erosion

Question 1

Erosion

Answer 1

the process of eroding or being eroded by wind, water, or other natural agents.

Question 2

Weathering

Answer 2

the process of wearing or being worn by long exposure to the atmosphere.

Question 3

water cycle

Answer 3

the cycle of processes by which water circulates between the earth’s oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.

Question 4

Evaporation

Answer 4

the process of turning from liquid into vapor.

Question 5

Condensation

Answer 5

water which collects as droplets on a cold surface when humid air is in contact with it.

Question 6

precipitation

Answer 6

Precipitation is any liquid or frozen water that forms in the atmosphere and falls back to the Earth.

Question 7

surface runoff

Answer 7

Surface runoff is the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil.

Question 8

tributary

Answer 8

a river or stream flowing into a larger river or lake.

Question 9

watershed

Answer 9

an area or ridge of land that separates waters flowing to different rivers, basins, or seas.

Question 10

continental divide

Answer 10

A continental divide is 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 11

deposistion

Answer 11

a formal statement that someone who has promised to tell the truth makes so that the statement can be used in court.

Question 12

delta

Answer 12

Landform

Question 13

floodpain

Answer 13

an area of low-lying ground adjacent to a river, formed mainly of river sediments and subject to flooding.

Question 14

water table

Answer 14

the level below which the ground is saturated with water.

Question 15

sewage treatment plants

Answer 15

The treatment of sewage is part of the field of sanitation

Question 16

septic tank

Answer 16

a tank, typically underground, in which sewage is collected and allowed to decompose through bacterial activity before draining by means of a leaching field.

Question 17

sea stacks

Answer 17

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

Question 18

sea arches

Answer 18

Sea arches. Another spectacular type of erosional landform is the sea arch, which forms as the result of different rates of erosion typically due to the varied resistance of bedrock.

Question 19

sea caves

Answer 19

A sea cave, also known as a littoral cave, is a type of cave formed primarily by the wave action of the sea. The primary process involved is erosion.

Question 20

wave-cut Terraces

Answer 20

A wave-cut platform, shore platform, coastal bench, or wave-cut cliff is the narrow flat area often found at the base of a sea cliff or along the shoreline of a lake, bay, or sea that was created by erosion.

Question 21

Headlands

Answer 21

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

Question 22

Beach

Answer 22

a strip of land covered with sand, pebbles, or small stones at the edge of a body of water, especially by the ocean between high- and low-water marks.

Question 23

glacier

Answer 23

a slowly moving mass or river of ice formed by the accumulation and compaction of snow on mountains or near the poles.

Question 24

glacial drift

Answer 24

In geology, drift is a name for all sediment transported by a glacier and deposited directly by or from the ice, or by glacial meltwater.

Question 25

till

Answer 25

the net soil translocation on the hillslope due to tillage operations, expressed in units of volume, mass, or depth per unit width of tillage.

Question 26

stratified drift

Answer 26

predominantly sorted sediment laid down by or in meltwater from glaciers and includes sand, gravel, silt, and clay arranged in layers.
