erosion

Question 1

erosion

Answer 1

In earth science, erosion is the action of surface processes that removes soil, rock, or dissolved material from one location on the Earth’s crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement

Question 2

weathering

Answer 2

Weathering is the deterioration of rocks, soils and minerals as well as wood and artificial materials through contact with water, atmospheric gases, and biological organisms.

Question 3

water cycle

Answer 3

The water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.

Question 4

evaporation

Answer 4

Evaporation is the process by which water changes from a liquid to a gas or vapor. Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor.

Question 5

condensation

Answer 5

Condensation is the change of the state of matter from the gas phase into the liquid phase, and is the reverse of vaporization. The word most often refers to the water cycle

Question 6

precipitation

Answer 6

In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravitational pull from clouds. The main forms of precipitation include drizzling, rain, sleet, snow, ice pellets, graupel and hail

Question 7

surface runoff

Answer 7

Surface runoff (also known as overland flow) 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 tributary, or affluent, is a stream or river that flows into a larger stream or main stem river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean.

Question 9

watershed

Answer 9

A watershed is the area of land where all of the water that drains off of it goes into the same place—a river, stream or lake. The smallest watersheds are the drainage areas for small streams and lakes.

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

deposition

Answer 11

A deposition in the law of the United States, or examination for discovery in the law of Canada, involves the taking of sworn, out-of-court oral testimony of a witness that may be reduced to a written transcript for later use in court or for discovery purposes.

Question 12

delta

Answer 12

Delta Air Lines, Inc., typically referred to as Delta, is one of the major airlines of the United States and a legacy carrier. One of the world’s oldest airlines in operation, Delta is headquartered in Atlanta, Georgia

Question 13

floodplain

Answer 13

A floodplain or flood plain or bottomlands is an area of land adjacent to a river which stretches from the banks of its channel to the base of the enclosing valley walls, and which experiences flooding during periods of high discharge

Question 14

water table

Answer 14

The water table is the upper surface of the zone of saturation. The zone of saturation is where the pores and fractures of the ground are saturated with water. It can also be simply explained as the depth below which the ground is saturated

Question 15

sewage treatment plants

Answer 15

Sewage treatment is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable for discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges

Question 16

septic tank

Answer 16

A septic tank is an underground chamber made of concrete, fiberglass, or plastic through which domestic wastewater flows for basic treatment. Settling and anaerobic processes reduce solids and organics, but the treatment efficiency is only moderate. Septic tank systems are a type of simple onsite sewage facility

Question 17

sea stacks

Answer 17

a very large rock in from of the ocean by caves

Question 18

sea arches

Answer 18

Sea arches are a spectacular phenomena created by Mother Nature with a little help from oceans. They are usually composed of a soft rock that eroded over millions of years as waves hit land, carving caves and tunnels in the rock.

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. Sea caves are found throughout the world, actively forming along present coastlines and as relict sea caves on former coastlines.

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 …

Question 21

headlands

Answer 21

A headland, also known as a head, is a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water. It is a type of promontory.

Question 22

beach

Answer 22

a pebbly or sandy shore, especially by the ocean between high- and low-water marks.

Question 23

glacier

Answer 23

A glacier is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries

Question 24

glacial drift

Answer 24

Glacial drift. A general term applied to all rock material (clay, silt, sand, gravel, boulders) transported by a glacier and deposited directly by or from the ice, or by running water emanating from a glacier. This category is also used for Glacial sediment.

Question 25

till

Answer 25

Till or glacial till is unsorted glacial sediment. Till is derived from the erosion and entrainment of material by the moving ice of a glacier. It is deposited some distance down-ice to form terminal, lateral, medial and ground moraines

Question 26

stratified drift

Answer 26

STRATIFIED DRIFT means predominantly unconsolidated, sorted sediment composed of layers of sand, gravel, silt or clay deposited by meltwaters from glaciers.
