Environment/ Weather
| Question | Answer |
|---|---|
| water vapor or moisture in the air | humidity |
| layer of atmosphere immediately surrounding the earth where the weather occurs | troposphere |
| energy from the sun causes liquid water to change to a gas | evaporation |
| the force that pulls precipitation back to Earth | gravity |
| a very large body of air that forms over areas where the temperature doesn't change | air mass |
| changing from a gas to a liquid (water drops that form clouds) | condensation |
| "battle line" between 2 air masses | front |
| when a front passes through a region, the weather does this | changes quickly |
| tool to measure wind direction | wind vane |
| tool to measure wind speed | anemometer |
| tool to measure air temperature | thermometer |
| tool to measure air pressure | barometer |
| the condition of the air (wind speed and direction, temperature, air pressure, humidity) that surrounds our Earth | weather |
| when the northern hemisphere tilts towards the sun we have what season | summer |
| when the northern hemisphere tilts away from the sun we have what season | winter |
| air is heated directly by... | the land and water |
| cold fronts bring... | stormy weather and a drop in temperature |
| warm fronts bring... | maybe a light rain and an increase in temperature |
| a low pressure system means... | rainy weather |
| a high pressure system means... | sunny skies |
| all the layers of air that surround the Earth | atmosphere |
| moisture that returns to the Earth as rain, sleet, hail, or snow | precipitation |
| a scientist who studies the weather | meteorologist |
| water in its gaseous state | water vapor |
| the reason for the seasons | Earth's tilt and revolution |
| the reason for day and night | Earth's rotation (spinning on its axis) |
| horizontal movement of air | wind |
| thin layer of water that covers the Earth's surface | hydrosphere |
| thin layer of rock that covers the Earth's surface | lithosphere |
| changing from a liquid to a gas | evaporation |
| three parts of the water cycle (it repeats) | evaporation, condensation, precipitation (that runs off into lakes or rivers) |
| the lowest form of a cloud (it meets the ground) | fog |
| this type of cloud is like a grey blanket that covers the sky | stratus |
| this fluffy white cloud means fair weather | cumulus |
| aka "thunderhead" cloud | cumulonimbus |
| this storm brings high winds and rain, forms over an ocean, and causes great distruction to coastal areas | hurricane |
| this natural disaster is like a funnel of high winds and debris that forms over flat land and is hard to predict | tornado |
