When a layer of cool air at the surface of Earth is found under a layer of warmer air above it, the result is known as
the Coriolis effect
temperature inversion.
the greenhouse effect.
an upwelling.
Which of these effects generally occurs as the result of a warm air mass and a cooler air mass converging at Earth’s surface?
The sky becomes clear.
Winds die down.
Cloud formation decreases.

Scientists have found fossils of tropical plants in Antarctica. How could tropical plants have grown in Antarctica?
At one time, Earth’s entire surface was a tropical rain forest.
At one time, Antarctica was located closer to the equator.
The rotation of Earth has increased, causing cooling of the atmosphere.

temperature gradient.
The primitive atmosphere of Earth was deficient in free oxygen. What process was primarily responsible for the development of the present percentage of free oxygen in the Earth’s atmosphere?
outgassing
volcanic eruptions
photosynthesis
oxidation of iron-based minerals
