Meteorology Test Flashcards
Why do temps vary?
- Land heats and cools more rapidly than water
- Geographic location/position(latitude)
- Altitude
Water freezes at..
0 degrees C and 32 degrees F
Water boils at..
100 degrees C and 212 degrees F
What causes the greenhouse effect to increase?
burning of fossil fuels- adds CO2 into air and contributes to Global warming
All of Earth’ energy from the sun is mostly..
reflected back into space
What happens when temperature drops below Dew point?
clouds form
What is in Acid rain?
nitrate and sulfate particles that come from the burning of fossil fuels/volcanoes
Acid rain is considered..
secondary pollution
What is air made up of?
78% Nitrogen(N), 21% Oxygen(O), 1% other and water vapor(clouds and precipitation)
What are the 2 thermometers?
Wet bulb and Dry bulb
How to find the Relative humidity
Take the difference of the wet and dry and go over, then go down to the dry bulb #
Energy trapped in the atmosphere due to..
Greenhouse Effect
Greenhouse gases lead to..
Global warming-
Global warming leads to..
climate change and rising sea levels
Fossil fuels(name them)
CO2, nitrates, NO2
Greenhouse gases
CO2, Methane, water vapor
Example of Conduction
spoon and hot pot
Example of Convection
lava lamp
Example of Radiation
Energy
T or F? Another term for Greenhouse Effect is Global Warming
FALSE
T or F? All objects at any temperature emit radiant energy
TRUE
T or F? The hotter a radiating body is the longer the wavelengths of maximum radiation it will produce
FALSE
Objects that are good absorbers of radiation are also good ______ of radiation
emitters
Hotter objects emit _____ total energy per unit area than objects do
more
3 things that that can happen radiation strikes an object
- radiation may bounce off without being absorbed or transmitted
- water and air are transparent to certain wavelengths of radiation
- some energy is absorbed
What percent of solar energy reaching the outer atmosphere is reflected or scattered back into space
29%
