Exam 3 Flashcards
______ provides the energy that drives Earth’s weather.
The radiant energy of the Sun.
What kind of system is Earth’s climate and why?
It is an open system because the Sun’s energy comes from outside the system.
Where does the argon in Earth’s atmosphere come from?
The radioactive decay of unstable isotopes in Earth’s crust.
Where does carbon dioxide in the atmosphere come from?
From animals respiration and from the burning of fossil fuel.
Where does atmospheric oxygen come from?
cyanobacteria and plant photosynthesis.
Overall, which of the following atmospheric gases is the MOST abundant gas in the Earth’s atmosphere?
Nitrogen
Overall, which of the following atmospheric gases is the LEAST abundant gas in Earth’s atmosphere?
Carbon Dioxide
Anthropomorphic (man-made) activities are measurably adding more of this greenhouse gas to Earth’s atmosphere over time and as this happens it traps more heat in Earth’s atmosphere, causing the phenomena of global warming.
Carbon Dioxide
The ozone of the famous ozone layer that blocks much of the Sun’s harmful ultra-violet radiant energy from reaching the surface of the Earth is a tri-atomic molecular form of ______.
Oxygen
Where is the ozone layer located?
IN the Earth’s stratosphere (the lower stratosphere)
Most of the mass of Earth’s atmosphere and most of its weather happens in the layer of the atmosphere called the _________.
The Troposphere
The _______ is in the upper atmosphere and consists of charged atoms of atmospheric gases formed by the Sun’s radiant energy. It is where the aurora happens and it reflects certain frequencies of radio wave, such as shortwave and the AM radio band, back to the ground to enable radio broadcasts using those frequencies to be received over the horizon from the broadcasting station.
The Ionosphere
The part of the Earth that rotates the fastest is _______?
The Equator
Most storms move from west to east across Kansas because we are in the ____________.
The Prevailing Westerlies
Which of the following is the most accurate description of a monsoonal climate?
A warm, humid climate in the summer and a cool, dry climate in the winter
Air masses moving north or south from the Earth’s Equator are deflected to the _________; air masses moving toward the Earth’s Equator from the north or south are deflected to the __________
Defected to the east; deflected to the west
What has to rotate the fastest to complete a revolution in 24 hours?
The Earth’s Equator
the influence of the Earth’s rotation on movements across its surface
The Coriolis (Momentum) Effect
Anticyclones are ______ pressure areas, while cyclones are _______ pressure areas.
high pressure areas; low pressure areas
An anticyclone is Earth’s northern hemisphere rotates ________; a cyclone in Earth’s northern hemisphere rotates ___________.
clockwise; counterclockwise
