2024-2025 ACTUAL EXAM WITH UPDATED QUESTIONS AND
VERIFIED ANSWERS
A mechanical wave cannot travel through a - ANSWER-vacuum.
In which layer is the ozone layer located? - ANSWER-
Stratosphere
Where does Earth's weather happen? - ANSWER-Troposphere
The troposphere is - ANSWER-the densest of the atmospheric
layers.
The exosphere is the least - ANSWER-dense atmospheric layer.

The International Space Station orbits Earth within the -
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. - ANSWER-Mesosphere
Temperatures are very high here, although the density of air
molecules is very low. The International Space Station orbits in
this layer. - ANSWER-Thremosphere
The air is very thin here. A vacuum exists above this layer. -
ANSWER-exosphere.
Sound waves cannot travel in a vacuum because - ANSWER-they
are mechanical waves

Atmospheric pressure increases as humidity - ANSWER-
decreases.
Temperature decreases with altitude in the - ANSWER-
troposphere.
The warm, moist air has a lower pressure and will - ANSWER-rise
above the cold, dry air.
Air pressure decreases with - 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 - ANSWER-a single type of element or
compound.
, 4|Page
Warm air is less dense than - ANSWER-cold air
Wind strength depends on differences in - ANSWER-air pressure
Which of the following factors MOST DIRECTLY affect the
strength and direction of winds? - ANSWER-differences in air
pressure and Earth's rotation
Because of the tilt of Earth, different latitudes on Earth experience
different - ANSWER-temperatures
These prevailing winds were originally blowing from the equator
toward the - ANSWER-South Pole.
