Weathering
What is the definition of Weathering?
What is the definition of Erosion?
The movement of weathered material from one place to another.
What is the definition of Deposition?
The laying down or settling of eroded material.
What state is Long Island found In?
New York
Name one form of Mechanical weathering
Abrasion, Freeze/Thaw, Thermal Stress, Plant Roots, Animal Activity
How is sediment and soil formed?
The breaking down of larger rocks and rock fragments through weathering processes
Is erosion a constructive (builds up), or a destructive (breaks down) force?
Destructive (breaks down)
Is deposition a constructive (builds up), or a destructive (breaks down) force?
Constructive (builds up)
What chemical weathering process does long Island experience since it’s so close to New York City?
Acid Rain
What agent of deposition causes sand dunes to form?
Wind
As sediment particles get smaller, what happens to surface area?
It increases, which also increases the rate of weathering.
What are some defining characteristics of erosional landforms?
Jagged and tall, built from several layers of rock.
What are some defining characteristics of Depositional landforms?
Flat and Low-lying.
Why is Long Island’s North Shore rocky, while it’s South Shore is sandy?
Increased weathering (Abrasion) from the Atlantic Ocean
What process caused the statue of liberty to change from a Copper color to a Green color?
Oxidation
Why does the freezing and thawing of water cause weathering?
What agent of erosion and deposition is constantly acting on everything on Earth?
Gravity
What comes in many forms and is considered the greatest agent of erosion and deposition on Earth?
Water
What caused Long Island’s Iconic North and South Forks to form?
Glaciers (Deposition of Glacial Sediment)
True or False: All rainwater is slightly acidic?
True
What are three types of CHEMICAL weathering?
Oxidation/Acid Rain/Hydrolysis/Carbonation/Biological Weathering
What are three Erosional Landforms?
Hoodoos, Sea Cliffs, Arches, Stacks, U-Shaped Valleys
What are three depositional landforms?
Deserts, Spits, Sandbars, Barrier Islands, Tombolos, River Deltas, Alluvial Fans
What town can you find large glacier deposits on Long Island?
