Weather
| Question | Answer |
|---|---|
| In which layer of the atmosphere does weather occur? | Troposphere |
| What are the names of the layers of the atmosphere, in order, starting at the surface of the earth? | troposphere, stratosphere, mesosphere, thermosphere, exosphere |
| In which layer of the atmosphere do you find the ozone layer? | stratosphere |
| How does the ozone layer protect people? | It blocks solar radiation |
| Which layer of the atmosphere is surprisingly very warm? | thermosphere |
| Which is more dense, warm air or cold air? | cold air |
| Which can hold more moisture, warm air or cold air? | warm air |
| Air masses with higher humidity are known as _______________ air masses. | maritime |
| Air masses with lower humidity are known as _______________ air masses. | continental |
| Air masses with high humidity form over _________________. | bodies of water |
| Air masses with low humidity form over _________________. | land |
| Cold air masses are referred to as __________________. | Polar |
| Warm to hot air masses are referred to as __________________. | tropical |
| MOST solar radiation that strikes the earth goes where? | It is absorbed by the surface. |
| When does dew form? | When the air temperature reaches the dew point |
| Which air mass (warm or cold) will rise over the other? | warm air rises, cold air sinks |
| What are the three forms of energy transfer? | Radiation, conduction, and convection |
| Why do high pressure air masses have fair weather? | The pressure keeps air from rising and because of that clouds cannot form. |
| Why do low pressure air masses tend to have stormy weather? | Warmer air is able to rise, forming clouds. Sometimes those clouds cause precipitation. |
| What is precipitation? | Water in any form falling from the sky. |
| Term for when land masses force air upward where the water vapor condenses into clouds. | orographic lifting |
| Why does warm air rise? | Warm air is less dense than cold air |
| Why is warm air less dense than cold air | warm air molecules are moving more and take up more space |
| Is humid air more or less dense than drier air? | less dense |
| What two factors affect the amount of solar radiation that is absorbed or reflected? | what the surface is made of and amount of solar radiation |
| What two factors affect the amount of solar radiation an area receives | latitude (angle of the sun) and season |
| Which surface warms faster: land or water | land |
| Which surface holds on to its heat longer at the end of the day: land or water | water |
| When does dew form? | When relative humidity reaches 100% and the air temperature and dew temperature are the same. |
| What causes wind? | heating of the earth's surface and rotation of the earth on its axis |
| What forms can "dew" take? | frost, fog, dew, and clouds |
| What is special about the troposphere? | weather occurs here |
| What is special about the stratosphere? | ozone layer is found there |
| What is special about the mesosphere? | Air is thick enough here to burn debris/meteors |
| What is special about the thermosphere? | Northern (and Southern) Lights are produced in the ionosphere here |
| Moisture, lifting/rising air, and unstable air produce... | storms |
| The surface of the earth is warmed by what process? | radiation |
| The warmed surface of the earth transfers heat to the air above it by what process? | conduction |
| As air warms it becomes less ______________. | dense |
| Warming air rising and being replaced by cooler air is the process of _______________. | convection |
| Warming air rising and being replaced by cooler air produces ________________. | wind |
| water vapor condensing into clouds ____________ energy. | releases |
| _______________ is the kinetic energy of moving atoms in a substance. | temperature |
