A high pressure area will most likely result in which type of weather? S6E4.d
stormy weather
clear weather
cloudy weather
snowy weather
Which situation best describes how a thunderstorm is formed? S6E4.d
Thunderstorms typically occur, when warm, moist air meets cool, dry air.
This is the result of incorrectly thinking air masses of different temperatures do not need to collide in order for thunderstorms to be likely.

How do weather fronts affect the formation of tornadoes? S6E4.d
Tornadoes can form when one weather front moves in a circle.
Tornadoes can form when one weather front reverses direction.
Tornadoes can form when two weather fronts pass one another.
Tornadoes can form when two weather fronts move into one other.
Mrs. Beavers' science class notices that a high pressure system bringing cold air is set to move into Locust Grove as the cold air enters the state, what will most likely occur? S6E4.d
Storm clouds will form.
There will be little to no wind.
There will be light rain.
The temperature will rise.
What are the conditions that will cause a thunder torm to form? S6E4.d
in the center of a large mass of cold, dry air
in the center of a large mass of warm, humid air
where two masses of warm, humid air collide with each other
where a warm, humid air mass collides with a dry, cold air mass
Read the passage about Tornado Alley.
Tornado Alley
The Midwestern United States is home to "Tornado Alley," a portion of Texas, Oklahoma, Kansas, and Nebraska commonly plagued with powerful and plentiful tornadoes. Tornado Alley is located at a point where the jet stream drives cool, dry, high-pressure air masses from the deserts and mountains of the West toward the East Coast.
What type of air mass do high pressure fronts collide with to create the tornadoes along Tornado Alley? S6E4.d
dry, cool, high-pressure air masses from Alaska
moist, cool, low-pressure air masses from Canada
moist, warm, low-pressure air masses from the Gulf of Mexico
dry, warm, high-pressure air masses from the Atlantic Ocean
Why does warm air rises? Because it
S6E4.d
has a lower density and pressure than cool air.
lacks density.
has a higher density than cool air.
is not affected by pressure.
Aiden and his family are listening to the weather report. The local meteorologist states: "There is a large patch of cool, dry air coming down from the north, and that is going to collide with warm, moist air coming from the south. We expect to see a lot of wind shear when these two air masses collide." Should Aiden and his family be concerned about a tornado forming? Why or why not? S6E4.d
Yes, because the cool, dry air will quickly rise when it meets the warm, moist air and create a vertical vortex that may lead to a supercell thunderstorm and a tornado.
No, because tornadoes only form out of thunderstorms that are created when two masses of warm air collide.
Yes, because strong wind shear will create a horizontal vortex and the warm, moist air will create an updraft that may lead to a supercell thunderstorm and a tornado.
No, because tornadoes cannot form out of thunderstorms that are created in the presence of any wind shear.
The weather is most likely to be clear and sunny?
in a low pressure system
in a high pressure system
at the edge of cold front
at the edge of warm front
On the coast of California, warm air usually picks up water vapor over the Pacific Ocean. What will happen when the warm, moist air moves inland over hot, dry land? S6E4.e
The warm air will become cool, causing water vapor to evaporate and be absorbed by the land.
The warm air will rise, causing water vapor to evaporate from the air and generate winds.
The warm air will rise, causing water vapor to condense and form clouds.
The warm air will sink, causing water vapor to condense and form snow.
An ocean allows a hurricane to grow by supplying it with
salt from hot waters.
oxygen from cool waters.
snow from freezing waters.
water vapor from warm waters.
The energy that powers a hurricane comes from
S6E4.e
from funnel clouds
outside a stationary front
outside subliming water
from warm and moist air
