The breaking down of rocks into smaller pieces
Weathering
The freezing of water in the cracks of rocks to break them apart.
Frost Wedging
This type of weathering occurs when rain mixes with Carbon Dioxide and other chemicals that can break down rocks.
Acid Rain
These can be formed on the edge of the coast of large lakes and oceans from long term exposure to large waves.
Sea Caves
This type of mechanical weathering is caused by humans digging deep pits into the earth to extract materials.
Mining
The slowing down and settling of rocky material
Deposition
This type of mechanical weathering occurs when different objects hit against one another.
Abrasion
This type of weathering occurs when iron mixes with water and oxygen to turn it a reddish brown color
Rust/Rusting
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
These objects that can form from heavy erosion are sometimes hidden by roads or thin layers of dirt.
Sinkholes
The carrying of broken down materials by wind, ice, or water
Erosion
This is what happens when rocks get hot from the weather and expand, over time this can cause cracks in rocks.
Expansion/Thermal Expansion
Humans cause chemical weathering by using/burning these, especially when using vehicles.
Fossil Fuels/Gas
These biologic organisms can break down rocks by both mechanical and chemical weathering
Plants/Roots
These sometimes act as temporary bridges over sinkholes until a heavy object goes over them that will cause them to break.
Roads
The breaking down of rocky materials with the use of physical forces.
Mechanical Weathering
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
This type of chemical weathering can occur from plants or other living organisms breaking down rocks.
Biological Weathering
This state in the United States is known to be the sinkhole capital of America
Michigan
These geographic features can be formed over a long period of time from deposition where rivers and oceans meet.
Deltas
Breaking down rocks by having them interact with oxygen, acids, or other chemicals.
Chemical Weathering
THis type of mechanical weathering only happens on roadways, most common on blacktop.
Potholes
This type of rock is heavily weathered by acid rain.
Limestone
This country has the worlds largest sinkhole that was undiscovered until 1994
China
This major natural disaster can occur when a large amount of rocks and debris get carried away all at once.
Landslide
