Definitions
This is the amount of water vapor in the air in a particular parcel of air.
Humidity
What separates the Atmosphere layers?
Differences in temperatures
What oxygen is found in the Stratosphere?
Ozone
What powers the earths cycle?
Energy from the Sun
Dew point is the temperature at which condensation begins?
True or False
True
This is defined as the state of the atmosphere at some place and time, usually expressed in terms of temperature, air pressure, humidity, wind speed and direction, precipitation, and cloudiness.
Weather
Which layer of the atmosphere protects us from meteors?
Mesosphere
Which layer has the lowest air pressure?
Thermosphere
Which air is most dense?
Cold air/ Warm air
Cold Air
What is Wind?
Wind is air moving from an area of high pressure to an area of low pressure.
When warm air and cool air collide (differences in air pressure)
This is what the weather is like in a particular region or area over a long period of time. For example, Iceland has a cold, windy and cloudy climate. This doesn’t mean that they don’t have occasional warm sunny days. But those days are outnumbered by the cold, cloudy ones.
Climate
Which layer of the Atmosphere is where weather occurs?
Troposphere
What are the two most common gases found throughout all the layers?
Nitrogen & Oxygen
What causes clouds to form?
When the invisible water vapor in the air condenses into visible water droplets
What are Convection Currents?
Warm air rises. As it rises high into the atmosphere, it begins to cool, which therefore causes it to sink.
Can be the most intense storms on Earth. This is a system of winds rotating counterclockwise in the Northern Hemisphere around a low-pressure center.
Cyclones
Name the layers of the Atmosphere?
Stratosphere
Mesosphere
Thermosphere
Troposphere
Exosphere
Which layer of the atmosphere contains most of the gases on earth and why is this important?
Troposphere and it is important because this is where we live and the only layer that has enough gases for us to breathe.
Can you draw the symbols for warm front/ cold front?
The difference between a warm front in a cold front is that a cold front moves faster than a warm front. Warm front comes in slowly. When a cold front comes in, it quickly pushes the warm air upwards. When a warm front comes, it slowly pushes over the cool air.
The essential ingredients for a thunderstorm are....
warm, moist, unstable air that is forced to rise up either by convection, convergence or weather fronts.
This refers to a significant and sustained (over decades or longer) change from one climatic condition to another.
Climate Change
Why is the Atmosphere important?
Contains oxygen
Traps heat
Protects us from the suns uv rays
How do air masses flow?
From areas of high pressure to area of low pressure
What is a front? List the four different types of fronts we discussed?
A front is the boundary where two different air masses meet?
Cold, Warm, Occluded and Stationary.
What causes Weather?
Is caused by the heat of the sun and the movement of air.
Other factors that influence weather: Latitude, elevation, ocean currents, living close to a body of water or mountains. Large landmasses
