Choose the arrow(s) that represent WEATHERING AND EROSION.
Soil with the smallest particle size that holds soil firmly in place;
Clay
Soil
Gravel
Sand
A type of chemical weathering in which a substance combines with oxygen, as when iron oxidizes, forming rust.
Acid rain
Oxidation
Exfoliation
How does wind weather a rock?
The wind slowly drills a hole in the side of a rock.
The wind smashes big rocks against each other.
The wind shakes the big rock and makes it weak.
The wind blows tiny pieces of rock against a big piece of rock. The tiny pieces slowly break the big piece.
What is a major cause of soil erosion?
Moving Water
Overgrazing
Agricultural Activities
These rocks were broken apart from the continuous freeze/thaw of water in the cracks of the rocks. This is an example of:
ice or frost wedging
acid rain
permeability
abrasion
A piece of sandstone changing color (from brown to rusty red) from exposure to water and air is an example of:
mechanical weathering
chemical weathering
The formation of large cracks in the face of a mountain from ice wedging is an example of:
mechanical weathering
chemical weathering
Can animals cause mechanical weathering?
yes. They can create burrows through the ground.
no,animals can't dig burows
no,only ice can cause mechanical weathering
yes,animals eat their way through the sediment
Humus is:
the part of soil made up of decayed parts of once-living things.
a dip that is made of garbanzo beans.
a bone that can be found in the upper arm.
a sound people make when their lips are together.
Chase noticed after a heavy rainstorm that the loose dirt in his backyard had been moved around, creating channels and mounds. Select two of the processes that took place in Chase's backyard.
compacting
deposition
sedimentation
weathering
erosion
Which of the following is most likely to have happened in the image?
The plant has dissolved the rock.

The plant has eaten away the rock.
The plant has weathered the rock.
Which of the following processes involves the breakdown of rocks without changing their chemical composition?
Chemical Weathering
Mechanical Weathering
Erosion
Deposition
What is the primary agent of erosion that shapes landscapes by transporting sediments?
Wind
Water
Ice
Gravity
Which soil layer is rich in organic material and is crucial for plant growth?
Topsoil
Subsoil
Bedrock
Parent Material
In an experiment, a student observes that limestone reacts with acid rain and forms a new substance. This is an example of:
Physical Weathering
Chemical Weathering
Erosion
Sedimentation
