Erosion 5 Agents Potluck

What is the process that breaks down rock and other substances?

weathering

What is the physical process that breaks down rock into smaller

pieces?

mechanical weathering

What is the process that breaks down rock through chemical changes?

chemical weathering

What are the two most important factors that determine the rate at

which weathering occurs?

type of rock and climate

In what climate will weathering occur the fastest?

hot and wet

What is the name given to weathering that occurs as a result of repeated freezing and thawing of water? Double your points if

you can tell me the type of weathering this is.

frost wedging; mechanical

What do we call weathering that occurs as a result of oxygen

reacting with water and iron? Double your points if you can tell

me the type (mechanical or chemical) of weathering.

oxidation; chemical

What is the type of weathering that occurs when feldspar turns to clay? Double your points if you

can tell me the type of weathering.

hydrolysis; chemical

What is the type of weathering that occurs as a result of repeated

heating and cooling? Double your points if you can tell me the

type of weathering.

thermal expansion; mechanical

How can plants cause both mechanical and chemical

weathering?

root pry and plant acids

What is the movement of particles by wind, water, ice,

gravity, or waves?

erosion

What is the material moved by erosion called?

sediment

What process must occur before erosion can occur?

weathering

What agent causes the greatest amount of erosion?

water

What form of mechanical weathering can be found in most erosion

circumstances?

abrasion

Which agent of erosion includes plucking and abrasion?

glaciers

Which agent of erosion was responsible for problems in the

Dust Bowl?

wind

Which agent of erosion occurs both above and below ground?

water

Which agent of erosion involves impact and abrasion?

waves

Which agent of erosion involves slump, creep, and landslides?

Add 200 points if you can tell me what these are types of.

gravity; mass movement

What occurs when agents of erosion lay down sediment?

deposition

What type of weathering is acid rain?

chemical weathering

What is the type of weathering that causes layers of rock to be uploaded

as a result of pressure release?

exfoliation

What do weathering, erosion, and deposition have in common? Add 200 points if you can name more

than one similarity.

shape and change Earth’s surface; part of a cycle; all have

to do with sediment

How can weathering, erosion, and deposition happen at the

same time? Add 500 points if you can describe a situation that

involves more than two.

Examples:Wind (erosion, abrasion, deposition)

Water (weathering, erosion, abrasion, deposition)

Waves (abrasion, erosion, deposition)

Glaciers (erosion, abrasion, deposition)
