Science wave+glacier
waves and glaciers quiz
| Question | Answer |
|---|---|
| Moraine | A ridge, formed by a till deposited at the edge of a glacier |
| List the land features made by wave erosion | Sea caves, sea arches, sea stacks, and wave cut cliffs |
| Friction | Force that causes a wave to slow down and break when it reaches shallow water |
| Kettle lake | Small depression that forms when ice is left in glacial till |
| Drumlin | Long mound of till that is shaped in the direction of a glaciers flow |
| Barrier beach | Storm waves pile up sand above sea level |
| Sand bar | Long ridges of sand parallel to the shore |
| Spit | A beach that projects like a finger out into the water |
| Loess | Fine deposits that are valuable because it's fertile soil |
| Sand dunes | Deposits left by wind erosion, found on beaches, deserts, and can be different sizes |
| What is the difference between loess and sand dunes | Sand dune=deposit of wind blown sand Loess=particles made of clay and silt |
| Plucking | When a glacier picks up rocks |
| Ice-ages | Times when continental glaciers cover large parts of Earth's surface |
| How do glaciers move? | Glaciers move from gravity and ice melting |
| When do glaciers deposit sediment? | When glaciers melt |
| How do waves form? | Waves form from wind that blows across ocean surface |
| How do glaciers form? | Glaciers form when there are more snowfall then snow melt |
| What is the difference between continental glaciers and valley glaciers? | Valley glaciers=snow builds up high in mountain valley Continental glaciers=ice covers large islands or continents |
| Deflation | Process where wind picks up sediment and moves it |
| Till | Sediments deposited directly by a glacier |
| List the land Features made by glacier erosion | Arete, horns, cirques, glacial lakes, and u-shaped valleys |
