Vocab Part 1
The amount of water vapor in the air is called:
a. air pressure
b. humidity
c. front
b. humidity
The air that surrounds our planet is...
a. greenhouse effect
b. troposphere
c. atmosphere
c. atmosphere
What are the four layers that make up Earth's atmosphere?
a. thermosphere, stratosphere, mesosphere, ozone layer
b. thermosphere, barosphere, mesosphere, troposphere
c. thermosphere, stratosphere, mesosphere, troposphere
If the weather in a certain area is warm and dry with a stationary front nearby, what will the weather be like tomorrow in that area? Why?
a. It will be rainy and cold because of the cold front.
b. It will stay the same because of the stationary front.
c. It will be snowy and hot because of the warm front.
b. It will stay the same because of the stationary front.
What kind of changes in weather conditions can take place?
Why do these changes occur?
There are changes in air temperature, air pressure, wind speed and direction, and amount and type of precipitation.
These changes occur because of the sun's energy doesn't reach all areas of Earth with the same intensity.
An instrument that is used to measure air pressure is:
a. anemometer
b. barometer
c. stratosphere
b. barometer
What are air particles pressing down on a surface called?
a. air mass
b. air pressure
c. front
b. air pressure
Which of the following characteristics describe warm air?
a. It is forced upward by cooler air and exerts low pressure.
b. It is forced upward by cooler air and exerts high pressure.
c. It sinks and has high pressure.
A. It is forced upward by cooler air and exerts low pressure
If there is an area of land where a cold front will meet with a warm front, what do you think the weather will be like tomorrow? Why?
Since a cold front is going to meet a warm front, it will most likely rain because there will be more moisture(humidity) in the air.
Would there be wind without the sun? Why or why not?
No, because the sun's energy does not warm the Earth evenly. This causes some air to be warmer than other air, which results in areas of high and low pressure. When high-pressure air masses meet with low-pressure air masses, the wind blows.
What is a large body of air that has moisture content and temperature similar to the water or land over which it formed
a. air mass
b. front
c. greenhouse effect
a. air mass
What layer of the atmosphere is the closest to the Earth?
a. troposphere
b. stratosphere
c. atmosphere
a. troposphere
In which layer of the atmosphere does most weather occur?
a. stratosphere
b. troposphere
c. mesosphere
b. troposphere
How will winds during a cold front change while the cold front is passing through and after the cold front has passed through?
Winds will be gusty and shifting while passing. After the cold front has passed, the winds will be low.
How do our bodies and senses tell us about weather conditions that are happening or about to happen?
We ca feel temperature, wind, moisture with our skin, see rain, snow, clouds, changes in light, and the wind blowing things. We can also hear gusty wind, thunder, and rain falling.
What describes how heat from the sun is trapped in the atmosphere to warm the Earth?
a. troposphere
b. air pressure
c. greenhouse effect
c. greenhouse effect
What border is formed where a cold air mass and a warm air mass meet?
a. greenhouse effect
b. anemometer
c. front
c. front
What are two properties that can be used to describe air masses?
a. temperature and wind speed
b. temperature and cloud cover
c. temperature and moisture
c. temperature and moisture
How will the temperature in an area change AFTER a cold front has passed through the area?
The temperature will be lower than it previously was before.
Why aren't weather forecasts always accurate?
Because weather conditions can change unexpectedly. Air masses can form fronts, wind can change direction, and storms can appear.
The layer of the atmosphere just ABOVE most weather is called:
a. troposphere
b. stratosphere
c. atmosphere
b. stratosphere
The instrument used to measure wind speed is called:
a. anemometer
b. barometer
c. humidity
a. anemometer
Degrees, centimeters, and kilometers per hours are all forms of what?
a. measurements for weighing people
b. measurements for wind speed, temperature, and precipitation
c. measurements used for determining liquids
b. measurements for wind speed (km/hr), temperature (degrees), and precipitation (centimeters)
What will happen to rain while a cold front is passing through an area?
There will be heavy rains and possible thunderstorms.
