Weather 1
four basic elements of weather?
temperature, wind, humidity, precipitation
what four forms can precipitation fall on the ground?
rain, snow, sleet, hail
__________ can use scientific data from the atmosphere to predict the weather
meteorologists
thermometer
measures temperature in degrees celcius
The increase in temperature causes some of the water to change into water vapour. This is called?
evaporation
temperature
the amount of heat in the air
rain gauge
measures the precipitation in millimetres
What is a weather pattern?
It is a pattern of temperature, humidity, wind, and precipitation
what are the two components of wind?
wind speed, wind direction
The humid air rises through the atmosphere and cools until it's very cold. Some of the water vapour changes back to water drops or ice crystals. This is called?
condensation
wind
the movement in the air
clouds and precipitation are produced by the ______ ?
water cycle
What are the three main climate zones on the Earth based on temperature?
cold climate zone, temperature climate zone, hot climate zone
wind direction
caused by air moving from an area of high pressure to an area of low pressure
lots of water drops and ice crystals together form ______
clouds
precipitation comes from water in clouds and most precipitation starts as _______
ice
temperatures on the Earth are increasing quicker than before because human activity is changing the composition of the atmosphere. What is this?
global warming
weather vane
shows wind direction using the cardinal points
when the clouds become heavy, gravity pulls them down to Earth. This is called?
precipitation
precipitation
water in liquid or solid form that falls from the air to the ground
What is the water cycle?
water evaporates from the surface of the earth, then condenses to form clouds, falls back down as precipitation and collects again on the surface of the earth. It is a continuous process
the ______ (distance from the Equator) and __________ of a place influence the climate zone it's in
latitude, altitude
anemometer
measures wind speed in kilometres per hour
Some precipitation falls directly into the sea and some runs off the land into rivers and groundwater. This is called
collection
