Weathering, Erosion, and Deposition
Forming Landforms
Wind Erosion and Water Erosion
More Erosion
Name that landform

What happens to water in a rock as it freezes?
It expands and cracks the rock.
100
What causes the Mississippi River Delta?
Erosion taking sediments by fast-moving water to the mouth of the river.
100
Where will wind most likely cause erosion beaches or forests? Why?
Beaches because the wind blows the sand
100
Name the three types of erosion.
Wind erosion, water erosion, glacial erosion

Canyon.
This is Palo Duro Canyon in Texas

Mrs. Lawson placed a wooden board outside to show her students the effects of weathering and erosion. She says they won't be able to see any changes for several months. Why?
Weathering and erosion happen slowly over a long period of time.
200
Name a landform that is created by moving water. 100 points for every landform named!
Canyons or deltas
200
Wind and water are the forces responsible for forming...
sand dunes
200
What type of water causes the most erosion?
flash flooding or fast-flowing water
200
A delta. This is the Copper River Delta in Cordova, Alaska
300
How does a sand dune form?
When the particles of sand are eroded by the wind and deposited in a new location repeated.
300
Name a landform that causes soil erosion as it scrapes against the land.
Glacier
300
What happens to soil and sediment along a river during a rainstorm?
It is washed downstream and deposited somewhere else.
300
Which type of weather causes a great amount of water erosion?
Floods
300
Sand dunes. This is the Monahans Sand Dunes in Monahans, TX
400
How and where do deltas form?
Eroded sediment and sand is deposited at the mouth of a river
400
How are canyons formed?
Water erosion
400
Define deposition. Give an example.
Deposition is the depositing/dropping of sediment.
One example is a river washing sediment and forming a delta.
400
What is the reason for planting wooden stakes near a beach?
To keep the sand from being blown away rapidly and prevent erosion
400
Delta. The Brazos River Delta in Texas.
500
Which is a process that can break a rock - deposition, weathering (frost wedging), erosion? Daily double: Define frost wedging
Weathering can break a rock. Frost wedging is when water fills a crack, water freezes expands and breaks rock.
500
A deep, narrow valley with steep sides is...
a canyon
500
True or False - Weathering can create a hole in a huge boulder.
True
500
On the video of the stream table experiment, what type of flow caused the most erosion? Why?
The flood because it was the most water and the fastest flowing.

Canyon. This is a picture of the Texas Slot Canyon in Texas
