The 3 processes that are used to create landforms are...
Weathering, Erosion, and Deposition
100
I pile up into "mounds" when the wind carries my sediments to a new location
Sand Dune

During the first step in the sedimentary rock process, rocks are broken into smaller pieces. What are the small pieces of broken rock called?
Sediments
100
Name one of the three rapid changes?
Volcanic Eruption
land/mud slide
Earthquake
200
The agent that is used mainly in the creation of a sand dune is...
Wind
200
I am the process that BREAKS rocks into smaller pieces.
Weathering
200
Over time sediments build up from settling in the water and create little areas of land where a river meets the ocean.
Delta
200
I am the step in the sedimentary rock process that uses pressure to push the deposited layers together.
Compaction
200
Which rapid change is caused by shifting tectonic plates along fault lines?
Earthquakes
300
The agent that is used mainly in the creation of a canyon is...
Water
300
I am the process that CARRIES or TAKES sediments from one place to another.
Erosion
300
I was formed in an area where a huge glacier once stood. As time passed the glacier slowly moves leaving a large gap in its place.
U-shaped valley
300
I am the step in the sedimentary rock process that glues all of the layers together to create new sedimentary rock.
Cementation
300
Which rapid change is caused by pressure under the Earth's surface? It is also the rapid change that created Hawaii.
Volcanic Eruptions
400
The agent that is used mainly in the creation of a U-shaped valley is __________. A very large piece of this agent is commonly called a _____________.
Ice, Glacier
400
I am the process that DROPS or lets sediments SETTLE in a new location.
Deposition
400
Rushing rivers constantly run across the surface of rock carving and eroding the land. Over time my sides become very steep. Usually a river is found at the bottom of my steep sides
Canyon or V-shaped valley
400
Place the processes of sedimentary rock in order
Weathering, Erosion, Deposition, Compaction, Cementation
400
What rapid change is caused the ground being over saturated with water from rain or snow and gravity?
Land slide or mud slide
500
Frost wedging is when the agent of _________ freezes inside of cracks and turns into __________ causing the cracks to expand.
Water, Ice
500
We learned about 4 different landforms. Which landforms use more than one process of change in order to form?
What processes do those landforms use?
Canyon- Weathering & Erosion
Sand Dune- Erosion & Deposition
500
Give a similarity and a difference for a U-shaped valley and a V-shaped valley.
*Hint this can be related to their agents and processes of change
Similarity: They both use erosion to move sediments
Differences: The agents used
* U-shaped= Ice/glacier
* V-shaped= Water

G: Compaction
H: Erosion
J: Deposition

What is an one advantage and one disadvantage of a volcanic eruptions?
advantages: creates new land, gives nutrients to the soil
disadvantages: wide spread destruction to property and ecosystems
