2.1 Local energy budgets

Question 1

Albedo

Answer 1

Reflectivity of the Earth’s surfaces

Question 2

Atmosphere

Answer 2

Mixture of gases, mainly hydrogen, oxygen, argon, carbon dioxide, and water vapour. That surround the earth.

Question 3

Climate

Answer 3

Average weather conditions of an are over a period of years.

Question 4

Conduction

Answer 4

Transfer of heat by contact

Question 5

Convection

Answer 5

Transfer of heat by the movement of a gas or liquid.

Question 6

Latent hear transfer

Answer 6

Transfer of energy via evaporation and condensation.

Water turned into vapour, heat used up. Water becomes liquid, heat is released.

Question 7

Sensible heat transfer

Answer 7

Transfer of energy by convection and conduction

Question 8

Inversion

Answer 8

Situation in which cold air is found closer to the ground and warmer air is found above it. Common in valleys and basins.

Question 9

Radiation

Answer 9

Emission of electromagnetic waves, like x-ray and short and long-waves.

Question 10

Long-wave radiation

Answer 10

Radiation from a relatively cold body, such as the earth.

Question 11

Short-wave radiation

Answer 11

AKA ultra violet radiation, it is radiation from a very hot body, such as the sun. It travels in short wave lengths.

Question 12

Weather

Answer 12

The state of the atmosphere at a given place or time.

Question 13

I insolation

Answer 13

Incoming solar radiation
