Questions with Certified for Accuracy Answers
2024/2025
This gas is generally not reactive and is the most abundant in the atmosphere. - correct
answer Nitrogen
This gas is used by plants to make organic compounds. - correct answer Carbon
Dioxide
This gas also exists as a solid and liquid at Earth temperature and cycles between the
atmosphere, land, and oceans. - correct answer Water Vapor
Describe how and why air density changes with changes in altitude. - correct answer
Air density decreases with an increase in altitude because air particles have mass and
are pulled down by Earth's gravity.
Density is defined as - correct answer mass divided by volume.
Nitrogen is about _____ of the Earths atmosphere - correct answer 78%
A mechanical wave cannot travel through a - correct answer vacuum.
In which layer is the ozone layer located? - correct answer Stratosphere
Where does Earth's weather happen? - correct answer Troposphere
The troposphere is - correct answer the densest of the atmospheric layers.
,The exosphere is the least - correct answer dense atmospheric layer.
The International Space Station orbits Earth within the - correct answer thermosphere.
This is the coldest layer, with temperatures down to -90°C (194°F). The air is very thin,
but still thick enough to burn up meteors. - correct answer Mesosphere
Temperatures are very high here, although the density of air molecules is very low. The
International Space Station orbits in this layer. - correct answer Thremosphere
The air is very thin here. A vacuum exists above this layer. - correct answer exosphere.
Sound waves cannot travel in a vacuum because - correct answer they are mechanical
waves
Atmospheric pressure increases as humidity - correct answer decreases.
Temperature decreases with altitude in the - correct answer troposphere.
The warm, moist air has a lower pressure and will - correct answer rise above the cold,
dry air.
Air pressure decreases with - correct answer temperature and humidity, so a warm,
moist air mass will have a lower pressure than a cold, dry air mass.
A pure substance contains - correct answer a single type of element or compound.
Warm air is less dense than - correct answer cold air
Wind strength depends on differences in - correct answer air pressure
, Which of the following factors MOST DIRECTLY affect the strength and direction of
winds? - correct answer differences in air pressure and Earth's rotation
Because of the tilt of Earth, different latitudes on Earth experience different - correct
answer temperatures
These prevailing winds were originally blowing from the equator toward the - correct
answer South Pole.
prevailing winds - correct answer get deflected from north-south direction, due to the
Coriolis effect, which exists because of Earth's rotation.
Which statement describes the trade winds? - correct answer The trade winds travel
toward the low-pressure system near the equator but veer westward because of the
Coriolis effect.
As warm air rises it tends to - correct answer cool and become more dense
The largest reservoir(s) of freshwater (non-salt) on Earth is (are) - correct answer
Glaciers and ice caps
The water cycle is driven by - correct answer solar energy and gravity.
When a cloud forms water vapor condenses - correct answer which releases heat
Which of the following processes absorb heat and release water vapor to the
atmosphere? - correct answer Both evaporation and transpiration absorb heat to
convert liquid water to water vapor.
Condensation is a phase change from - correct answer gas to liquid.
