Air Pressure
Does air pressure increase or decrease the higher you go up in the atmosphere?
Decrease
Weather occurs in what area of the atmosphere?
What is the troposphere.
What gas makes up about 21% of the atmosphere?
Oxygen
Which clouds that are high in the sky and made of ice crystals
Cirrus
Will you feel more air pressure at the top or the foot (bottom) of a mountain?
At the foot
Which layer protects us from meteors?
Mesosphere
What is the hottest layer of the atmosphere?
Thermosphere
Another name for elevation or the distance above sea level is known as
What is altitude.
Tell me one thing you know about stratus clouds.
-low level
-produce rain or snow
-fog is stratus
Which is heavier....cool air or warm air?
Cool air is heavier
What does the stratosphere have that protects us from the sun's radiation?
Ozone layer
Why is it harder to breathe when you're high up in the mountains?
There is less oxygen
What process turns liquid into gas and what powers this?
Evaporation, Sun
Which layer of the atmosphere has the most clouds?
troposphere
What is air pressure?
The force air applies on objects
What is ozone? Or how does it form?
A form of oxygen with 3 oxygen atoms in each molecule. OR it forms when lightning strikes oxygen (2 oxygen atoms bonded together)
Which type of air weighs less....warm air or cool air?
Warm air
Define Condensation.
Condensation is the process in which a gas turns into liquid.
Tell me two things you know about Cumulus clouds
-mid level
-look like cotton balls
-signal good weather
Why is air pressure higher at the foot of a mountain than at the top?
There is more air pressing down from the top.
The layers of the atmosphere starting closest to the Earth and going out are ...
What are the troposphere, stratosphere, mesosphere and thermosphere.
Why does cool air weigh heavier than warm air?
Warm air has more energy so the particles are moving faster and are further apart. Cool air particles are more dense and closer together.
Define Greenhouse Effect
The trapping of the Sun's energy by certain gases in the earth's atmosphere
How do clouds form?
Sun's heat causes water from oceans, lakes, rivers, etc to evaporate (turn to water vapor---gas form of water)
Water vapor cools and condenses (turns into liquid water drops) onto dust, smoke, and other particles
Millions of these particles form clouds
