Convection Current Assessment (7th grade)

What is the driving force of currents in the ocean and atmosphere?

• equal heating of Earth by the Sun

• Solar radiation heating only the oceans

• Solar radiation heating only the land surfaces

• Unequal heating of Earth by the sun

In the Earth's mantle, convection currents are caused by the move of

• tectonic plates

• wind

• fluids

• gravity

Less dense hot magma moves......

• across

• upward

• downward

• stays still
