How Earth’s Atmosphere Gets Energy
Sun gives off energy.
Energy travels to Earth as electromagnetic radiation.
Some of the sun’s energy is reflected back into space or absorbed by gases or particles in the air.
The remaining energy is absorbed or reflected by the surface.
Much of the energy absorbed by the surface is radiated back into the atmosphere.
If the temperature is 68ºF, what is the temperature in degrees Celsius?
ºC = 20ºC
- Heat TransferConverting Units
Warm air expands, becomes less dense, and rises.
Cold, more dense air sinks.
Unequal heating of the atmosphere
Dense cold air has a higher pressure than less dense warm air. Wind blows from areas of higher pressure to areas of lower pressure.
How was the relative humidity affected by air temperature? Explain your answer.
- Water in the AtmosphereDetermining Relative Humidity
How does the water cycle work?
Water evaporates from the surface, condenses to form clouds, and falls to Earth as rain or snow.
What is relative humidity?
The percentage of water vapor in the air compared to the maximum amount air can hold at that temperature
How do clouds form?
Water in the air condenses on tiny particles in the air to form liquid water or crystals.
Can you determine weather conditions by looking at clouds?
Yes; each type of cloud is associated with a particular type of weather.
What You Know
Precipitation can be rain or snow.
Precipitation comes from clouds.
What You Learned
Sleet, freezing rain, and hail are forms of precipitation.
Droplets or ice crystals in clouds must grow heavy enough to fall through the air before precipitation occurs.
