A sand dune is formed by (erosion or deposition)
deposition
What is a delta?
where sediment is dumped off at the end of a river/stream. Formed by deposition
After a mountain is formed it begins to ________
Weather
What is the difference between erosion and deposition?
Erosion is the movement of rocks and deposition is when the rock stops moving
When wind picks up sand and scrapes another rock this is
abrasion due to wind erosion
Characteristics of landforms created by erosion are
tall and jagged
A barrier island helps _________ _________
prevent erosion
Weathered rocks from the mountain then begin to move down the mountain due to gravity and are thus ____________ ________
Eroded away
Rocks grinding against other rocks is an example of _________ weathering
Plants growing through a rock is an example of _____________ weathering
Acid rain is an example of __________ weathering
Physical, Biological, and chemical
What can protect from erosion?
Geographical and biological barriers

What is the difference between a sand dune and a desert loess?
+100 what do they have in common (I am looking for something specific)
A desert loess is made of clay and silt
a sand dune is made of sand
Bonus: they are made by wind deposition
When the rocks reach the bottom of the mountain and are no longer moving, they are said to be __________
Deposited
What key molecule causes oxidation?
oxygen
_______ are common plants in Florida that grow along the coast and protect islands from erosion
mangroves
Explain the formation of a sinkhole
Water moves through the surface and passes through carbonate rock (limestone). As it passes through limestone, the water becomes more acidic. The water is acidic enough that it is able to eat through rock and create a void beneath the surface that grows over time, eventually causing the surface to collapse inwards.
What determines the angle of the incoming wave of a longshore current?
The prevailing wind
What is required for the rocks that are deposited to form a new rock?
Heat and pressure
