false - many need fresh water

Back 5

True or False -

plants and animals can only use salt water

Front 6

3%

Back 6

Fresh water makes up [97% or 3%] of the earth's water

Front 7

False - less than 1% is easily accessible

Back 7

True or False -

There is lots of freshwater easily accessible on the earth's surface

Front 8

rivers

Back 8

Rain and snow supply water to the surface reservoirs - lakes and ___

Front 9

80%

Back 9

Ice, Lakes and Rivers hold about ___ % of the earth's freshwater

Front 10

groundwater

Back 10

The remaining 20% of the earth's freshwater is found in ___

Front 11

wells

Back 11

many people get their water by drilling ___ into the layers of groundwater

Front 12

cryosphere

Back 12

About 79% of the earth's freshwater is found in the ___

Front 13

TRUE

Back 13

True or False -
Water can be stored as ice for thousands of years before melting and becoming liquid in other reservoirs.

Front 14

mineral

Back 14

A diamond is an example of a [element or a mineral]?

Front 15

False - you need to have all 5

Back 15

True or False -
To be a mineral - you must only have 3 of the 5 qualities - naturally occurring, inorganic, solid, crystal structure and definite composition

Front 16

physical

Back 16

minerals are identified by their ______ properties: color, streak, hardness, luster and crystal shape

Front 17

streak

Back 17

the color of a mineral's powder is called its ___

Front 18

hardness

Back 18

how easily a mineral can be scratched is its ___

Front 19

Luster

Back 19

how a mineral reflects light is its ---

Front 20

formed

Back 20

scientists classify rocks according to how they are ___

Front 21

Igneous rocks

Back 21

These rocks are formed from molten material [magma] cooling then hardening

Front 22

lava

Back 22

Magma is found deep inside the earth but sometimes erupts from volcanoes as ___

Front 23

sedimentary

Back 23

these rocks form when forces such as water, wind and ice break down rocks into small pieces called sediment

Front 24

metamorphic

Back 24

rocks that form when extreme temperatures and pressure within the earth change; these rocks do not melt - instead their compositions or their structures change.

Front 25

hard boiled egg

Back 25

The earth's internal structure is often compared to a ____

Front 26

crust

Back 26

this is the brittle outer layer of the geosphere - like the shell of a hard boiled egg

Front 27

under

Back 27

the crust is found [under or above] the soil on continents and the ocean

Front 28

This is because of their composition - continental crust is made of igneous, sedimentary and metamorphic crocks - oceanic is made of only igneous rock

Back 28

Explain why the oceanic crust is thinner and denser than the continental crust

Front 29

mantle

Back 29

the middle and largest layer of the geosphere is the ___

Front 30

hotter

Back 30

the mantle is made of rock - the mantle rocks are --- and denser than those in the crust

Front 31

high

Back 31

parts of the mantle have temperatures that are so [high/low] that the rocks flow like partially melted plastic

Front 32

core

Back 32

the center of the earth is the ___

Front 33

yolk

Back 33

Using the hard boiled egg example - the core would be equal to the ___

Front 34

rock

Back 34

unlike the crust and mantle, the core is not made of __

Front 35

metal iron

Back 35

the core is mostly made of ___ and small amounts of nickel

Front 36

inner and outer core

Back 36

the core of the earth is divided into 2 parts called --- and ---

Front 37

inner

Back 37

this core is a dense ball of solid iron

Front 38

outer

Back 38

this core is a liquid

Front 39

TRUE

Back 39

True/False -
all openings below the water table are full of groundwater

Front 40

mineral

Back 40

To be a ----- you must only have 5 qualities - naturally occurring, inorganic, solid, crystal structure and definite composition

Front 41

state

Back 41

water is found as a solid, liquid, or gas - this is because water changes its ____

Front 42

ground water

Back 42

water that is stored in cracks and pores beneath the earth's surface

Front 43

True

Back 43

True or False - most of the earth's fresh water is frozen

Front 44

Back 44

the frozen portion of water on the earth's surface

Front 45

Back 45

the cryosphere consists of snow, glaciers and ___
