2 basic ingredients neccessary to make sand? | Rock and Energy |
What is a shoreline? | A place where a body of water meets land. |
What determines the size of the wave? | How hard and long the wind is blowing. |
What is a wave train? | Waves that move in groups |
How do waves break down rocks into sand? | They crash into the rock many times until it turns into sand |
5 landforms produced by wave erosion | Sea stack, sea cave, sea arch, headland, wave-cut terrace |
Why are large waves mor capable of removing large chuncks of rock form a shoreline than normal waves can? | MORE ENERGY!!!!!! |
What is a beach? | An area of the shorling made up of materials deposited by waves. |
Are all beaches the same? Why? | No, because all beaches are made of different material |
Where does the beach material come from? | The material that the waves bring up from the sea or from the enviroment around the shoreline |
What is a longshore current? | A water current that mobes water in a zig-zag pattern along the beach |
2 examples of landforms that are created by longshore currents in open water | Barrier spit and sandbar |
What areas are shaped most dramatically by wind and why? | Deserts and coastlines beacause they have little plant coverage to anchor the fine, loose rock material |
What is saltation? | Skipping and bouncing of sand-sized particles in the wind |
What is deflation? | Removing sand from an area by the wind |
Desert pavement is caused by what? | Deflation |
The grinding and wearing down of rock surfaces by other rock or sand particles is called___________. | Abrasion |
Where does abrasion commonly occur? | Areas where there are strong winds, loose sand, and soft rock. |
What is loess? | Very fine material deposited by the wind. |
Where did many of the loess deposits come from and how did they travel so far? | They came from the glacial sources from the Ice Age and they traveled so far by the wind becuase it carries the fine-grained material much higher and farther than regular sand. |
What are dunes? | Mounds of sand made by one staionary object. |
