| Question | Answer |
|---|---|
| delta | the flat triangular-shaped plain formed when a river empties into the ocean |
| erosion | the gradual wearing away and REMOVING of rock material by forces such as moving water, wind, and moving ice |
| sediments | sand,soil,and rock carried by water, wind, or ice |
| river system | a river and the waterways such as brooks, streams, and rivers that drain into it |
| weathering | the physical and chemical processes by which rock is BROKEN down into smaller pieces |
| headland | a nature made piece of land that usually extends out into the water and usually slows down the flow of water that passes it. |
| bay | part of a sea or lake extending into the land |
| jetty | a human made structure extended into a sea lake, or river to influence the current or tide or to protect a harbor |
| shoreline | the line that forms where the water meets the land in a river, lake or ocean |
| sand dune | a mound, hill, or ridge of sand formed by the wind |
| glacier | a huge mass of very slow-moving ice that forms over land |
| moraine | materials such as large rocks that is carried by glaciers |
| What human machine is a glacier often compared to? | bulldozer |
| What part of a plant causes weathering of rocks? | roots |
| What is the main force that makes glaciers move? | gravity |
| What is the difference between weathering and erosion? | Weathering is breaking apart rocks into sediment. Erosion is carrying away the sediment through wind, water, or ice. |
| What happens to the speed of water when a river reaches the mouth of the ocean? | The river loses energy and slows down. |
| What most likely caused the grooves on Kelly's Island in Lake Erie? | Glacier |
| Describe the term "frost heaves" and what causes them? | Frost heaves is when the ground is frozen and thrust upward. It is caused by freezing and thawing of water in the ground. |
| What natural processes slowly wears away a stone sculpture? | Rain and wind |
| Be able to restate a question and completely answer about what remains after a glacier has melted. | Check pg A23 and A24 in your textbook |
| Be able to identify an advantage and disadvantage of growing crops in flood plains and deltas. |
