Weathering & Erosion

Which agent of erosion causes landslides?

• wind

• waves

• water

• gravity

The process by which rocks are broken down chemically or physically is known as:

• Weathering
• Erosion
• Deposition
• Transportation

When wind, water, or ice leave materials in a location, this is known as:

• Weathering
• Erosion
• Deposition
• Transportation

What kind of weathering causes the mineral composition of rocks to change?

• mechanical weathering
• permeable weathering
• chemical weathering
• physical weathering

A rock containing iron becomes soft and crumbly and reddish-brown in color.  It probably has been chemically weathered by -

• abrasion
• carbon dioxide
• oxygen
• acid rain

A hot wet climate causes weathering to take place -

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

The most important factors in determining the rate of weathering are - 

• carbon dioxide and acid rain
• abrasion and acids from plant roots
• animal actions and oxygen
• rock type and climate

Sand dunes and mushroom rocks are formed by which agent of erosion?

• water

• ice

• wind

• gravity

What is the movement of sediment from place to place called?

• weathering

• erosion

• deposition

• exfoliation
