Using Earth Science Knowladge

Front 1

Tapographic map

Back 1

a topographic map is a tool that shows elevation of land by using a series of connected lines.

Front 2

relief map

Back 2

a relief map is a tool that shows the elevation of land by using raised, or bumpy surfaces to represent the shape and elevation of the land.

Front 3

plains

Back 3

plains are low lying, flat areas of land. they are often grassy with few or no trees.

Front 4

deserts

Back 4

deserts are areas that receive little precipition (water) and have few plants.

Front 5

plateaus

Back 5

are flat areas of land, but they are found at high elevations. they usually have steep sides.

Front 6

basin

Back 6

A basin is a low-lying area that collects water from various streams, rivers, and lakes. the great lakes basin is one example.

Front 7

rivers

Back 7

are large, natural streams of flowing water. they end up in other rivers,lakes, or oceans.

Front 8

continental divide

Back 8

is the elevated point at which the flowing water on a continent goes in one direction or another.

Front 9

mountains

Back 9

are areas of land rising 2000ft. or more above the area around it. mountains can be on land or uner the ocean.

Front 10

mountain chains

Back 10

are groups of mountain ranges that can cover thousands of miles.

Front 11

mountain ranges

Back 11

are groups of similar mountains found together.

Front 12

rock cycle

Back 12

rocks can change into new rocks over and over again through the process called the rock cycle.

Front 13

core

Back 13

the core of the earth is very hot and dense.

Front 14

crust

Back 14

the crust of the earth is the outer layer we live on and the land found under the ocean.

Front 15

metamorphic rocks

Back 15

are formed when rock is placed under a lot of heat and pressure. this forms completely new types of rock.

Front 16

igneaus rocks

Back 16

are formed from the melting and cooling of rock. the rock is melted under the crust of the earth, then it cools.

Front 17

sedimentary rocks

Back 17

are usually formed frim the layering compacting and cementing of particles.

Front 18

minerals

Back 18

are none-living naturally occurring compounds in the earth.

Front 19

weathering

Back 19

is the process in which all kinds of rocks are broken down into smaller pieces over time.

Front 20

mechanical weathering

Back 20

occurs when plants are chemicals change the rocks into new substances, causing the rock th break down into smaller pieces.
