Weathering and Erosi
Chap 8 and 9
| Question | Answer |
|---|---|
| The process that wears away surface materials and moves them from one location to another. | Erosion |
| A system of creeks, streams, and rivers that connect to carry water to the ocean. | Drainage basin |
| A well that doesn't require pumping | Artesian well |
| A hot spring that erupts periodically, shooting hot water and steam into the air. | Geyser |
| One of the two tyes of river deposition that usually forms as a river flows into the ocean or gulf. | Delta |
| Shape of young river-created valleys. | V-shape |
| A moving mass of snow and ice | Glacier |
| Mature and old rivers both have these flat areas between the valley walls resuting from back and forth erosion. | Flood plain |
| The upper boundary of the zone of saturation in an aquifer. | Water table |
| These are calcite formations that hang from the cavern ceiling. | Stalactites |
| Rock material left behind by a retreating glacier. | Till |
| This is the flow of water caused by the ground being saturated with water. | Runoff |
| Shape of glacier-created valleys. | U-Shape |
| The type of glacier that covers both Antarctica and Greenland. | Continental |
| A layer of permeable rock that lets water move freely. | Aquifer |
| Type of acid that erodes limestone to form a cavern over a long period of time | Carbonic |
| Thick mixture of water and sediments flowing downhill. | Mudflow |
| Type of glacier found in high mountain areas where the temperature is below freezing. | Valley glacier |
| Layer of soil that is important for plant growth. | Topsoil |
| Ridgelike rock material carried by a glacier. | Moraine |
| What are some factors that affect runoff? | Amount of rainfall, slope of the land, amount of vegetation |
| A bend in a river formed by erosion. | Meander |
| Name some causes of mechanical weathering. | Ice, burrowing animals, tree roots |
| What are the three classifications for sedimentary rocks? | Detrital, chemical, and organic |
| A period of mass global glaciation. The most recent occured 18,000 years ago | Ice age |
| Rock fragments, mineral grains,and bits of plants and animal remains moved by wind, water, ice or gravity. | Sediments |
| A mixture of weathered rock, mineral fragments, decayed organic matter, water, and air | Soil |
| This type of weathering changes the chemical composition of the rock. | Chemical weathering |
| A mound of sediments drifted by the wind. | Dune |
| What are some factors that affect the formation of soil? | Climate, type of rock, slope of the land |
| The dark-colored organic matter found in soil | Humus |
| Ice picking up pieces of rock | Plucking |
| Loess, dunes and moraines are examples | Deposition |
| Material that is deposited by meltwater beyond the end of a glacier. | Outwash |
| Any type of erosion that happens as gravity moves material down slope. | Mass movement |
| A large mass of ice and snow moving on land under its own weight. | Glacier |
| Water that soaks into the ground and collects in empty spaces and pores. | Groundwater |
| Rock that has spaces that are connected so that water can pass through. | Permeable |
| When water cannot pass through rock. | Impermeable |
| A layer of permeable rock that lets water pass through. | Aquifer |
| When the water table is close to Earth's surface water can flow out through a | Spring |
