Weather Fronts
Where are fronts located?
In between a hot and a cold air mass
The process where liquid water turns into water vapor and rises into the atmosphere
What is... Evaporation
What is precipitation?
Any type of falling water from the sky. (rain, hail, snow, sleet)
What is the cause of precipitation moving across the globe?
Wind
Which state of water has molecules that are moving the SLOWEST?
Solid (Ice)
What is the symbol for a cold front?
A line with triangles coming off of it
The term for any form of water that falls from the atmosphere to the Earth's surface, such as rain, snow, or hail
What is... Precipitation
This type of precipitation forms when water droplets freeze and fall as balls of ice during strong storms.
Hail
This factor affects how much water vapor air can hold, with warmer air holding more moisture.
Temperature
True or False. Water molecules attract one another.
True
Which type of front results in scattered clouds, light rain, and lasts for an extended period of time?
Warm front
The part of the water cycle involves water vapor cooling and changing back into liquid water or ice crystals, forming clouds
What is... Condensation
Before precipitation occurs, what stage of the water cycle must happen in the clouds first?
Condensation
This measurement describes how much water vapor is in the air compared to how much it can hold.
(Relative) Humidity
As water changes from being a solid, to a liquid, to a gas the molecules…
What is... Speed up and spread out
What is an air mass?
A large body of air with uniform temperature and humidity
The primary source of energy that drives the water cycle
What is... The sun
Precipitation and condensation happen when we have what temperature change?
(hot->cold or cold->hot)
Hot to cold
When air is forced up over mountains, this factor can increase precipitation on one side.
Elevation/ mountains
The motion of water molecules when heat (energy) is added to liquid water
What is... they move faster and spread further apart
As a cold front rolls through, what weather conditions could we expect?
Heavy rain, thunderstorms, large puffy clouds, short lived weather, cold temperatures
The body of water that is the largest reservoir of Earth's water
What is... the Oceans
Before precipitation can occur, water must first change from liquid to gas during this process.
Evaporation
Which type of ocean creates humid conditions with high precipitation rates?
Warm oceans/ currents
If we cool water vapor in the air slowly, what happens to it?
The molecules slow and turn into liquid form
