground up, while moraines and sinkholes are unrelated geological features.
