Speed Match Review Game

This game has been played times
The best time ever was at seconds.
The best time today is at seconds.
How To Play:
Drag the squares in the gray area and drop them in the matching squares in the blue area below.
If you drop a square in the correct spot, it will disappear.
If you make a mistake, the square will return to its original spot.
Good luck!

Freezing and thawing (Water enters the small cracks in rocks, freezes, and then expands. This causes the cracks to widen.)
Acids (Water soaking into soil disssolves acids that react with the minerals in rocks.)
FALSE. Chemical weathering occurs when the minerals in rocks chemically react with oxygen, acids, or carbon dioxide.
Carbon dioxide (Carbonic acid forms when carbon dioxide and rain water mix together. It reacts with minerals in rocks.)
Abrasion (Winds carry bits of sand that break apart the soft part of rocks.)
Plants or roots (A tree's roots force their way in rock. The roots grow, and the cracks widen and break the rock apart.)
True
Exfoliation (Layers of heavy rock wear away. You can see many layers of the rock.)
Chemical weathering changes the minerals that make up a rock. Physical weathering does not-- it only changes the shape and size of rocks.
Oxygen (Oxygen + Water + Iron = Rust)
Weathering
Horizons
Erosion
Deposition
Chemical Weathering
There are 3 causes of chemical weathering: Decaying plants put ________ in soil. This causes rocks to break down and look like this:
There are 4 causes of physical weathering. What caused this rock arch to form?
True or False: Physical weathering causes rocks to change size and shape.
_________is the transport of weathered rock.
_________ is the breaking down of rocks.
True or False: Chemical weathering is caused by freezing and thawing, exfoliation, abrasion, or plants.
There are 3 causes of chemical weathering. Water and _______ gas form carbonic acid which caused this limestone cave to form.
_____________is the dropping off of weathered rock.
There are 4 causes of physical weathering. What has caused Half Dome's layers to peel off like the layers of an onion?
Layers of soil are called _________________.
There are 4 causes of physical weathering. What has caused this rock to crack?
There are 4 causes of physical weathering. What caused this sidewalk to break apart?
There are 3 causes of chemical weathering. Water and ________ mixed to create rust on this rock.
How is chemical weathering different than physical weathering?
A rock can break down when minerals in the rock are changed chemically. This is called _________________.
