Weathering and Erosion Test

The growth of plant roots and animal activity cause

• mechanical weathering
• erosion
• chemical weathering
• abrasion

What is weathering?

• a type of climate
• the movement of rock and sediment from one place to another
• the breaking of rock
• the setting down of sediment in a new area

When a rock containing iron is chemically changed and becomes soft and crumbly and reddish-brown in color:

• abrasion
• carbon dioxide
• oxidation
• acid rain

The type of mechanical weathering in which rock is worn away by the grinding action of other rock particles is called

• erosion
• cracking and peeling
• abrasion
• ice wedging

A hot and wet climate causes weathering to take place

• slowly
• at the same rate as when the climate is cool and dry
• unevenly
• quickly

Ice wedging breaks apart rocks by

• heating and cooling
• plant growth
• animal actions
• freezing and thawing of water

When the mineral composition of rocks change, it is this type of weathering

• mechanical
• chemical
• permeable
• general

Which of the following can help prevent mudslides and erosion?

• rain
• wind
• sand
• plants

How can erosion change mountains over many years?

• it can make the peaks taller
• it can make the mountains shorter
• it can move the mountain west
• it can cause a volcano
