Weather 2
what is weather
conditions on earths atmosphere at a certain time and place.
Define evaporation
when water changes from a liquid to a gas, this is initiated from heat from the sun.
how is a cold front represented on a weather map vs. a warm front.
cold fronts have blue triangles, while warm fronts are red half circles.
what tool is used to measure temperature? and what do we call the units we measure in?
thermometer, degrees
what does a barometer measure?
air pressure
Which layer of earths atmosphere does weather occur?
Troposhere
define condensation
water changes from a gas into a liquid, forming water droplets, an accumulation of water droplets form clouds.
The place where two air masses meet is called a ...
front
define updraft
warm air that moves up instead of sideways.
what is a cumulus cloud? draw and explain
fluffy clouds, flat on the bottom, showing fair weather
Give 4 examples of severe weather events
hurricanes, tornadoes, snowstorms, twister, tsunami,ect.
define the water cycle
The movement of water into the air as water vapor and back to earths surface as precipitation
what weather events take place along fronts?
storms, cloud formation and precipitation
how does hail form?
hail forms when drops of rain freeze in the clouds and are carried higher into the clouds, freezing over and over, until too heavy then they fall as precipitation.
what does cumulonimbus clouds indicate?
tall clouds that bring thunderstorms.
what causes weather ?
Weather conditions like: temperature, humidity, wind and air pressure.
why is the water cycle important/what does it do?
the water on earth is constantly changing from one form to another, in a continuous cycle, without it we have no water.
what is an air mass? Describe the types( 4)
an air mass is a large body of air that has the same amount of temperature, air pressure, and moisture,
1.Warm /2.Cold
3. Moist/Dry
how does a warm front form?
when warm air mass pushes into a cold air mass
what is the difference between an anemometer and a wind vane ?
Anemometer measures the speed of wind, while a wind vane measures wind's direction.
what is the difference between weather and climate?
weather is the conditions of earths atmosphere at a certain time and place. Climate is the usual weather conditions of a place over an extended amount of time.
so one changes frequently, while the other is more consistent based off of geographic location.
Explain all the steps of the water cycle in order of occurrence
excess water flows off the surface of earth/mountain as runoff, collects in a body of water (lake, ocean, stream ect.)heat from the sun causes evaporation to occur, water droplets condense in the clouds until they become too heavy and fall as precipitation. the cycle repeats
Most changes in weather happens when...
one air mass moves into a place and pushes out another air mass
meteorologists measure ..
the conditions near earths surface and high in the atmosphere
Name all the tools a meteorologist might use to predict weather
thermometer, rain gage, barometer, anometer, wind vane, radar, satellite and computers
