Convection Currents

Which one heats and cools fastest?

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

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

• conduction current
• radiation
• condition current
• convection current

The energy from the sun is transmitted through movement of electromagnetic waves by

• conduction
• convection
• contraction
• radiation

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

Energy for convection on the Earth comes from...

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

In convection, COOL air

• Rises
• Sinks

In convection, WARM air

• Rises
• Sinks

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

The way the heat is moving from the hot coffee is called...

• convection
• radiation
• insulation
• conduction
