The steam that can be seen coming out of a boiling kettle consists of condensing water droplets. These water droplets move upward with the hot water vapor coming out of the kettle. The process of hotter air rising and cooler air falling is called convection. What role does convection play in the atmosphere?
A. Convection makes the air warmer at higher altitudes.
B. Convection currents distribute heat in the atmosphere.
C. Convection prevents the air in the atmosphere from moving.
D. Convection transfers heat from the atmosphere to the ocean.

How did the miller-urey experiment impact the way scientists think about the origins of life? use what you know about the miller-urey experiments to discuss the factors needed for life to arise, and speculate on whether life could arise on another planet.

Darrel conducted an experiment with the following procedure: fill two cups with ice water. place an uninflated balloon snuggly onto your left index finger. blow a little air into an identical balloon, and place it onto your right index finger. place both fingers into the cups of ice water. darrel noticed that his right finger felt warmer in the ice water than did his left finger. which of the following does the experiment show? a. air is a good radiator of heat. b. air is a good insulator of heat. c. air is a good conductor of heat. d. air is a good convector of heat.
