Mechanical Weathering
What are tiny pieces of rock that are mechanically weathered called?
Sediments
Name on example of chemical erosion
Oxidation, acid rain, Lichens, moss, and other plants
Name 2 agents of erosion
Wind, Water, Gravity, Glaciers
A body of water that has no outlet to an ocean is known as a
Lake
Which landform would you most likely find at the end of a river?
Delta
Define mechanical weathering
The physical break down of rocks in to smaller pieces
Name 1 form of evidence that suggested chemical weathering has occurred
Color change, rust, dissolved rock
This landform is often created as a result of wind erosion
Sand Dunes
What type of landform is Florida known as
Pennisula
How is frost wedging different than frost heaving?
Frost wedging splits rock apart while frost heaving gets underneath and forces upward
How is chemical weathering different than mechanical weathering
Chemical weathering changes the chemicals that make up a rock while mechanical physically breaks rock in to smaller pieces
Erosion by gravity is better known as ____________
Mass movement or Mass wasting
How are an island and an archipelago related to each other?
an archipelago is a long chain of islands like the Florida Keys
Name 2 specific landforms that can be found in Florida
Coastlines- siesta key, Cocoa Beach
Rivers- Indian river, Peace River
Iron Mountain
Lake Okechobee
Apilachicola River Delta
Why would you find a smooth rock at the bottom of a river?
How is acid rain created?
Carbon is released in to the atmosphere by burning fossil fuels. This makes rainfall more acidic than normal
Give an example of a way that erosion is beneficial
Answers will vary. Possible options include depositing fertile soil along river banks and building up sand dunes to protect beaches from further erosion
Define Plateau
An elevated piece of land with a flattened top
Why are mountain summits usually pointed?
Strong wind, rain, and ice weather and erode rocky materials that are then carried down due to gravity.
How are living things responsible for mechanical weathering?
Animals can break up rocks as they burrow while roots can grow and push through rocks
Explain why the Statue of liberty is green
A combination of oxygen in the air and sea water splashing against it
Which two factors can increase the speed of erosion in an area
Slope of a hill and amount of rainfall
Why does Florida have a major sinkhole problem?
Florida's base is made of limestone which easily dissolves due to excessive rainfall and underground water storage
How are canyons different than valleys?
Canyons have steep slopes carved by fast moving stream erosion, while valleys have gentle hills usually formed from slower moving water
