The normal pattern of weather in an area over many years.
What is climate?
100
This is a mixture of gases that surrounds the planet.
What is atmosphere?
100
A body of air that has about the same temperature and moisture throughout.
What is air mass?
100
The overall condition of the atmosphere at a given time and place.
What is Weather?
100
These are used to measure temperature. They report degrees Fahrenheit and Celsius.
What is a Thermometer?
200
This flows fromt he water toward the land.
What is Sea Breeze?
200
This layer is the first part of the atmosphere struck by sunlight.
What is Thermosphere?
200
The boundary between two air masses with different properties. This is usually marked by a change in weather.
What is a front?
200
Scientists who study weather.
What is a Meteorologist?
200
These measure wind speed. Some also indicate the direction of the wind.
What is an Anemometer?
300
This flows from the land toward the water.
What is Land Breeze?
300
This layer is the coldest part of the Earth's atmosphere.
What is Mesosphere?
300
This forms when warm air moves into an area. Light rains are associated with this.
What is a Warm Front?
300
This type of system brings clear weather.
What is a high-pressure system?
300
These measure air pressure. In the US, air pressure is usually reported in inches of mercury.
What is a Barometer?
400
A name given to a periodic change in direction of warm ocean currents across the Pacific Ocean. It's events occur every five to seven years and can cause temporary changes in climate around the globe.
What is El Nino?
400
This layer is contains most of our planet's ozone (a form of oxygen.)
What is Stratosphere?
400
This forms when cold air moves into an area. Heavy rains often form along this.
What is a Cold Front?
400
Air at the center of this system rise. Air around the system moves in towards the center to take the place of the rising air. Cloudy and rainy weather are usually present in this type of system.
What is a Low-Pressure System.
400
These are used to collect and measure the amount of rain, snow, sleet, or hail. If the precipitation is solid, it is melted before it is measured.
What is a rain gauge?
500
Winds blowing across the ocean create a moving streams of water called this.
What is Ocean Currents?
500
This layer is the closest to Earth, where most weather occurs. It contains about 75% of the gases that make up the atmosphere.
What is Troposphere?
500
Sometimes when two air masses meet, neither mass moves forward. This type of front is called a what?
What is Stationary Front?
500
A useful tool for observing and forecasting weather.
What is Radar?
500
What temperature is the same for Fahrenheit and Celsius?
