What 2 main gasses make up air? Nitrogen and Oxygen Category 1 - 10

The instrument used to measure wind speed. Anemometer Category 1 - 20

The instrument used to measure air pressure. Barometer

The instrument used to measure humidity Psychrometer

Uneven heating on the earth’s surface Weather on earth is caused by…. Uneven heating on the earth’s surface

Name the layer of Earth’s atmosphere where weather happens. Troposphere

The ozone layer is found in which layer of Earth’s atmosphere Stratosphere

What happens to air pressure as you increase altitude? Decreases

Ultraviolet (UV) Radiation The ozone layer protects us from _________. Ultraviolet (UV) Radiation

The sun heats the earth by radiation The sun heats the earth by radiation. The earth heats the atmosphere by _____________. Heat from the Earth's core and radiation from the Sun is transferred to the surface of the Earth by conduction. Contact of the atmosphere with these warm surfaces transfers thermal energy, which then heats up the rest of the air through convection.

The source of energy that drives the water cycle is _____. The sun

Clouds are formed by the ___________ of water vapor in the atmosphere. Condensation

When water evaporates from plants. Transpiration

When water returns to earth in the form of rain, snow, sleet, or hail Precipitation

When liquid water absorbs energy and changes to water vapor (gas). Evaporation

This type of cloud is puffy with a flat bottom and usually means fair weather Cumulus

Temperature and Humidity (moisture) An air mass is a huge body of air with similar ______________ and ___________. Temperature and Humidity (moisture)

Maritime Tropical (mT); warm and moist Name and describe an air mass that forms over the Gulf of Mexico. Maritime Tropical (mT); warm and moist

Continental Polar (cP); cold and dry Name and describe an air mass that forms over northern Canada. Continental Polar (cP); cold and dry

The boundary between 2 air masses. Front

What kind of weather always occurs at fronts and why? Clouds and precipitation because the warmer, more humid air always rises.

What direction does wind spin in a low pressure storm such as a hurricane? Counter-clockwise

The word nimbus or nimbo associated with a cloud indicates what? Thunderstorms

Wind always blows from an area of _____pressure to an area of ______pressure. High;Low

All weather in the United States moves in what direction? Towards the Northeast
