-To measure the jet stream a weather balloon must go through
layers of the atmosphere. The weather balloons needs to be in the
stratosphere, where the jet stream is located. It must first pass
through the troposphere.
- Wheat requires hot temperatures and sufficient rain to grow. A
weather map can help the farmer decide where to buy land because
weather maps tell the temperatures and rainfall amounts. The farmer
could use the maps to predict the weather and decide where wheat has
the best chance of growing.
-A city near an ocean lacks fresh drinking water. You could use
the salt water because it could be converted into fresh water through
evaporation. You could build a factory that would evaporate water,
leaving the salt behind. The water vapor cools and becomes fresh
drinking water.
-Air pressure is higher at sea level and lower on a mountain top.
If you wonder whether air pressure affects the temperature at which
water starts to boil, you test your idea by using a thermometer to
measure the temperature of boiling water at sea level and at a higher
elevation. For example on a mountain, you could watch until the water
boils and then record the temperature. You would record just as the
water starts to boil at each height. Then you could compare the two
temperatures.
-When the atmosphere reaches 32 degrees Fahrenheit it will snow
or sleet.
-The weather forecaster said the the skies were clear, and the
barometer showed that the air pressure was rising. He will predict
the weather to be cold and fair.
-You would fly a kite in the troposphere.
-Rising water vapor turns back into a liquid when the water vapor
cools and condenses.
-The temperature is lower at the North pole than at the
Equator.
-Precipitation is another name for rain, sleet, hail, or
snow.
-Atmosphere is the air around the Earth.
-Condensation forms when water vapor cools.
-Air pressure is when the atmosphere is pressing down.
-Evaporation is the changing of a liquid into a gas.
-A thermometer is used to measure how hot or cold something
is.
- A barometer measures air pressure.
