DPM #2 Concepts

Front

What evidence do glacier scars in Africa provide?

Back

Africa was once in an area of the Earth that had a very cold climate.

Front

What process distributes heat around the globe helping to maintain fairly constant average temperatures?

Back

Convection.

Front

Why do hurricanes form in the tropical water around the equator?

Back

Because these waters are warm.

Front

What geological process is occurring at a subduction zone?

Back

Subduction.

Front

What cycle powers ocean currents, weather, and tectonic plates?

Back

Convection current.

Front

Define convection.

Back

The transfer of heat through the movement of fluids (liquids and gases).

Front

What is the difference between conduction and convection?

Back

Conduction is the transfer of heat through direct contact, while convection involves the movement of fluids.

Front

What is a divergent boundary?

Back

A tectonic plate boundary where two plates move away from each other.

Front

What is the role of ocean currents in climate?

Back

Ocean currents help regulate temperatures and weather patterns around the globe.

Front

What is the significance of warm ocean waters in hurricane formation?

Back

Warm waters provide the energy needed for hurricanes to develop and strengthen.
