These steady winds flow from east to west between 30°N latitude and 30°S latitude.
What are trade winds?
Air pressure is greatest where?
A. At a mountain base /
B. On a mountain top /
C. In the stratosphere /
D. In the ionosphere
A. At a mountain base
Which type of energy is emitted from Earth’s atmosphere?
A. Ultraviolet radiation /
B. Visible radiation /
C. Infrared radiation /
D. Aurora borealis
C. infrared radiation
A diagram showing large bands of wind moving around Earth represents:
A. Air masses /
B. Global wind belts /
C. Inversions /
D. Particulate motion
B. global wind belts
Which helps protect people, animals, plants, and buildings from harmful air pollution?
A. Primary pollutants /
B. Secondary pollutants /
C. Ozone layer /
D. Air quality standards
D. air quality standards
This type of energy transfer carries the Sun’s thermal energy through empty space to Earth.
What is radiation?
In which layer of the atmosphere is the ozone layer found?
A. Troposphere /
B. Stratosphere /
C. Mesosphere /
D. Thermosphere
B. the stratosphere
Which statement best describes the Sun’s energy?
A. It is completely absorbed by the atmosphere. /
B. It is completely reflected by the atmosphere. /
C. It stays in space. /
D. It warms Earth, and Earth then transfers energy to the atmosphere.
D. It warms Earth, and Earth then transfers energy to the atmosphere.
Wind begins because the Sun heats Earth’s surface:
A. Equally everywhere /
B. Unequally /
C. Only at the equator /
D. Only during summer
B. unequally
Household cleaners and sprays can be a source of:
A. Ultraviolet radiation /
B. Indoor air pollution /
C. Radon /
D. Global winds
B. indoor air pollution
This type of heat transfer occurs when rising currents of warm air move energy through the atmosphere.
What is convection?
This is the lowest layer of Earth’s atmosphere and the layer where most weather occurs.
What is the troposphere?
This type of heat transfer happens when objects or particles touch one another directly.
What is conduction?
When air becomes warmer and less dense, it usually does this.
Sulfur dioxide and nitrogen oxides can react in the atmosphere and eventually produce this.
What is acid precipitation?
This narrow band of very fast winds is located near the top of the troposphere.
What is a jet stream?
This atmospheric layer sits above the troposphere and contains the ozone layer.
What is the stratosphere?
Visible radiation can be seen by humans. This type of radiation cannot be seen and is associated with heat.
What is infrared radiation?
Put these events in the correct order:
4 → 3 → 2 → 1
If many more trees were planted, what would most likely happen to the amount of carbon dioxide in the atmosphere?
It would decrease, because trees take in carbon dioxide during photosynthesis.
Radio waves can travel long distances by bouncing off electrically charged particles in this region of the atmosphere.
What is the ionosphere?
Name one important difference between the troposphere and the stratosphere.
The troposphere contains most weather, while the stratosphere contains the ozone layer.
Put these events in order:
3 → 4 → 1 → 2
Why does a sea breeze usually occur during the day?
Land heats faster than water, so warm air over land rises and cooler air from over the water moves toward land.
Name one way a person could help reduce particulate matter produced by transportation.
Examples include driving less, carpooling, walking, biking, or using public transportation.
