Why does ice float?

• Due to convection currents

• It is more dense than water.

• It is less dense than water.

What causes convection current in the Earth?

• The uneven heating on each layer inside the Earth.

• The crusts outer layer.

• The temperatures we feel outside.

Can convection currents occur in a solid?

• No.

  just in a liquid and gas.

• Yes.

  In a solid, liquid, and gas.

What is an example of a convection current?

• Touching a hot spoon that was in a soup bowl.

• Feeling the suns rays on a nice summer day.

• Touching an iron skillet after cooking and feeling the heat.

  Currents only move in a liquid and gas.

• Yes.

  Convection currents move through a solid.

Heat transfer by convection is caused by differences in what two things:

• Thickness and material

• Weight and electricity

• Temperature and density

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

• conduction current
• radiation
• condition current
• convection current
