What is the name of the scientist who studies and predicts the weather?
meteorologist
100
What is the layer of the atmosphere where the ozone is found?
stratosphere
100
What is the type of cloud that usually brings heavy rain?
cumulonimbus
100
A town's weather is rainy and cool. What kind of air mass is most likely causing this weather?
cold and humid
100
Which weather tool measures temperature?
thermometer
200
What is the average temperature and precipitation in the same place over a period of time?
climate
200
In which way are greenhouse gases beneficial (good)?
They help keep Earth warm.
200
What is the best way to describe stratus clouds?
low and gray
200
Which type of front brings in light, steady rain?
warm front
200
Which weather tool measures precipitation?
rain gauge
300
What is humidity?
The amount of water vapor in the air.
300
What are the four layers that make up the Earth's atmosphere?
thermosphere, stratosphere, mesosphere, & troposphere
300
Explain the sun and its important roll in weather.
The sun is the energy source that drives the water cycle and forms all weather.
300
Explain the differences between different types of air masses.
Air masses that form over land are dry, air masses that form over water have a high humidity because of the evaporated water in the mass. Air masses that form over hot areas have a hotter temperature, air masses that form over cold areas will have a cooler/colder temperature.
300
Which weather tool is used to measure air pressure?
barometer
400
Name two types of precipitation.
sleet, hail, etc.
400
What layer of the atmosphere is the hottest?
Thermosphere
400
When water evaporates, it becomes water vapor. What happens when water vapor condenses in the air?
The water vapor forms clouds.
400
Explain what happens with the warm and cold air masses is a warm front.
A cold air mass is in the area. A warm air mass slowly moves into the area and creeps over the cold air mass. The warm air mass then rises and creates a slow steady rain.
400
What does a hygrometer measure?
humidity
500
Explain how a wind/weather vane works and what it measures.
The wind vane will spin, pointing the the direction that the wind is blowing. If the wind is blowing north, the arrow will point to the north.
500
Name at least two layers of the atmosphere and give two facts for each.
Troposphere - weather, airplanes, closest to the Earth Stratosphere - ozone, some planes Mesosphere - coldest layer, middle layer, weather balloon Thermosphere - hottest layer, farther from Earth, Northern lights
500
Explain what happens during evaporation.
Earth's fresh water is always being recycled. Heat from the sun causes fresh water to evaporation from the oceans, leaving salt behind. This water then forms condensation in the clouds.
500
In a two-story building, which floor do you think would be the warmest? Explain your reasoning.
The warmest level would be the upper level. This is because warmer air rises due to the particles of air being farther apart.
