| weather | weather is the result of many factors. air temp, air pressure, humidity , cloud cover, wind speed and direction, precepetation and sunshine
🗑
|
||||
| jet stream | strong winds caused by differences in air temp and air pressure. They are found at the very top of the tropsphere
🗑
|
||||
| ozone layer | a gas that exists in the statosphere that protects us from the suns ultra violet rays
🗑
|
||||
| stratosphere | second layer of the atmospher. 19% of our gases is here. Jets fly here because there is less wind.
🗑
|
||||
| troposphere | 1st layer of the atmospher. All of our weather takes place here. 80% of our air is here.
🗑
|
||||
| atmosphere | a blanket of gases that surrounds the earth. our weather takes place in its lowest layer.
🗑
|
||||
| Thermometer | tool used to measure temperature
🗑
|
||||
| Meterologist | people who study the weather and try to froecast or predict the weather
🗑
|
||||
| Air Pressure | the amount that air pressure pushes on anything
🗑
|
||||
| High Pressure Area | a place where cool air sinks and pushes down on the earths surface with more pressuer
🗑
|
||||
| Colder | When there is high pressure it is ..
🗑
|
||||
| Low Air pressure | a place where warm air rises and pushes down on the earths surface with less air
🗑
|
||||
| warmer | when there is low pressure it is ...
🗑
|
||||
| Barometer | a tool that measures air pressure
🗑
|
||||
| Anemometer | a tool that measures wind speed
🗑
|
||||
| Clouds form | clouds form when water vapor rises up into the troposphere and cools. This causes it to condense back to water droplets which stay together as clouds.
🗑
|
||||
| Stratus Clouds | stratus clouds blanket the sky in layers, they are grayish looking and often bring precipitation. Blanket
🗑
|
||||
| what makes rain | stratus clouds
🗑
|
||||
| Cumulus Cloud | Cumulus are puffy, flat based clouds which often look like balls of cotton. They usually indicate fair weather.
🗑
|
||||
| Cirrus Clouds | Cirrus clouds are thin and feathery looking they flout very high in the sky and are made of tiny ice crystals.
🗑
|
||||
| Precipitation | moisture that falls from clouds to the ground in the form of rain, snow, sleet and hail
🗑
|
||||
| Wind Vane | a tool that shows wind direction
🗑
|
||||
| Rain gauge | a tool that measures precipitation
🗑
|
||||
| Humidity | the amound of water vapor in the air.
🗑
|
||||
| Hygrometer | a tool that measures humidity.
🗑
|
||||
| Water Cycle | the water cycle is an exchange of water between the earth and the atmosphere. There are three stages.
🗑
|
||||
| Evaporation | heat causes water (a liquid) to slowly evaporate or change from a liquid to a gas. this is called water vapor
🗑
|
||||
| Condensation | when water vapor cools it may condense or change back to liquid.
🗑
