1. A student models convection current in a laboratory activity. om
The warm air in Earth's atmosphere and the warm water in Earth's
oceans sink instead of rise.

D
The heat source for Earth's atmosphere and oceans is the sun, which
heats from above instead of below.
Heat source
Convection cells in Earth's atmosphere and oceans Flow in the same
direction instead of opposite directions.
e
Cold air in Earth's atmosphere and cold water in Earth's oceans are less
dense than warm air and warm
water instead of being more dense.
e
How are the convection currents in the student's model different from the convection
currents in Earth's atmosphere and oceans?
