| Question | Answer |
|---|---|
| When waves crash onto the beach at an angle a longshore drift is created along the | Coastline |
| The process where wind picks up sediment and moves it is called | Deflation |
| What is till? | The mixture of sediments that a glacier directly deposits onto a surface is called till. |
| List the land features that can be made by glacial erosion part (1) | Cirque- A bowl-shaped hollow eroded by a glacier (on a mountain) Arete- a sharp ridge separating two cirques Glacial lakes- Large lakes in basins eroded by plucking and abrasions |
| List the land features that can be made by glacial erosion part (2) | Horn |
| Define the following land features made by glacial deposition. Part (1) | Moraine Moraine- Where a glacier deposits mounds of ridges of till made up of Drumlin Drumlin- Ice sliding over a moraine may shape it into a drumlin. A drumlin is a long mound of till smoothed in the direction of the glaciers flow. |
| Define the following land features made by glacial deposition Part(2) | Kettle Lake Kettle lake- Forms when a depression left in till by melting ice fills with water |
| What force causes a wave to slow down and break when it reaches shallow water? | The friction between the wave and the bottom |
| What land features are made from wave erosion? | Sea arch Sea cave Wave-cut cliff Define the following land features made by wave deposition. |
| Define the following land features made by wave deposition. | Barrier Beach Forms when storm waves pile up sand above sea level. hey are similar to sand bars. Sandbar Long ridges of sand parallel to the shore Spit A beach that projects like a finger out to the water. |
| What is the difference between a sand dune and a loess? | Sand dune- a deposit of wind-blown sand Loess- is a fine wind deposited sediment. Difference= sand dune is sand loess is fine wind deposited sediment |
| What is mass movement and what causes it? | Mass movement is any process when sediment is moved down hill. Gravity causes mass movement. |
| What are the four types of mass movement? Explain each type. | Landslide- Rock and soil quickly move down a hill. Mudslide- When a mix of rock, soil, and water move downhill. Slump- A big piece of rock suddenly falls down a slump Creep- The extremely slow downhill movement of rock and soil. |
| What is the material moved by erosion called? | Sediment |
| What is deposition? | Sediment laid down by erosion. |
| What is the major agent that has shaped Earth’s surface? | What is the major agent that has shaped Earth’s surface? Water |
| What is runoff? List and explain the five factors that control the amount of runoff. Part (1) | All the remaining water on earth's surface is runoff. Amount of rain an area receives. The more plants the less runoff because plants absorb runoff The type of soil. Some soils absorb water more than others. |
| What is runoff? List and explain the five factors that control the amount of runoff (Part 2) | Shape of land. Steeper = more runoff How people use the land. Parking lots absorb no rain. |
| Define the following- Rill, gully, stream and river. | Rills- Tiny grooves in the soil Gullys- A large groove or channel in the soil Stream- A channel in which water is continuously flowing down a slope River- A large stream |
| What land features are created by water erosion? Explain each one. Part(1) | Valley The big deep are in between rocks Waterfall- When softer rock and harder rock are together and water is flowing over it the soft rock i weathered making a steep cliff. Floodplain- The flat wide area along a river |
| What land features are created by water erosion? Explain each one. Part(2) | Meander- A loop like bend in the river. OXbow lake- A cut off meander |
| What features are made by deposits from rivers? Explain each one. | Alluvial Fan- A wide sloping deposit of sediment formed where a stream where a stream leaves a mountain range. And delta- Soil deposited where a river flows into a ocean or lake |
| Explain what Karst Topography is. | A landscape marked by caves and sinkholes |
| What two features can form from groundwater deposition? Explain each one | Stalactite- A deposit of calcite hanging from the ceiling of a cave Stalagmite- A deposit of calcite hanging like icicles from the bottom of a cave. |
| What features can form from groundwater erosion? | Stalactite- A deposit of calcite hanging from the ceiling of a cave Stalagmite- A deposit of calcite hanging like icicles from the bottom of a cave. |
| What is a longshore drift? | The process in wich Repeated waves hit the beach and sediment moves down the beach with the current. |
| How do waves form | The wind that blows across the ocean. |
| Define glacier | Any large mass of ie that slowly moves over land |
| What are the two types of glaciers? | Valley glacier and continental glacier. |
| What factors determine how fast a rivers flow is? | The slope, the Volume of flow, and the stream bed shape |
| what is friction? | the force that opposes the motion of one surface as it moves across another surface. |
| What is abrasion? | The wearing away of rock by a grinding action |
| What is a tributary? | Is a stream that flows into a larger stream. |
