Science Ch. 5

Front 1

radiation

Back 1

The heat transfer of energy through empty space. there is no didrect contact between heat sourse and an object (sunlight)

Front 2

heat transfer

Back 2

Movement from a hot object to a cool object

Front 3

Basalt

Back 3

a rock that makes up much of the ocean floor. A dark dense igneous rock with a fine texture found in the oceanic crust

Front 4

Asthenosphere

Back 4

A soft layer of the mantle on which the lithospere floats

Front 5

Crust

Back 5

A layer of rock that forms earth outer surface. It is much thinner than the layer that lies beneath it. (like an onion skin)

Front 6

Outer core

Back 6

The layer made up of liquid iron and nickel (molten metal) and surrounds the inner core

Front 7

Lithosphere

Back 7

A rigid layer made up of the uppermost part of the mantle and the crust

Front 8

Pressure

Back 8

The force pushing on a surface or area

Front 9

Seismic Waves

Back 9

A wave produced by and earthquake. Vibrations that travel through Earth carrying the energy released during an earthquake.

Front 10

Where does Convection currents occur

Back 10

heat in the mantle and outer core

Front 11

What is Climate??? <3

Back 11

Climate refers to the average weather conditions in a certain place over many years.

Front 12

What do greenhouse gases do?

Back 12

Gases in the atmosphere that trap energy

Front 13

Greenhouse Effect

Back 13

Process by which Earth's atmosphere traps solar energy

Front 14

Global Warming

Back 14

Gradual increase in the temperature of Earth's atmosphere

Front 15

Mantle

Back 15

The layer of hot solid material between Earth's crust and core

Front 16

Outer core

Back 16

A layer of molten iron and nickel that surrounds the inner core of the earth

Front 17

Inner core

Back 17

A dense sphere of solid iron and nickel at the center of the earth

Front 18

Granite

Back 18

A usuallylight colored igneous rock that is found in the continental crust

Front 19

Greenhouse Gases

Back 19

Gases in the atmosphere that trap solar energy

Front 20

Name 3 greenhouse gases

Back 20

carbon dioxide, wate vapor, methan

Front 21

What is the outcome of burning wood, coal , oil and natural gas

Back 21

Carbon dioxide is added to the air

Front 22

How are humans contirbuting to global warming

Back 22

by the burning of wood, coal, oil and natural gas

Front 23

true or false. The amount of carbon dioxide in the air has been steadily increasing

Back 23

True

Front 24

T/F: Everyone agrees about the causes of global warming

Back 24

False

Front 25

How might changes in solar energy affect earth's climate?

Back 25

The water will melt and the wate levels will rise and it will eventually submerge more land

Front 26

indirect evidence

Back 26

evidence you infer (such as rom seismic waves)

Front 27

Temperature (to the center of the earth)

Back 27

just beneath the surface the surrounding rock is cool. As you go further down it gets warmer,

Front 28

Why is it difficult to determine the earth's inner structure?

Back 28

because of the exteme conditions in the earth's interior.

Front 29

how are siesmic waves used to prvide evidence about earths' interior?

Back 29

they use data and found interior is made up of several layers

Front 30

liquid - which layer
solid
solid but able to flow

Back 30

liquid :outer core
soid: lower mantle, inner core, lithosphere
solid but able to flow: asthensphere

Front 31

continental drift

Back 31

the hypothese that the continents slowly move across the earth's surface

Front 32

pangaea

Back 32

the name of the single landmark that broke apart 200 million years agao and ge rise to today's continents

Front 33

fossil

Back 33

a trace of an anceint organism that has been preserved in rock.

Front 34

conduction

Back 34

Heat transfer within a material or between maters that are TOUCHING. (a spoon in a pot of soup heats up by conduction)

Front 35

convection

Back 35

heat transfer by the movement of curents within a fluid. The heated particles of fludid begin to flow. this flow transfers heat from one part of the fluid to another

Front 36

density

Back 36

a measure of how much mass there is in a volume of a substance.

Front 37

convection current

Back 37

the flow that transfers heat within a fluid. the heating & cooling of the fluids set the currents in motion.
