|
what are the layers of the atmosphere? |
troposphere, stratosphere, mesosphere, and thermosphere |
|
|
water cycle |
evaporation, condensation, precipitation, and run-off |
|
|
name all the air masses |
mP (maritime polar), mT (maritime tropical), cT (continental tropical), cP (continental polar) |
|
|
maritime tropical (mT) |
form over water, warm, moist |
|
|
maritime polar (mP) |
form over water, cold, moist |
|
|
continental tropical (cT) |
form over land, warm and dry |
|
|
continental polar (cP) |
form over land, cold, dry |
|
|
cold front |
heavy, brief precipitation and storms, afterwards air is calm and cool, warm air rises above it |
|
|
warm front |
brings hours of steady light rain or snow, warm air follows, pushes into and over the cold air mass causing a warm air mass |
|
|
stationary front |
when two air masses push against each other without moving |
|
|
high pressure |
clear skies and calm air, rotates clockwise |
|
|
low pressure |
causes stormy weather, cloudy, cool, wet song winds, rotates counterclockwise |
|
|
storm |
a violent disturbance in the atmosphere |
|
|
thunderstorms |
heavy rains accompanied by thunder and lightning, forms at cold fronts, warm humid air rises rapidly |
|
|
hurricanes |
forms over low pressure systems, gets energy from warm humid air |
|
|
blizzard hurricanes |
similar to hurricanes with strong winds but at colder temperature with blowing snow (basically a colder hurricane) |
|
|
eye of the storm |
the center of the hurricane, winds are calm and the sky is clear in the eye |
|
|
how do hurricanes move? |
they rotate around the eye in a counterclockwise direction |
|
|
what are some things you can do to prepare for a hurricane? |
-evacuate if necessary -water -non-perishable foods -flashlights -radio -batteries |
|
|
tornadoes |
rapidly whirling, funnel shaped cloud that reaches down from a storm cloud and touches Earth's surface |
|
|
when do tornadoes from? |
in the spring and summer in the late afternoon |
|
|
what front does a tornado form at? |
cold front |
|
|
where do tonadoes form? |
by the Gulf of Mexico and meet cold, dense air |
|
|
what should you do if a tornado is going to approach your city/state/town/ |
-get away from and doors or windows -lie under a heavy piece of furniture |
|
|
when does a tornado get weaker? |
when it touches land |
|
|
where does a tornado get its strength from? |
the ocean |
|
|
what is the instrument used to locate and identify storms that might produce tornadoes? |
doppler radar |
|
|
are tornadoes occur common in New York? |
no, because we are not that close to the tornado alley |

|
which layer of the atmosphere is where the space shuttle orbits? |
thermosphere |
|
|
transpiration |
the process where plants absorb water through the roots and then give off water vapor through pores in their leaves.
|
|
|
as a person climbs a mountain the pressure of the air will... |
decrease (will have less air) |
|
|
condensation |
liquid to gas |
|
|
what is a direct result of evaportion and transpiraton? |
moisture enters the atmosphere |
|
|
precipitation |
any type of liquid or solid sleet that falls to the earths surface, such as rain, snow, or hail |
|
|
what is air pressure measured with? |
barometer |
