Erosion

Question 1

erosion

Answer 1

the process by which wind, water, ice, or gravity transports soil and sediment from one location to another

Question 2

weathering

Answer 2

the process by which rock materials are broken down by the action of physical or chemical processes

Question 3

water cycle

Answer 3

the continuous movement of water from the ocean to the atmosphere to the land and back to the ocean

Question 4

evaporation

Answer 4

Evaporation is a type of vaporization of a liquid that occurs from the surface of a liquid into a gaseous phase that is not saturated with the evaporating substance

Question 5

condensation

Answer 5

change of state from gas to a liquid

Question 6

precipitation

Answer 6

water falling from the clouds to the earth surface

Question 7

percolation

Answer 7

the process of a liquid slowly passing through a filter.

Question 8

runoff

Answer 8

Surface runoff is the flow of water that occurs when excess stormwater, meltwater, or other sources flows over the Earth’s surface

Question 9

tributary

Answer 9

a stream that flows into a lake or into larger stream

Question 10

watershed

Answer 10

area of land that is drained by a water system

Question 11

continental divide

Answer 11

a drainage divide on a continent such that the drainage basin on one side of the divide feeds into one ocean or sea, and the basin on the other side either feeds into a different ocean or sea, or else is endorheic, not connected to the open sea.

Question 12

deposition

Answer 12

the process in which material is laid down

Question 13

delta

Answer 13

a fan shaped mass of material deposited at the mouth of a stream

Question 14

alluvial fan

Answer 14

a fan shaped mass of material deposited by a stream when the slope of the land decreases sharply

Question 15

floodplain

Answer 15

an area along a river that forms from sediments deposited when the river overflows its banks

Question 16

water table

Answer 16

the upper surface of underground water; the upper boundary of the zone of saturation

Question 17

sewage treatment plants

Answer 17

a facility that cleans the waste materials found in water that comes from sewers or drains

Question 18

septic tank

Answer 18

a tank that separates solid waste from liquids and that has bacteria that break down solid waste

Question 19

sea stacks

Answer 19

a column of rock standing in the sea, remaining after erosion of cliffs

Question 20

sea arches

Answer 20

a natural opening eroded out of a cliff face by marine processes. Some arches appear to have developed from surge channels, which are created by wave refraction causing the focussing of wave fronts on the side of a headland

Question 21

sea caves

Answer 21

formed primarily by the wave action of the sea. The primary process involved is erosion

Question 22

wave-cut terraces

Answer 22

a shallow-water shelf inclining gently away from the base of an eroded sea cliff

Question 23

headlands

Answer 23

a narrow piece of land that projects from a coastline into the sea

Question 24

beach

Answer 24

an area of the shoreline made up of material deposited by waves

Question 25

glacier

Answer 25

a large mass of moving ice

Question 26

glacial drift

Answer 26

the rock material carried and deposited by glaciers

Question 27

till

Answer 27

unsorted rock material that is deposited directly y a melting glacier

Question 28

stratified drift

Answer 28

a glacial deposit that has been sorted and layered by the action of streams or melting water
