Question | Answer |

A river starts as a steep channel in the mountains. It then leaves the mountains and enters a flatter area of land. It meanders across a plain and then enters the ocean. Which of the following actions causes the deposition of sand at a delta? | river water slowing as it enters the ocean |
Emily used a tray filled with dirt as a model of a stream. Emily poured water into the top of the tray and observed how much erosion happened. Emily then increased the slope of the tray and repeated the experiment. | The speed of the water and the amount of erosion would increase. |
What dœs GIS stand for? | Geographic Information System |
Canyons, caverns, channels, and valleys all form because of erosion by water. Which landform listed is mainly formed because of erosion by groundwater? | an underground cavern |
Look at the topographic map below. Assume the distance of each route is the same. Which route would be the easiest for a hiker to climb to the top? | B |
Which statement about floodplains is true? | Floodplains are good places to grow crops. |
Landslides, rockfalls, and mudslides are responsible for both erosion and deposition. What force is mainly responsible for the erosion and deposition that happens in landslides, rockfalls, and mudslides? | gravity |
In places where there is loose sediment and strong wind, the wind can pick up the sediment and carry it. When the wind slows, it deposits the sediment. Which type of sediment will be dropped first as the wind slows? | the heaviest |
If the scale on a map reads 1:100,000, what dœs this mean? | 1 cm on the map = 100,000 cm on Earth’s surface |
Look at the topographic map below. Assuming the elevations are in feet, what is a good estimate of the relief? | about 3600 ft |
GIS enables users to combine map and image layers. If a biologist were interested in the relationship between the slope of the land and the type of vegetation, which layers would be most helpful? | aerial image and topographic map |
