Layers of Atmosphere
This is the 4th layer of the atmopshere where the ISS orbits.
thermosphere
True or False, Too little Greenhouse Gases would not be a problem, and why
False, without the Greenhouse gases/Effect, the Earth would be in an ice age.
Where is the Ozone Layer found in the atmosphere?
What is the upper Stratosphere.
How does Global Warming happen?
What is when there are too many greenhouse gases in the atmosphere trapping too much Infrared (heat) radiation.
Where is the Ozone Layer the thinnest?
What is over the Poles, especially Antarctica.
The 3rd atmospheric layer, where most meteors burn up upon entering the atmosphere.
mesosphere
The energy emitted by the sun. This energy can be seen and felt as heat in the sun's rays
solar radiation
Why is this sub-layer necessary for life on Earth?
What is it filters out about 98% of harmful UV rays.
Since the Industrial Revolution what changes hae been occuring on Earth?
Increase in Carbon Dioxide levels in the atmosphere have led to increase in global warming
What chemical compound is solely responsible for Ozone Depletion?
What are CFC's
The lowest or 1st atmospheric layer, where most weather occurs, and where all life exists.
troposphere
The study of the Earth's atmosphere
meteorology
What are natural sources of greenhouse gases?
What are volcanic eruptions (releasing carbon dioxide and water vapor), decomposition of organic matter (producing methane), respiration from plants and animals (emitting carbon dioxide), wetlands (contributing to methane emissions), and the oceans releasing carbon dioxide
What are man-made sources of greenhouse gasses?
burning fossil fuels (coal, oil, natural gas) for electricity and transportation, industrial processes, agriculture, deforestation, and the release of chlorofluorocarbons (CFCs) used in refrigeration and air conditioning
What part of the Ozone depleting compound breaks off by sunlight and "attacks" the Ozone layer making a hole?
What is the Chlorine atom.
The highest or 5th atmospheric layer, where the atmosphere gradually fades into space. (most satellites orbit in this layer)
exosphere
What is the composition of Earth's atmosphere?
78% Nitrogen, 21% Oxygen, 1% trace gases
What are the 5 major ocean wide currents (gyres) that impact weather/climate?
North Atlantic, South Atlantic, North Pacific, South Pacific, and Indian Ocean gyres
What do we call the large-scale removal of vegetation that contributes to global warming?
deforestation
Around 75-85% of the Earth's air is found in the trophosphere, why?
Gravity holds most of the air near Earth's surface.
How is weather different from climate?
Weather refers to the current atmospheric conditions, while climate is the average weather pattern over a long period, usually decades, in a given area.
Why do we have seasons on Earth?
Earth experiences seasons because its axis is tilted as it orbits the sun, meaning different parts of the planet receive varying amounts of direct sunlight throughout the year; when the North Pole tilts towards the sun, it's summer in the Northern Hemisphere, and when it tilts away, it's winter.
These friendly farm animals contribute to global warming, what are they and what do they do?
What is Cow's belch 600 liters of methane a day.
Depleated ozone layer = _______ health effects
cataracts, weaker immune system, skin cancer, crops with lower yields, death of phytoplankton in the oceans disrupting food web (so less fish and other organisms to harvest)
