100
This type of mechanical weathering is found in areas with large trees.
What is root pry?
100
This is the type of chemical weathering that occurs when oxygen combines with iron to form rust.
What is oxidation?
100
This type of rock contains silicon, oxygen and a metal.
What is a silicate?
100
This states that sediments are deposited in horizontal layers.
What is the Law of Horizontality?
100
This area would have large deposits of limestone and sinkholes.
What is Karst Topography?
200
This occurs when rocks tumble against other rocks as they are carried by running water.
What is abrasion?
200
This is the type of chemical weathering that occurs when compounds combine with water to form acids and the acids react with rocks.
What is dissolution?
200
This type of rock contains the elements carbon and oxygen.
What is a carbonate?
200
This states that the older of two rock layers is on the bottom.
What is the Law of Superposition?
200
This is the cause of an unconformity found in rock layers.
What is erosion?
300
This type of mechanical weathering is found in areas where temperatures reach freezing at night and warm up during the day.
What is ice wedging?
300
This is the chemical name for rust.
What is iron oxide?
300
A rock has HCl added to it and gas bubbles form causing fizzing. It most likely belongs to this rock group based on chemical composition.
What are carbonates?
300
This states that a fault, fold or igneous intrusion that cuts across layers of rock is younger than the rock.
What is the Law of Cross Cutting Relationships?
300
This determination of rock age is based on examining the position of layers in a sequence.
What is relative age dating?
400
This is the type of weathering caused when we shook the granite, limestone and marble in the tennis can.
What is mechanical weathering (abrasion)?
400
This is the reason you would not want to use marble in your construction of buildings.
What is chemically reacts with acids (dissolution)?
400
This type of rock is often found on your countertops because it does not react to acids like limestone and marble do.
What is granite?
400
An anticline forms in rock layers. This law explains why the rock layers are older than the anticline.
What is Law of Cross Cutting Relationships?
400
This surface is found in rock layers that have been exposed to erosion.
What is an unconformity?
500
You are asked to calculate the density of a rock sample and then place it in a tennis can for 3 minutes of shaking. This explains why when asked what the density after shaking is, you already have the answer.
What is the chemical composition of the rock is not changed by mechanical weathering, just broken down into smaller pieces therefore density will remain the same?
500
These are found in areas that have rocks that are easily dissolved by carbonic acid.
What are caves?
500
Uplift and Erosion contribute to this part of the rock cycle
What is weathering?
500
This states that the rock "picked up" by an igneous intrusion is older than the intrusion.
What is Law of Inclusion?
500
This law explains why you might find a fragment of rock that does not match the layer that it is found in.
What is the Law of Inclusion?
