Weather and Climate

What is the main source of heat energy for weather on the earth?

• Air

• metals

• the sun

• precipitation

Under what conditions will the vortex of a tornado form?

• When deep ocean currents result from changes in temperature

• When greenhouse gases trap the earth’s heat

• When water spirals in a whirlpool

• When air masses of very different temperature and humidity conditions meet

What is radiation?

• The transfer of energy when two object are in contact

• Heat that we feel that is transferred in waves.

How does convection move material?

• Heat transfers through open space

• Rays from the sun push an object

• Less dense areas rise, and more dense areas sink

• A material changes from a liquid to a gas

What is conduction?

• When heat moves through a vacuum

• When heat transfers between two objects that are touching

• When heat flows from a cool to a hot object

• When heat causes a material to move around
