Science 8th Grade 8.10A

Which one heats and cools fastest?

• land
• sea
• both are the same rate
• air

____________ occurs when heat is transferred into an object through motion or movement; an example would be boiling water.

• conduction
• convection
• radiation

If you are sitting on the beach during the day enjoying a cool breeze, which way will it be blowing?

• from sea to land
• from land to sea
• from north to south
• from east to west

The cycle that powers the ocean currents, weather, and tectonic plates it called

• conduction current
• radiation
• condition current
• convection current

The transmission of energy by two objects touching is called

• conduction
• convection
• contraction
• radiation

The main reason that we have currents in the ocean and air is

• the sun heats the air and ocean evenly everywhere
• the heat inside the earth heats the ocean and the ocean heats the air
• the sun cannot heat both the air and water, so one must heat the other
• the sun heats air and water more at the equator because it receives more direct sunlight

Warm air _________ and cool air ___________.

• rises/sinks
• sinks/rises

Land heats up and cools down faster than water.

• True
• False

What is one role of the ocean in convection?

• to provide a home for animals
• to absorb & release heat
• To surf on
• To drink from

Energy for convection on the Earth comes from...

• The sun
• The moon
• Solar winds
• The ocean
