The diagram below shows a student’s model of the water cycle.
In which layer of the atmosphere does the process shown actually occur?
mesosphere
stratosphere
troposphere
thermosphere
Which best describes the temperature change that occurs as elevation increases within the troposphere?
Temperature increases as elevation increases.
Temperature decreases as elevation increases.
Temperature is random as elevation increases.
Temperature remains constant as elevation increases.
When cold air is at the tops of mountains, the air
will flow toward areas of lower pressure in valleys.
will flow toward areas of higher pressure in valleys.
is considered to be less dense than warmer air.
is considered to be free of oxygen atoms.
Which best describes the cause of wind?
Wind occurs when the movement of water on Earth’s surface causes uneven air currents creating conduction.
Wind occurs when the uneven heating of Earth’s surface causes air to heat and cool creating convection.
Wind occurs when the rotation of Earth along its axis creates movement of air currents.
Wind occurs when the tilt of Earth creates uneven movement of air currents.
The saturation of surface rock with oxygen early in Earth’s history reflected a change in Earth’s atmosphere. This change directly made which life process possible?
photosynthesis
nitrogen fixation
sulfur reduction
aerobic respiration
In which layer of Earth’s atmosphere does weather occur?
mesosphere
stratosphere
thermosphere
troposphere
Earth’s atmosphere is mainly composed of which gases?
hydrogen, helium, oxygen, and argon
nitrogen, oxygen, argon, and carbon dioxide
nitrogen, hydrogen, argon, and carbon dioxide
helium, hydrogen, oxygen, and carbon dioxide
Which BEST explains why air temperatures near mountaintops are often much colder than air temperatures near sea level?
ABC.DThe lack of vegetation at se
Large amounts of snowfall decrease the temperature.
Air near mountaintops is less dense.
Strong winds near mountaintops decrease temperatures
The lack of vegetation at sea level allows the ground to absorb more heat.
Which best describes why commercial jets fly in the lower stratosphere?
ABCD
This keeps the jet engines cool.
Rising air decreases the chance of turbulence.
Increased air molecules make for better air circulation.
Decreased cloud coverage reduces friction on the wings.
Which of these statements BEST describes temperature as elevation in the atmosphere increases?
Temperature remains constant with elevation in the thermosphere.
Temperature remains constant with elevation in the mesosphere.
Temperature generally decreases with elevation in the stratosphere.
Temperature generally decreases with elevation in the troposphere.
One substance found on Earth is more stable as an elemental gas than as part of a solid compound. As a result, this substance is very abundant in the atmosphere. Which substance exhibits these traits?
argon
chlorine
nitrogen
oxygen
Which two things interact MOST in the water cycle?
oceans and the Moon
oceans and the Sun
lakes and the Moon
lakes and the Sun
Which is the most likely cause of tropical storms?
Water runoff from the land fuels storm clouds.
High-pressure air causes storm clouds to form.
Sea breezes close to shore push storm clouds together.
Warm water evaporates, rises quickly, and interacts with a colder air mass.
Which combination of atmospheric conditions would most likely increase the chances for heavy rains in an area?
ABCD
low-pressure system and warm, dry air masses
low-pressure system and warm, wet air masses
high-pressure system and warm, dry air masses
high-pressure system and warm, wet air masses
Why do hurricanes typically break down once they make landfall?
The temperature is too warm to maintain the energy needed for the storms.
The temperature is too cool to maintain the energy needed for the storms.
The amount of moisture available is too little to provide fuel for the storms.
The amount of moisture available is too high to provide fuel for the storms.
Which important feature of the water cycle is missing from this figure?
the Moon
the Sun
rainbows
people
Which explains why most of the rain that falls comes from the ocean?
The majority of evaporation takes place over the ocean.
The majority of precipitation takes place over the ocean
Most rivers deposit freshwater into the ocean.
Most clouds form near or over the ocean.
This diagram shows the water cycle.
What event happens at Point 3?
Tides move the ocean water.
Waves move ocean water onto the shore.
Organisms in the ocean breathe oxygen in the water.
The Sun heats ocean water causing some to evaporate.
Which best describes water moving from land of higher elevation into a river or stream?
condensation
evaporation
precipitation
runoff
Which is needed for hurricanes to form off the west coast of Africa?
very shallow water
very deep water
moving water
warm water
Which relationship results in the highest level of evaporation from Earth’s water reservoirs?
greatest surface area and most direct sunlight
greatest surface area and least direct sunlight
least surface area and most direct sunlight
least surface area and least direct sunlight
What are visible mixtures of tiny water droplets or ice crystals suspended in air?
clouds
dew
hail
sleet
