Question 1

what does the transformation of solar energy do?

Answer 1

the transformation of solar energy drives the movement of water in the atmosphere and hydrosphere, as well as through and overland

Question 2

nuclear energy

Answer 2

is transformed into thermal energy by radioactive decay in Earths crust and mantle
this thermal energy causes volcanic activity by making the tectonic plate movements which result in hot springs

Question 3

gravitational energy

Answer 3

this transformation helps move water

Question 4

what does most of Earth’s solar energy consist of?

Answer 4

visible light, infrared radiation, and ultraviolet radiation

Question 5

what happens to solar energy when it is passed through the Earth?

Answer 5

it transforms into thermal energy

Question 6

conduction

Answer 6

heats the air through collisions between molecules in the air and the surface

Question 7

convection

Answer 7

moves warm air from close to the surface upward then downward

Question 8

infrared radiation does what to the air

Answer 8

heats it

Question 9

why are terrestrial ecosystems more likely to getting radiation exposure than aquatic ones

Answer 9

radioactive materials accumulate in soil while in aquatic ones they pass more quickly

Question 10

what is specific heat capacity?

Question 11

what three things work today to transfer heat into our atmosphere?

Answer 11

radiation, conduction, convection
