Ch. 15-The Atmosphere
This atmospheric layer's temp. decreases with altitude with the gases mixing continuously
Narrow belts of winds that can reach 400 km/hr are called
This layer contains the ionosphere and temp. can be 1,000 degrees Celsius or higher
This layer is known as the middles layer where temp. decreases as altiude increases
What causes differences in air temperature at different altitudes?
The way gases absorb solar energy
What is the major source of human-caused air pollution?
Carbon monoxide, dust and smoke put directly into the air are known as
What is acid precipitation?
Rain, sleet or snow with high levels of acid
Identify the different gases found in the remaining 1% of other gases found in the atmosphere
argon, carbon dioxide, water vapor, methane
Electrically charges particles are called
Ovens that circulate hot air inside to cook food more quickly are called _______________ ovens
What causes differences in air pressure on Earth?
Unequal heating of Earth
Warm air rises because it is ____________ _____________ than cold air
Identify two examples of secondary pollutants
smog and ozone
Most thermal energy is transferred by
How long does it take the light from the sun to reach us?
Wind occurs because of differences in
What is the atmosphere made up of?
a mixture of gases (78% nitrogen, 21% oxygen and 1% other gases)
What can acid precipitation do to bodies of water surch as lakes and streams?
Acid shock or acidification to aquatic life
