Competency Certification Study Guide Exam
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.
