100
Nature’s way of recycling water.
What is the water cycle?
100
Gray clouds that cover the lower part of the sky; rain or snow falls from them
What are stratus clouds?
100
Conditions of the air over a short period time, such as hours, days and weeks.
What is weather?
100
Movement of air due to changes in air pressure.
What is wind?
100
The layer of the atmosphere closest to the surface where life exists and weather takes place.
What is the troposphere?
200
The process of water changing into an invisible gas called water vapor
What is evaporation?
200
White, puffy clouds that look like piles of cotton; they are known as fair-weather clouds
What are cumulus clouds?
200
Scientists who study weather
Who are meteorologists?
200
Warm air over land rises, while cool air over the ocean sinks, resulting in a cool breeze that blows toward the land.
What is a sea breeze?
200
Layer of the atmosphere that contains the ozone layer, which helps absorb harmful ultraviolet rays from the sun.
What is the stratosphere?
300
Amount of water vapor in the air
What is humidity?
300
Thin, feathery clouds that appear high in the atmosphere; they are made of ice crystals.
What are cirrus clouds?
300
An established pattern of weather tracked over a long period of time in a certain geographical area.
What is climate?
300
Describes winds that form due to differences in air pressure over a small area.
What is local winds?
300
The way in which heat is transferred through the atmosphere.
What is convection?
400
The process of water vapor turning into water droplets.
What is condensation?
400
Type of stratus cloud that forms at the earth’s surface.
What is fog?
400
The type of weather associated with low pressure air.
What is rainy/cloudy?
400
Warm, steady winds that blow towards the equator from the eastern direction.
What are trade winds?
400
The two most abundant gases in the atmosphere.
What is nitrogen and oxygen?
500
Water that returns to earth as rain, snow, sleet or hail.
What is precipitation?
500
Tall, dark clouds that mean thunderstorms with heavy rain and strong winds
What are cumulonimbus clouds?
500
The type of weather associated with high pressure air.
What is sunny/dry?
500
Trade winds, polar easterlies, prevailing westerlies are all examples
What are global winds?
500
This decreases with altitude in the troposphere.
What is air pressure?
