|
Weathering |
Questions Below |
|
|
What is it? |
The breaking down of rocks and sediment over time |
|
|
Erosion |
The movement of weathered down rocks or sediment |
|
|
Long shore drift and how it effects the beach |
The main way that sediment is moved and deposited along a coastline. |
|
|
Long shore drift (Definition,Diagram) |
When waves that hit the beach at an angle and carry sediment up the beach at an angle (swash). When the water washes back the sediment is carried back down the beach (backwash). Individual particles are moved along the beach in a zig zag pattern |
|
|
Deposition |
the laying down of sediment that has been carried by erosion |
|
|
3 types of weathering (definition,example) |
Mechanical-Involves breaking of larger rocks into smaller rocks (water seeping into a rock, water freezes, expands and causes the rock to crack making it easy to break into smaller pieces) Chemical-Involves changes in the minerals of the rock or on the surface of the rock that make the rock change color or shape (some rocks contain minerals like iron, so when that iron is exposed to oxygen it causes the rock to soften,making it easier to break apart into smaller pieces). Biological- involves larger rocks breaking into smaller pieces which is caused by plants animals or other living organisms. (A plants roots find their way into the opening of a rock, eventually as that plant grows the rock will start to crack open until it breaks apart into smaller pieces). |

Types of Coastal Zones (Tide Pools) |
Physical characteristics: -They have shallow depths and assist in the flow of tides. -Tide pools are very rocky formations. -They form in the intertidal zone long rocky coastlines where the ocean meets the land. Biological characteristics: Tidal pools provide a home for many organisms such as sea stars, mussels and clams Inhabitants deal with a frequently changing environment. Such as: fluctuations in water temperature, salinity, and oxygen content. |
