Mechanical weathering

Wind weathering

Chemical weathering

Which type of climate would cause the greatest rate of weathering?

Cold and dry

Cold and humid (wet)

Warm and humid (wet)

Warm and dry

A student hiking in a rock area on a mountain notices that wide, deep cracks have formed in some of the large rocks. Some of the cracks are so large that the rocks have broken apart. Which process most likely caused these rocks to crack and creak?

Erosion by wind

Water freezing and thawing

Erosion by fast-moving

Sediments being deposited.

The surfaces of old concrete statues are often covered with small holes or pits. Which of these MOST LIKELY causes these holes or pits?

The concrete becomes pitted as water freezes in small cracks in the statue.

The concrete is chipped away by sand particles blown by strong winds

The concrete is chemically weathered by acid rain.

Long exposure to sunlight causes the pits to form.

What is the weathering process in which rocks are broken down into smaller pieces (sediments) and do not change the rock composition?

Acid weathering

Gravity weathering

Chemical weathering

Mechanical weathering

Which of the following is the most important agent of chemical weathering to form this cave?

Water - It can carry acid and dissolve rock

Erosion - Moves the rocks from one place to another

Wind - It displaces rocks

Exfoliation - New cracks give chemical reactions the chance to operate

Weathering is the process of -

Moving sediment from one place to another

Dropping or leaving sediment in a location

Breaking down rocks into sediment

An example of physical weathering is -

Plant roots and leaves releasing acids

Carbonic acid dissolving limestone

Large temperature changes

Lichens growing on rocks

Over millions of years, weak carbonic acid can dissolve limestone to form -

Cracks in rocks

Caves and caverns

Mountains and cliffs

10.

Fallen plant leaves help break down rocks as they -

Release or leach acids as they decompose

Get into cracks, expand, and make the cracks wider

Scratch and wear away the surface of rocks

11.

_________is the movement of sediment from one place to another.

Erosion

Weathering

Deposition

Movin on up!

12.

How does freezing water cause the weathering of rocks? The freezing water—

keeps the rocks in place

makes the rocks last longer

causes rocks to fall in landslides

expands cracks and breaks rocks

13.

How is mechanical weathering different from chemical weathering?

Chemical weathering happens over much shorter time frame than mechanical weathering.

Chemical weathering changes the chemical composition of rocks; mechanical weathering does not.

Chemical weathering occurs only in tropical climates; mechanical weathering occurs only in cool climates.

Chemical weathering occurs only in the mountains; mechanical weathering occurs only on flat land.

14.

Weeds growing into the cracks in a sidewalk and the sidewalk begins to crumble is an example of:

mechanical weathering

chemical weathering

mechanical weathering

chemical weathering
