10

what fuels currents

heat from the sun

11

Energy traveling through space

Radiation

12

How does heat get from the sun to the earth

radiation

13

Heat transferred from one object to another or one molecule to another

conduction

14

Heat is absorbed by the land by

conduction

15

heat is distributed over eath by

convection

16

The transfer of heat through fluids

convection

17

At the equator, the sun’s radiation hits nearly directly at almost

90 degrees

18

concentrated at smaller surface area

solar radiation

19

since Solar radiation is concentrated at smaller surface area, this means there will be

warmer temperatures

20

At poles, the sun’s radiation hits at more of an

angle

21

Spreads the radiation over a larger area =

cooler tempertures

22

Warm air is ____ dense than cold air.

less

23

Something with higher density _____.

sinks

24

Earth is neither _____ nor _______

still/smooth

25

sinks and flows away from the poles.

cold air

26

cold air Collides with air from equator around _____ latitude and gets pushed up

60 degrees

27

Air can either move back to _____ (to repeat process) or towards the ______

poles/equator
