Evaporation
When the sun heats up bodies of water and the molecules dance so fast that they turn into water vapor.
Condensation
Up in the clouds, the air is cold so that makes the molecules dance slower and turns back into liquid form.
Precipitation
The clouds are filled with so much liquid that it cannot hold it anymore and pours down to the ground. This includes sleet, hail, snow or rain.
Run off
Gravity causes liquid water to flow toward the sea
Transpiration
Water Vapor is realeased from stomata (holes) in plant leaves
Dew Point
The temperature at which water vapor in the air becomes saturated and water droplets begin to form.
Air Temperature
A measure of how cold or hot the air is around us, it is usually measured with °C.
Relative Humidity
The percentage of water vapor in the air compared to the maximum amount the air can hold.
Wind Speed
This is a measure of how fast the wind is going, it is measured with km/h.
Wind Direction
The wind in which it comes from it, so we name the wind after where it blows from.
Barometric pressure
Pressure caused by the weight of the atmosphere. It decreases with increasing altitude.
Anemometer
Measures wind speed
See how many turns it makes in one minute.
Thermometer
Measure air temperature
See how far up the liquid goes up the straw.
Barometer
Measures barometric pressure
If the indicator points to high, then there is good weather, low then there is going to be bad weather.
