Earths Changing Surface
When moving water leaves soil behind, it is called________.
Deposition
_________ is the process of a natural force breaking down rock into smaller pieces.
Weathering
True or False: Rainwater can erode soil, rocks, and other objects and then deposit them in new places.
True
True or False: Water always changes the Earth's surface quickly.
False
True or False: Deposition occurs when eroded pieces never stop moving or settle
False: Deposition occurs when eroded pieces stop moving and settle
Weathering is the natural process of
breaking down rock
The process of moving weathered material away from its first location.
Erosion
Eroded materials deposited in new areas is called
sediment
Why is it important to know about the effects of weathering?
So we can prevent damage to our area/environment
Does deposition occur before or after erosion?
After
Which of the following is an example of how wind changes Earth’s surface in a desert?
A. sand ripples in the desert
B. desert plants clustered together
C. a pond forming after a storm
D. fog forming in the desert
Sand ripples in the desert
When a natural force stops moving and the weathered material is placed in a new location.
Deposition
Daily Double!!! Solid rock that is formed from deposited sediment is called
sedimentary rock
Name three forces that cause weathering
Heat, ice, water, wind, or living things
Deposition can refer to the buildup of ________ from the ground or chemical process
soil or sediment
True or False. Soil building up at the mouth of a river is an example of erosion.
False: an example would be water carrying soil from a garden to a sidewalk.
A slow moving river of ice.
Glacier
What is the process of ice wedging?
Cracks in a rock get bigger when water inside them freezes.
Daily Double!!!What example of weathering do we experience the most?
Rain/hurricanes
True or False: People are the main cause for deposition.
False
Name two landforms and an event that we discussed in class that were caused by wind or water.
The Grand Canyon, the Delicate Arch, the Dust Bowl
Any eroded material that is deposited in a new place.
Sediment
How does this river cause erosion?
The force of this water carries bits of weathered rock and soil as it moves.
Daily Double!!! In which way does extra rainwater in the stream cause weathering?
Rainwater carries sand that grinds down rocks in the stream
Name 3 things that cause deposition.
Wind, flowing water, or ice
