ANSWERS|ALREADY GRADED A+
Describe how and why air density changes with changes in altitude. -
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 - ANSWER- mass divided by volume.
Nitrogen is about _____ of the Earths atmosphere - ANSWER- 78%
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 - ANSWERthermosphere.
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. - ANSWERMesosphere
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. - ANSWERexosphere.
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.
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.
prevailing winds - 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? - 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 - ANSWER- cool and become more dense
The largest reservoir(s) of freshwater (non-salt) on Earth is (are) -
ANSWER- Glaciers and ice caps
The water cycle is driven by - ANSWER- solar energy and gravity.
When a cloud forms water vapor condenses - ANSWER- which releases
heat
Which of the following processes absorb heat and release water vapor to
the atmosphere? - ANSWER- Both evaporation and transpiration absorb
heat to convert liquid water to water vapor.
Condensation is a phase change from - ANSWER- gas to liquid.
Evaporation is a phase change from - ANSWER- liquid to gas.
Rain falls back toward Earth's surface because of - ANSWER- gravity
