Earth's Atmosphere and Environmental Issues Flashcard

Front

What causes the temperature to increase in the stratosphere as altitude increases?

Back

The absorption of ultraviolet radiation by ozone.

Front

As the ozone layer recovers, which environmental change is most likely to occur?

Back

Decreased levels of harmful ultraviolet radiation reaching Earth's surface

Front

How do radiation, convection, and conduction contribute to the formation of a sea breeze during the daytime?

Back

Radiation heats the land more quickly than the sea, conduction transfers heat from the land to the air, and convection causes the warm air to rise, allowing cooler air from the sea to flow in.

Front

What mechanism is responsible for the movement of heat through the surrounding cold water in the deep ocean where sunlight does not penetrate?

Back

Convection

Front

A hot metal rod is placed in contact with a cooler metal surface. What will occur?

Back

Heat energy will transfer from the rod to the surface, causing the rod's temperature to decrease.

Front

Which mechanism can influence the temperature of the ocean or atmosphere, but not the solid ground?

Back

convection

Front

How does the uneven heating of Earth's surface influence atmospheric conditions?

Back

It causes variations in air pressure across different regions.

Front

When air is heated, it expands and becomes less dense. If two regions on Earth have similar atmospheric conditions, what occurs when one region is exposed to more intense sunlight than the other?

Back

The air in the region with more sunlight will rise above the air in the other region.

Front

Which layer of Earth's atmosphere is closest to the surface and receives the least direct radiation from the sun? Options: the exosphere, the ionosphere, the stratosphere, the troposphere

Back

the troposphere

Front

How does temperature change in the mesosphere?

Back

Temperature decreases as altitude increases.
