What land forms are made by groundwater erosion?
VOCABULARY
What coastal landforms are made by erosion?
100
What is sediment made up of?
Sediment is made up of tiny grains of broken-down rock.
100
What is a shoreline?
A shoreline is the place where land and a body of water meet. Ocean water along a shoreline moves differently than river water moves near a shoreline.
100
What would happen if the level of groundwater in a cave dropped below the level of the cave itself?
The roof would collapse and a sinkhole would form.
100
What is the term for the process by which sediment and other materials are moved from one place to another?
Erosion
100
Wave Erosion produces a variety of features along a shoreline. The rate at which rock erodes depends on what?
It depends on the hardness of the rock and the energy of the waves.
200
Where does the eroded materials in streams come from?
Eroded materials in streams come from the stream's own bed and banks or from materials carried to the stream by rain water runoff.
200
What is a headland?
A headland is a piece of land that projects into the water.
200
True or false? Caves are formed only by Erosion
False
200
What is the term for the process by which eroded material is dropped?
Deposition
200
Waves erode and under cut rocks to make steep slopes and waves strike the cliff's base wearing away the rock. This makes what?
A Sea Cliff
300
What role does Gravity have in changing Earth's surface?
Gravity has a role to cause water to flow and rocks to fall downhill.
300
What is a longshore current? & What is this caused by?
A longshore current is when water travels almost parallel to the shoreline, very near shore. These are caused by waves hitting the shore at an angle.
300
What causes stalacitites and stalagmites?
Water dripping from the cracks in a cave ceiling
300
What is the water that is located within the rocks below earths surface called?
Ground water
300
How are sea caves made?
Waves can cut deeply into the cracks and form large holes.
400
How does Erosion change Earth's surface?
Erosion changes Earth's surface by causing the streams to widen and deepen, where Erosion is the process by which sediment and other materials are moved from one place to another.
400
How do waves shape a shoreline?
Waves shape a shoreline by slowing down as they approach the shoreline. The slow waves bend toward the headlands, which concentrates the waves' energy. A huge amount of energy is released when waves crash into headlands, causing the land to erode.
400
___________ can cause erosion by dissolving rock.
slightly acidic groundwater
400
What is the term for an area of shorline that is made up of material deposited by waves and currents?
Beach
400
Sea caves erode more and more, then become a sea arch. When the sea arch collapse it becomes a __________?
Sea arch
500
How does deposition change Earth's surface? & When does it mostly occur?
Deposition changes Earth's surface by/when eroded material is dropped. This only occurs when gravity's downward pull on sediment is greater than the push of flowing water or wind.This usually happens when the water or wind slows down.
500
How do currents shape a shoreline?
Currents shape a shoreline when the waves push sand in a same angled direction in which they break. But the return water flow moves sand directly away from the beach. As sand moves down the beach, the up current end of the beach is eroded away, while the down current end of the beach is built up.
500
True or false? large underground caves are formed over thousands of years.
True
500
What is the popular term for a long narrow island, usually made of sand, that forms parallel to the shorline a short distance off shore?
Barrier Island
500
Many ________ __________ are made by differences in rock hardness
Shoreline/Features
