|---|---|---|---|---|---|
| Define Beaches | Shorelines made up of sand if on the east coats made of rock if on the west coast.
the waves wear away land and expose rocky shores
Tides bring in the sediment , shells and sand to the beaches.
🗑
|
||||
| Define Sandunes | Mounts of sand
🗑
|
||||
| Define Barrier Island | Pieces of land the are surround by water on all sides.
They are used to protect the inland during storms.
🗑
|
||||
| Define Sediment | Weathered rock and other materials carried by water and wind
🗑
|
||||
| Define Inlets | Are water filled spaces between barrier islands. Inlets shapes change due to ocean currents, and storms.
🗑
|
||||
| Define Salt Marshes | Are found within estuaries the collect excess water during storms. Filters ocean water.
🗑
|
||||
| Define Water Movements | 3 main ways water moves is through
Tides
Currents
and or Waves
🗑
|
||||
| Define Currents | Ongoing movement of ocean water TYPES; cold surface and warm surface The Gulf Stream is responsible for moving it from the near equator
wind moving across the surface of the water creates currents
🗑
|
||||
| Define Currents | Caused by Earth's rotation, it moves in only one direction
🗑
|
||||
| Define Waves | Repeated Movement of water Peak- Crest lowest part- trough breaker is when the top of the wave curls Giant sea waves are called tusnamis
🗑
|
||||
| Define Tides | Tides -changes of the level of water at the ocean shore regular rise and fall of waters , CAUSED- by the moon's gravity they rise and fall about twice aday
🗑
|
||||
| Define Spring Tides | when the sun and the moon line up pulls in the same direction and causes lower low tides and higher high tides occurs only on full moons
🗑
|
||||
| Define Neap Tides | when the sun and the moon line up and the pulls partly cancel out each other and only occurs during first and third moon
🗑
|
||||
| Describe Hurricanes and other large storms | Hurricanes and other large storms can cause massive construction or destruction to barrier islands, estuaries, and inlets because they produce high waves , storm surges, and heavy wind.
🗑
|
||||
| Describe How do waves, currents, tides, and storms affect the ocean shore zone | can change because of the force of the and strength of each wave. Erosion and sand deposition change according to location. of ocean currents, weather condition, tides. Landforms and beach erosion form marine terraces along the shoreline.
