The Science of Fire - Conection

What is convection?

• Heat transfer through direct contact between solids.

• Heat transfer through electromagnetic waves.

• Heat transfer due to the bulk movement of fluids.

• Heat transfer that occurs only in a vacuum.

What is the primary driving force behind the movement of fluids in convection?

• Magnetic forces within the fluid.

• Differences in density caused by temperature changes.

• Chemical reactions occurring in the fluid.

• Electrical currents flowing through the fluid.

What are the large convection cells in Earth's atmosphere, responsible for global air circulation, called?

• Ferrel Cells

• Polar Cells

• Hadley Cells

• Coriolis Cells

What major geological process is believed to be driven by the convection of magma within Earth's mantle?

• Erosion of landforms.

• Weathering of rocks.

• Plate tectonics.

• Sedimentation in oceans.
