|
Term
| What two gases make up 99 percent of dry air? |
|
Definition
|
|
Term
| What gas plays a significant role in heating the atmosphere? |
|
Definition
|
|
Term

|
Definition
| Water vapor is the source of all clouds and precipitation |
|
|
Term
| What are some particles that remain suspended for long periods of time? |
|
Definition
| Sea salts from breaking waves, fine soil blown into air, smoke and soot from fires, pollen and microorganisms lifted by the wind, and ash and dust from volcanic eruptions |
|
|
Term
| When do oxygen atoms split into single atoms of oxygen? |
|
Definition
| When they absorb ultraviolet radiation emitted from the sun |
|
|
Term
|
Definition
| Harmful UV radiation from the sun |
|
|
Term
| What accounts for nearly half the primary pollutants by weight? |
|
Definition
| Emissions from transportation vehicles |
|
|
Term
| What secondary pollutants? |
|
Definition
| They are not emitted directly into air, they form in the atmosphere when reactions take place among primary pollutants and other substance |
|
|
Term
| What are photochemical reactions? |
|
Definition
| Reaction triggered by strong sunlight |
|
|
Term
| What is atmospheric pressure? is simply the weight of the air above. |
|
Definition
| Atmospheric pressure is simply the weight of the air above |
|
|
Term
| How many layers is the atmosphere divided into? |
|
Definition
|
|
Term
| In what layer do most weather phenomena occur? |
|
Definition
|
|
Term
| Where does most energy that drives weather and climate come from? |
|
Definition
|
|
Term
| What creates winds and dives the ocean's currents? |
|
Definition
| It's the unequal heating of Earth that creates winds and drives the ocean currents. These movements transport heat from the tropics toward the poles in an attempt to balance energy differences. The results of these processes are the phenomena we call weather |
|
|
Term
|
Definition
| The spinning of Earth about its axis |
|
|
Term
|
Definition
| The movement of Earth in its orbit around the sun |
|
|
Term
| What are the degrees the Earth is tilted? |
|
Definition
|
|
Term
| What is length of daylight determined by? |
|
Definition
| It is determined by Earth's position in orbit |
|
|
Term
| What are the three mechanisms for energy transfer? |
|
Definition
| Conduction, convection and radiation |
|
|
Term
| What can radiant energy travel through? |
|
Definition
| Radiant energy travel through the vacuum of space |
|
|
Term
| Do hot or cold objects radiate more energy? |
|
Definition
| Hotter objects radiate more total energy per unit area than colder objects do |
|
|
Term
|
Definition
| It occurs when light bounces off an object |
|
|
Term
| Does land or water heat to higher temperature faster? |
|
Definition
| Land heats more rapidly and to higher temperature than water. |
|
|
Term
| What is a coast called in which blow from the ocean onto the shore? |
|
Definition
|
|
Term
|
Definition
| Is the fraction of the total radiation that is reflected by any surface |
|
|
Term
| What does the extent of cloud cover influence? |
|
Definition
| By reducing the amount of incoming solar radiation, the maximum temperatures on a cloud-covered day will be lower than on a day when the clouds are absent and the sky is clear |
|
|
Term
| What type of lines connects points of the same temperature? |
