The difference between weathering and erosion is:
a. weathering causes a quick change in landforms and erosion causes a slow change in landforms.
b. weathering breaks rocks into sediments and erosion moves sediment from one place to another.
What is B?
100
Small pieces that break off of rocks, settle, and form layers on top of one another.
What is sediments?
200
Mountains, canyons, valleys and other surface features of the land.
What are landforms?
200
When rainwater seeps into cracks in rocks and __________, it expands and causes the rock to split apart.
The difference between erosion and deposition is:
a. erosion moves sediment from one place to another and deposition is a physical feature on the Earth.
b. deposition is the process of dropping , or depositing , sediment in a new location and erosion is the process of moving sediment from one place to another.
What is B?
200
A type of rock that forms when layers of sediment are squeezed and compacted together over a long time. We oftentimes find fossils in them.
What is a sedimentary rock?
300
The process by which weathered rock is picked up and moved to a new place.
What is erosion?
300
Weathering over long periods of time breaks rock into ____________ pieces. (larger or smaller)
What is smaller?
300
Water carries small pieces of rock away from a canyon.
Is this an example of weathering, erosion, or deposition?
What is erosion?
300
Name a difference between weathering and erosion.
What is weathering makes things smaller, and erosion moves it?
300
A growing pile of deposited sediment at the mouth of a river.
What is a delta?
400
Remains or evidence of plants and animals that lived long ago
Fossils
400
Sand particles travel farther in a river than clay particles because they are smaller in size. True or False?
What is False?
400
Water can weather rock by:
A. eroding soil
B. by freezing and melting
What is freezing and melting?
400
Name a difference between the fossils we made in class, and the fossils we find in nature.
What is our fossils formed very quickly, OR one of our rock layers was made of plaster.
400
A type of fossil that forms when minerals seep into the empty space where an organism once was, forming an exact replica of it.
What is a cast?
500
When weathered rock and soil slows down, stops moving, and settles.
What is deposition?
500
All of the following are forces that change landforms EXCEPT:
a. wind b. moving water c. gravity d. physical features
What is d. physical features?
500
Which stream table would produce the fastest changes in the soil (canyons, valleys, and deltas).
A. Regular water flow, no slope
B. Regular water flow, slope
C. Flood water flow, slope
What is C. Flood water flow, slope stream table
500
The difference between physical and chemical weathering is:
A. Physical weathering just breaks things apart and chemical weathering changes the rocks forever.
B. Physical weathering breaks things apart and chemical weathering burns rocks with chemicals.
What is A?
500
A type of fossil that forms when an organism dies in a layer of sediment and decomposes, leaving behind an empty space or outline of its shape.
