Layers
What layer of the atmosphere contains jets, clouds, and mountains
Troposphere
What layer of the atmosphere has the oxone layer?
Stratosphere
Temperature __________________ with altitude in the troposphere and mesosphere, but _________________ with altitude in the stratosphere and thermosphere.
decreases, increases
What are the 3 main gases in the atmosphere?
Nitrogen, Oxygen, and argon/other trace gases
What is the greenhouse effect?
Which layer is where meteors burn up
What is the chemical composition of ozone
O3
What is air density?
how tightly packed air molecules
What percent of the Troposphere's air is nitrogen
78%
These are gases like water vapor, carbon dioxide, and methane that trap heat in the atmosphere.
How is each layer of Earth's atmosphere identified? By differences in...
MUST SAY AT LEAST 2/3
What does ozone gas do?
A layer of gas that protects us from harmful UV radiation.
What is the relationship between density, temperature, and altitude
Density decreases with increasing altitude because there is less air pressure, which increases temperature because warmer molecules spread out
Which gas is the least abundant
Carbon Dioxide
How do human activities cause climate change?
Burning fossil fuels and deforestation release excess greenhouse gases, intensifying the natural greenhouse effect and leading to a warmer planet.
Which layer has the least amount of air molecules
Exosphere
Tamara draws a picture showing four layers of Earth's atmosphere. She draws clouds in the mesosphere, a jet airplane in the stratosphere, an orbiting satellite in the thermosphere, and ozone in the troposphere.
Why does the air generally get colder the higher you go in altitude?
The air is less dense and holds less heat at higher altitudes, as it's farther from the Earth's surface which absorbs solar radiation
Draw a pie chart with the accurate compositions of the gases in the atmosphere
78%- nitrogen
21%- oxygen
1%- argon/trace gases
How does climate change affect the oceans?
Climate change can lead to ocean acidification and rising sea levels, affecting marine ecosystems and coastal communities.
Thermosphere
What is the name of the chemical that can break down ozone?
Chlorofluorocarbons (CFC)
True or False: Temperature always decreases as altitude increases
False; while it generally decreases in the lower atmosphere, there are layers like the stratosphere where it increases
What is a trace gas
A gas that makes up less than 1% of the air
What's the difference between global warming and climate change?
Global warming is the long-term heating of Earth's climate system, while climate change encompasses the broader range of changes happening to our planet, including temperature, precipitation patterns, and more
