Weather Instruments
An instrument to record the amount of rainfall in a given area
rain guage
When air pressure goes down or low, the weather usually becomes this.
rainy, stormy, lousy
This part of the water cycle happens when the sun heats up water and it turns into a gas
evaporation
This common for of precipitation falls as liquid water from the sky
Rain
What is the main source of Earth’s weather and heat?
The Sun
An instrument for measuring temperature
thermometer
High air pressure usually brings this kind of weather.
sunny
After water vapor rises and cools, it turns into tiny droplets in the air in this process.
condensation
This frozen form of precipitation forms when raindrops freeze before hitting the ground.
Sleet
This happens when warm air rises, cools, and forms droplets in the sky.
clouds form
An instrument used to measure wind direction
Wind Vane
Air pressure is caused by the weight of the air pressing down on what?
The earth
Rain, snow, sleet, and hail are all examples of this step in the water cycle.
precipitation
This type of precipitation forms when updrafts carry raindrops upward into freezing temperatures multiple times.
This is the term used to describe the amount of water vapor in the air.
humidity
An instrument that measures wind speed
Anomometer
It often feels hotter on a humid day because sweat doesn’t do this as easily.
evaporate
This is when water flows over the land and back into oceans, lakes, and rivers.
Runoff
Snow is made of this state of water.
Solid
When the temperature of the air is higher, the air can hold more of this
An instrument that measures air pressure
Barometer
This is the type of air pressure system that is usually associated with cloudy, stormy, or rainy weather.
low pressure
This process returns water from plants back into the air
transpiration
Hail
When you go up in the atmosphere, the air pressure does this.
