|
|
|
The portion of the atmosphere that absorbs high-energy radiation is the
hydrosphere. troposphere. mesosphere. thermosphere. |
thermosphere.
|
|
|
Chlorofluorocarbons
are toxic to humans. combine with dust particles to form aerosols that cool the Earth. react to destroy ozone. react to produce ozone. |
react to destroy ozone.
|
|
|
The layer of air closest to the Earth is the
tropopause. troposphere. mesosphere. stratosphere. |
troposphere.
|
|
|

light. sound. radio waves. X-rays. |
sound
|
|
|
The region of the globe directly beneath the Sun is warmer because
it receives the least concentrated radiation. it receives the most concentrated radiation. it receives light of a different frequency. it receives light of a different wavelength. |
it receives the most concentrated radiation.
|
|
|
Atmospheric convection and advection
are more effective than conduction in transferring heat around the globe. are less effective than conduction in transferring heat around the globe. are about equally effective as conduction in transferring heat around the globe. are unimportant processes in transferring heat around the globe. |
are more effective than conduction in transferring heat around the globe.
|
|
|
______________ plays an important role in heat transfer and storage because it commonly occurs naturally on Earth in all three states, solid, liquid, and gas.
Hydrogen Air Soil Water |
water
|
|
|
The Earth remains warm at night because
the albedo absorbs and retains much of the radiation emitted by the Earth's surface. the atmosphere absorbs and retains much of the radiation emitted by the Moon. the atmosphere absorbs and retains much of the radiation emitted from the Earth's surface. dark sky retains more heat than blue sky. |
the atmosphere absorbs and retains much of the radiation emitted from the Earth's surface.
|
|
|
Evaporation from a body of water
cools the water and air around it because of specific heat transfer. cools the water and the air around it because of latent heat transfer. warms the water and the air around it. has no effect on the temperature of the water and air around it. |
cools the water and air around it because of specific heat transfer.
|
|
|
Locations at the same latitude, which receive the same amount of solar radiation,
will have the same climate. can have different climates. are not affected by their heat storage properties. occur during the summer months only. |
can have different climates.
|
|
|
The sky appears blue because
the blue component of sunlight scatters more than the other frequencies and colors the atmosphere. light is reflected by the Earth's oceans. there is no atmosphere to scatter the light in the uppermost atmosphere. only blue frequencies are transmitted by the Sun. |
the blue component of sunlight scatters more than the other frequencies and colors the atmosphere.
|
|
|
When an object absorbs radiation,
the photons disappear and are converted to another form of energy. the energy is lost. the photons reflect out to space. the photons slow down. |
the photons disappear and are converted to another form of energy.
|
|
|
Which of the following statements about atmospheric humidity is correct?
Dew forms when warm moist air comes in contact with cool surfaces. Rain or fog is likely to occur when cool moist air is heated. Cold air can hold more moisture than warm air. Fog occurs when warm moist air from the ocean blows over warmer land surfaces. |
Dew forms when warm moist air comes in contact with cool surfaces.
|
|
|
________________ _______________ is the mass of water vapor in a given amount of air expressed in grams per cubic meter (g/m3).
Relative humidity Absolute humidity Dew point Partial humidity |
Absolute humidity
|
|
|
El Niño is a weather pattern caused by
the shifting motion of ocean currents. the shifting motion of air currents. orographic lifting. frontal wedging. |
the shifting motion of ocean currents.
|
|
|
When a warm air mass overtakes a cool one
the cool air rises, leading to precipitation. the cool air rises, leading to fair weather. the warm air rises, cools adiabatically which leads to precipitation. the warm air rises, leading to fair weather. |
the warm air rises, cools adiabatically which leads to precipitation.
|
|
|
Monsoons
blow from land to sea in early summer bringing drought. blow from sea to land when the Earth cools, bringing rain. blow from land to sea in summer bringing rain. blow from sea to land in summer bringing rain. |
blow from sea to land in summer bringing rain.
|
|
|
If one portion of the atmosphere becomes warmer than surrounding air,
the warm air contracts and falls. a high pressure forms. clouds disappear. the warm air expands and rises. |
the warm air expands and rises.
|
|
|
If a large pressure difference occurs over a short distance
there is little wind. it rains. it snows. there is a lot of wind. |
there is a lot of wind.
|
|
|
