| Question | Answer |
|---|---|
| explain how a glacier picks up rocks. | the glacier crushes the rock and overtime, the rock freezes into the glacier |
| when rocks and soil move very slowly down a hill, it is called a _______________. | creep |
| a deposit that hangs down from the roof of a cave is called a ____________. | stalactite |
| where till is dropped along the edge of a glacier, it forms a ______________. | moraine |
| a beach that sticks out into the water like a finger is called a _________. | spit |
| tiny pieces of sediment that are dropped by the wind are ________________. | loess |
| what are the five agents of erosion? | water, wind, waves, gravity, and glaciers |
| during longshore drift, sand is carried _______ ___ __________. | down the beach |
| what is responsible for mass movement? | gravity |
| the major agent of erosion is ______. | water |
| ________ scratch the land as it moves. | glaciers |
| name the feature that forms sand dunes and loess deposits. | wind erosion and deposition |
| name the feature that forms features like sea arches, spits, and sandbars. | waves |
| how does moving water cause erosion? | as water moves across the land, it picks up and carries particles of sediment with it. |
| how do glaciers cause erosion and deposition? | the movement of glaciers break and carry frozen rock with it until it melts. |
| how do waves cause erosion and deposition? | the wave hits the seafloor and picks up sediment as it goes and when the wave hits the surface or slows down, the sediment is deposited. |
| how does wind cause erosion and deposition? | as the wind blows, it picks up pieces of sediment and carries it with it. the sediment is deposited when wind hits and obstacle or slows down. |
| how does erosion and deposition shape caves? | the chemical reaction between carbonic acid and limestone wear away on parts of a landform, causing a cavern (cave) to form. |
| the process by which natural forces move weathered rock from one place to another | erosion |
| the process of erosion moves material called ____________. | sediment |
| when the gents of erosion lay down (deposit) sediment | deposition |
| the force that pulls objects downward | gravity |
| any one of the several processes that move sediment downhill | mass movement |
| as water moves over the land, it carries particles with it. this moving water is called ___________. | runoff |
| as runoff travels, it forms tiny grooves in the soil called _____. | rills |
| a large groove or channel in the soil that carries runoff after a rainstorm | gully |
| a channel along which water is continually flowing down a slope. | stream |
| a stream or river that flows that flows into a larger river. | tributary |
| the flat, wide area of land along a river | flood plain |
| a looplike bend in the course of a river | meander |
| a meander that has been cut off from the river. | oxbow lake |
| sediment deposited where a river floes into an ocean or lake builds up a landform called a ________. | delta |
| a wide sloping deposit of sediment formed where a stream leaves a mountain range | alluvial fan |
| the term geologists use for this underground water | groundwater |
| a deposit that hangs from the ceiling of a cave | stalactite |
| slow dripping builds up a cone shaped __________ (made on the floor of a cave) | stalagmite |
| if the roof of a cave collapses because of the erosion of underlying limestone, the result is a depression in the land . this landscape is called ________ ________________ | karst topography |
| any large mass of ice that moves slowly over the land | glacier |
| a glacier that covers much of a continent or island | |
| ice ages | |
| a long, narrow glacier that forms when snow and ice build up high in a mountain valley | valley glacier |
| as a glacier flows over the land, it picks up rocks in a process called ___________. | plucking |
| the mixture of sediments that a glacier deposits directly on the surface is called ____. | till |
| the till deposited at the edge of a glacier forms a ridge called a ______________. | moraine |
| a small depression that forms when a chunk of ice is left in a glacial till | kettle |
| a part of the shore that sticks out into the ocean. | headland |
| an are of wave-washed sediment along a coast. | beach |
| as waves repeatedly hit the beach, some of the beach sediment moves down the beach with the current, in process called ____________________. | longshore drift |
| a beach that projects outwards like a finger. (effect of longshore drift) | spit |
| the process by which wind removes surface materials | deflation |
| when the wind hits an obstacle, the result is usually a deposit of windblown sand called a sand dune | sand dune |
| sediment that is smaller than sand, such as particles of clay and silt, is dropped far from it's source in large deposits. this windblown sediment is called __________. | loess |
