100

The breaking down of rocks into smaller pieces

Weathering

100

The freezing of water in the cracks of rocks to break them apart.

Frost Wedging

100

This type of weathering occurs when rain mixes with Carbon Dioxide and other chemicals that can break down rocks.

Acid Rain

100

These can be formed on the edge of the coast of large lakes and oceans from long term exposure to large waves.

Sea Caves

100

This type of mechanical weathering is caused by humans digging deep pits into the earth to extract materials.

Mining

200

The slowing down and settling of rocky material

Deposition

200

This type of mechanical weathering occurs when different objects hit against one another.

Abrasion 

200

This type of weathering occurs when iron mixes with water and oxygen to turn it a reddish brown color

Rust/Rusting

200

This is the common type of rock layer that forms in deltas from extended deposition as layers of sediment settle in the sea.

Sedimentary Rocks

200

These objects that can form from heavy erosion are sometimes hidden by roads or thin layers of dirt.

Sinkholes

300

The carrying of broken down materials by wind, ice, or water

Erosion

300

This is what happens when rocks get hot from the weather and expand, over time this can cause cracks in rocks.

Expansion/Thermal Expansion

300

Humans cause chemical weathering by using/burning these, especially when using vehicles.

Fossil Fuels/Gas

300

These biologic organisms can break down rocks by both mechanical and chemical weathering

Plants/Roots

300

These sometimes act as temporary bridges over sinkholes until a heavy object goes over them that will cause them to break.

Roads

400

The breaking down of rocky materials with the use of physical forces.

Mechanical Weathering

400

This type of mechanical weathering occurs when salt water dries on rocks near the ocean and forms unique "honeycomb" shapes on the rocks.

Crystallization/salt crystals

400

This type of chemical weathering can occur from plants or other living organisms breaking down rocks.

Biological Weathering

400

This state in the United States is known to be the sinkhole capital of America

Michigan

400

These geographic features can be formed over a long period of time from deposition where rivers and oceans meet.

Deltas

500

Breaking down rocks by having them interact with oxygen, acids, or other chemicals.

Chemical Weathering

500

THis type of mechanical weathering only happens on roadways, most common on blacktop.

Potholes

500

This type of rock is heavily weathered by acid rain.

Limestone 

500

This country has the worlds largest sinkhole that was undiscovered until 1994

China

500

This major natural disaster can occur when a large amount of rocks and debris get carried away all at once.

Landslide
