c. by convection
d. by transpiration
c. by convection
a. foggy
b. heavy rain
c. clear skies

c. clear skies
This type of breeze blows during the day and the land is warmer than the ocean because it is more dense and absorbs heat energy faster. What breeze is being described.
Sea breeze
What is climate?
a. the current temperature and wind speed
b. the amount of water vapor in the air
c. the cloud cover and wind direction
d. the average precipitation and temperature in a given area
d. the average precipitation and temperature in a given area
During the Jet Stream if it dips below NC what weather/air would you expect?
Which will be an effect of a warm front moving into an area?
a. it rains before the front. rain stops during the front. it rains again after the front
b. clouds form before the front. there are thunderstorms during the front. the temperatures drop after the front.
c. it is windy before the front. skies clear during the front. air pressure drops after the drop
d. clouds form before the front. there are rain showers during the front. temperatures will rise after the front
Read the weather chart:

Chance of rain: low c. rainy
d. sunny
D. sunny
Which cloud type is low level, flat and dense, and looks like a blanket covering the sky?
Stratus
A student wants to predict weather for the next day, but can only choose one weather instrument. Which instrument would be the best to help predict a change in weather?
barometer
Gulf Stream
Describe a stationary front.
The boundary between a warm and cold air mass. A warm and cold air mass move in at the same time and stop moving.
After a rain, a puddle of water remains on a sidewalk. After a day of sunshine, the puddle is gone. What is the process called that is most responsible for the disappearance of the puddle?
Evaporation
True or false:
When air pressure drops, weather conditions get worse
True
A student is using a barometer and notices the numbers are rising, what type of weather should they expect?
clear skies and fair weather
prevailing westerlies moving from West to East.
How does the Gulf Stream affect weather patterns?
a. it warms air, which warms land along the coast
b. it blocks air, which stops wind from blowing
c. it cools air, which cools land along the coast
d. it moves air, which causes wind to blow
a. It warms air, which warms land along the coast
True or False:
When air pressure rises, weather conditions get worse.
False
What causes the change in seasons?
The tilt (axis) of the earth and the distance from the sun.
