Vocab/Processes
What is water abrasion?
What is when rocks rub, grind, tumble, and roll over one another as moving water pushes them.
How is physical weathering different from chemical weathering?
What is the process by which larger rocks crack and break apart over time to form smaller rocks?
Chemical weathering causes rock to become weaker/stronger (pick one)
What is weaker?
What mineral is in both limestone and marble?
What is calcite?
What causes rocks to fall to the bottom of a mountain or cliff? Give an example: HINT: OLD MAN
What is gravity, time, and weathering?
What is an example of plant growth causing physical weathering?
What is plant/tree roots in cracks in rocks?
Oxidation causes what to happen to rock? What is the scientific name for this?
What is rust, or iron oxide?
Landslides is a type of physical/chemical weathering.
Physical
What is weathering?
What is the process by which larger rocks crack and break apart over time to form smaller rocks?
What is the rubbing, grinding, and bumping of rocks that cause physical weathering?
What is abrasion?
What causes acid rain to occur?
What is pollution/ carbon dioxide in the air?
What can cause a chemical reaction with minerals in rocks to make new minerals?
What is salt, and acid rain?
What is a chemical reaction?
What is when two or more materials mix and cause a reaction that changes the surface of a rock (break down) and can form a new material?
When water gets into cracks in rock and freezes, what happens?
What is the ice expands between the cracks and pushes the rocks to crack more or break apart?
What living things produce acid?
What is moss and lichens?
Describe wind abrasion.
What is wind can blow sand against rocks and the sandblasting weathers the rocks?
What causes big rocks to break down into smaller rocks?
What is rocks break down because of physical weathering due to abrasion, freezing and thawing of water/ice, wind, plants, and animals.
When animals dig burrows, is it an example of physical weathering. Why?
What is the rocks crack and break up against other rocks or trees causing physical weathering?
How is iron oxide formed?
What is many rocks contain iron which can rust when it comes in contact with oxygen in the air, becoming iron oxide?
What happens when water mixes with carbon dioxide to make carbonic acid?
What is carbonation?
