WEATHER TOOL
What tool is used to measure air pressure?
Which layer of the atmosphere has weather?
Troposphere
What are the reasons for the seasons?
Earth's Tilt.
How do we know that air has mass?
It has matter and takes up space
Which Hemisphere is the United States located in?
The Northern Hemisphere
What tool is used to measure temperature?
A Thermometer
What layer of the atmosphere is the Ozone layer?
Stratosphere
When the North Pole is leaning toward the sun, is daylight shorter or longer?
Explain why.
Longer.
Because we receive sunlight at a direct angle.
Greenhouse gases trap heat in Earth's atmosphere.
Examples include: Carbon Dioxide, Water Vapor, Methane, Ozone
Using the Globe, distinguish the Northern Hemisphere from the Southern Hemisphere.
What separates them?
Norther Hemisphere - Top half
Southern Hemisphere- Bottom half
The equator
What tool is used to measure wind speed?
Wind meter
What is the job of the Ozone layer?
To protect us from UV radiation.
Describe the difference between rotation and revolution.
Use the Earth and Sun model to explain.
Rotation is when the Earth spins around one time. Rotation takes 24 hours.
Revolution is when the Earth revolves around the Sun. A revolution takes 365 1/4 days.
What are Permanent gases?
What is the difference between weather and climate?
Weather is the condition of the atmosphere at a given place and time.
Climate is the average weather for a given place.
What tool is used to measure humidity
Hygrometer
What is meteorology?
The study of the atmosphre
When the Earth is closer to the sun in distance, what season are we experiencing in the Northern Hemisphere and why?
Winter. Even though we are closer to the Sun in distance, we receive less solar energy because we are getting sun at an angle.
What are variable gases?
Gases that change in response to Earths environment.
Compare and contrast hurricanes and tornadoes.
Hurricanes- Form in water, have an eye, can last weeks, causes flooding
Tornadoes- Unpredictable, usually forms on land, can last minutes, high wind speed
Both causes destruction and have high wind( tornadoes much higher)
Name all FOUR weather factors
Temperature, humidity, air pressure, wind
What is the order of the layers of the atmosphere?
Starting from the layer closest to Earth.
Troposphere
Stratosphere
Mesosphere
Thermosphere
Exosphere
Explain the relationship between the Suns angles and solar energy?
You can use the globe to explain your answer
When the Sun hits Earth at shallow angle we receive less solar energy. (Winter)
When the Sun hits Earth at a direct angle it receives more solar energy. (Summer)
What percentage of the air is filled with Nitrogen?
78%
Explain why we have a leap year.
Earth revolution last 365 1/4 days.
Every 4 years that 1/4 makes up for an extra day. That day is added to February giving it 29 days.
