Weather

What is weather?

• the condition of Earth’s atmosphere at a certain time and place

• the condition of USA's atmosphere at a certain time and place

• the condition of Earth’s atmosphere at a any time and place

• the condition of Earth’s Sun at a certain time and place

Factors that describe weather

• rain, snow, hail, sleet

• barometer, anemometer, speedometer; psychrometer

• temperature, humidity, precipitation, air pressure, wind, and visibility

• ocean currents

Amount of water vapor is

• humidity

• dew point

• relative humidity

• barometer

The humidity of air increases as ...

• the amount of water vapor is zero

• the amount of water vapor stays the same

• the amount of water vapor decreases

• the amount of water vapor increases

The amount of water vapor in the air compared to the amount of water vapor needed to reach saturation is

• humidity

• relative humidity

• dew point

• barometer

When air is saturated, the rates of evaporation and condensation are ...

• zero

• decreasing

• equal

• increasing

It measures relative humidity

• speedometer

• rain gauge

• psychrometers

• barometer

The temperature at which more condensation than evaporation occurs

• humidity

• relative humidity

• dew point

• wind

any form of water that falls to Earth’s surface from the clouds and the four main forms are rain, snow, hail, and sleet

• precipitation

• condensation

• evaporation

• transportation

How does snow form?

•  when water vapor turns directly into condensation

•  when water vapor turns directly into a liquid

•  when water vapor turns directly into a solid

•  when water vapor turns directly into a gas
