To determine how fast fronts are moving.

Why does atmospheric temperature increase with altitude in the stratosphere?

because of the presence of the ozone layer

Answers

1
The three basic steps of the water cycle are:
infiltration, runoff, condensation
evaporation, perspiration, magnification
evaporation, sublimation, deposition
evaporation, condensation, precipitation
2
In what direction does air generally move in low pressure?
air generally remains in the same place
air swirls in a counter clockwise direction
air rises
air sinks
3
The current explanation of why the earth has water is:
Oceans came from volcanoes that melted glaciers
most of the water came from ice crystals from space
early earth's water came from asteroids, then comets
Earth's core was heated and released hydrogen and oxygen
4
Where can you find water in the gaseous states in the hydrologic cycle?
ground water
ocean
precipitation
evaporation
5
The average amount of water in the human body ranges from:
80% to 90%
44% to 51%
35% to 39%
65% to 74%
6
Where is air pressure lowest?
At sea level
On top of a skyscraper
At the bottom of the Grand Canyon
On top of Mt. Everest
7
It rained yesterday. Today it's sunny. Rain is predicted tomorrow. These are examples of:
Changes in the weather
Changes in neither weather nor climate
Changes in climate
Changes in both weather and climate
8
How does the atmosphere help sustain and protect life on Earth’s surface?
Greenhouse gases warm the air near the surface by 30o C.
All answers
The ozone layer shields us from harmful UV radiation.
Oxygen is a major component of the atmosphere.
9
The water cycle is driven (powered) by:
sun
gravity
clouds
the wind
10
Why are there trees on one side of the mountain, but not on the other?
The mountain blocks the wind preventing rain on the far side
The trees are on the side where birds drop pine tree seeds
The trees are on the side that is closest to water
No growth on the other side because it's steep and rocky.
11
What might cause a rain shadow to form?
A lake
A mountain
A city
A beach
12
Which picture shows Summer in the Southern Hemisphere?
Globe 2
Globe 4
Globe 1
Globe 3
13
Which of these statements about air density is true?
Air density is the same at all altitudes.
Air is less dense at high altitudes.
Air is less dense at low altitudes
Air is more dense at high altitudes
14
Which statement best describes what causes wind?
Air flowing from the equator outward
The pull from the moon's gravity
Air flowing from high pressure to low pressure
The strong currents in all the oceans
15
The amount of fresh water on earth is:
Much less than the amount of salt water
is NOT as drinkable as salt water
Much greater than the amount of salt water
is available (abundant) throughout the world
16
Air reaches saturation when:
Condensation equals evaporation
Evaporation happens faster than condensation
Condensation equals precipitation
Condensation happens faster than evaporation
17
Select the statement that best describes humidity.
Amount of pressure in the atmosphere measured by a barometer
Amount of sunlight radiation measured by a radiation meter
Amount of heat measured by a thermometer
Amount of moisture in the atmosphere measured by percent
18
A type of FRONT where one air mass collides with another causing brief heavy storms.
stationary front
cold front
warm front
occluded front
19
What is the best answer explaining how clouds are formed?
The temperature in the stratosphere is cold so water freezes
Water evaporates to form a vapor and condenses into clouds
Water condenses to form ice crystals and then evaporates
Water evaporates, then sticks together to form clouds
20
Why might a meteorologist compare a new weather map to one that is a day old?
What happens in one day, will likely happen again.
Past weather can accurately predict current conditions.
Meteorologists never compare current weather maps.
To determine how fast fronts are moving.
21
Why does atmospheric temperature increase with altitude in the stratosphere?
because is it less dense than the troposphere
because it is closer to the sun
because it is under a lot of pressure
because of the presence of the ozone layer
22
Earth rotates. How does this motion affect global winds?
Winds move straight from the poles to the equator
It causes the winds to curve
It causes the winds to blow
Winds move straight from the equator to the poles
23
What statement is NOT true about air pressure?
Air is more dense at sea level
Air has weight
Low air pressure is related to sunny days and clear skies
The higher up in the atmosphere, the less air pressure
24
What does the dew point measure?
The amount of high and low perssure
The temperature in the atmosphere
The percent of heat in the atmosphere
The amount of moisture in the air
25
Which number of the earth's revolution shows WINTER in the northern hemisphere?
Globe 4
Globe 2
Globe 1
Globe 3
26
Where can you find water in the liquid state in the hydrologic cycle?
precipitation
transpiration
ocean
evaporation
