Row 1
What is the process by which rocks are broken down into smaller pieces without changing their chemical composition?
Physcial weathering
A continuous process that forms and changes rocks is called?
The rock cycle.
The process of materials being moved from one location to another is called?
Erosion
Which type of rock forms from cooled magma or lava?
Igneous rock
When granite changes to gneiss this is an example of
what?
Metamorphism
Weathering occurs when water freezes and expands in rock cracks. What type of weathering is this called?
Mechanical weathering
Which agent of erosion is primarily responsible for creating sand dunes?
Wind
Does temperature change contribute to chemical weathering? Why or why not?
No, because their is no chemical change in the rocks only a physical change.
Rust forming on rocks, plants creating acids that dissolve rock, and minerals dissolving in rainwater are all examples of what?
Chemical weathering
Rocks cracking from freeze-thaw cycle is an example of what type of weathering?
Mechanical weathering
Acid rain dissolving limestone is an example of ____?
Chemical weathering
When existing rocks are subjected to heat and pressure what rock does this process form?
Metamorphic rock
Sediment rocks form from________?
Compacted and cemented layers of sediments.
Which process would most likely create a canyon?
Water erosion
Name the three types of rocks.
Igneous, Sedimentary, and Metamorphic
What causes the polished appearance of river rocks?
Abrasion
What is the main difference between weathering and erosion?
Weathering breaks down rocks while erosion moves materials.
Which rock is most likely to contain fossils?
Sedimentary rock
Rocks can only change in one direction on the rock cycle. True or False?
False

Wind and water
The breakdown of rocks by living organisms is called?
Biological weathering
The process where sediments settle out of water or air is called?
Deposition
Erosion-transportation-deposition is the correct order of rock formation in a what?
Stream
