Chapter Two World Geography

Front 1

oceans, lakes, rivers& other bodies of water make uo a part of the earth.

Back 1

hydrosphere

Front 2

land make up a part of earth, 30% of water.

Back 2

lithosphere

Front 3

the part of earth that supports the earth.

Back 3

biosphere

Front 4

an underwater extention of the coastal plain.

Back 4

continental shelf

Front 5

at the very center of the planet is a super-hot but soild inner.

Back 5

core

Front 6

next to outter core a thick layer of hot, dense rock.

Back 6

mantle

Front 7

outter layer, 2 miles-75 miles

Back 7

crust

Front 8

theory continents were once jioned&slowly drifted apart.

Back 8

contiental drift

Front 9

term refers to all of the physical process that create many of the earths physical process.

Back 9

plate tectonics

Front 10

push up mountains,creats volcanoes,&produce earth quakes, this is formed in cracks.

Back 10

magma

Front 11

the heavier sea plate dives beneth the lighter continental plate.

Back 11

subduction

Front 12

pieces of the earths crust come together slowly as the sea plate slides under the continental plate.

Back 12

accretion

Front 13

sea plants also can pull a part in a process know as this

Back 13

spreading

Front 14

this forms/bends.

Back 14

fold

Front 15

cracks in earths crust

Back 15

fault

Front 16

folded land can't be bent

Back 16

faulting

Front 17

breaks down rocks&is a part of condensation,percipitaon&evaporation

Back 17

weathering

Front 18

wears away the earths surface by wind, glaciers,&moving water.

Back 18

erosion

Front 19

another cause of erosion or large bodies of ice

Back 19

glaciers

Front 20

large piles of rocks&debris

Back 20

morquine

Front 21

movement of water

Back 21

water cycle

Front 22

the changing of liquid water into vapor, or gas

Back 22

evaporation

Front 23

when warm air cools, it cant retain all of its water vapor, so the excess water vapor changes in to liquid water.

Back 23

condensation

Front 24

rain, snow, or sleet, depending on the air temp.&wind conditions

Back 24

percipitation

Front 25

worlds increasing need for freshwater, such as turning ocean water into freshwater by removing the salt in a process.

Back 25

desalination

Front 26

freshwater that lies beneath the earths surface.

Back 26

groundwater

Front 27

underground porous rock layer often saturated by very slow flows of water is called this.

Back 27

aquifer
