Thermal Energy
What is the main source of thermal energy on Earth?
To make wind, air moves from _________ pressure to ___________pressure.
HIGH to LOW
Why does the Earth have places with HOT temperatures, and places with COLD temperatures at the same time?
The Sun heats the Earth UNEVENLY.
Water that GAINS thermal energy (becomes hot) will move into the atmosphere through what process?
Evaporation
Water that evaporates from a solid/ice form directly to the atmosphere is called what? (mostly happens on mountain tops and the N. or S. poles)
Sublimation
When objects GAIN thermal energy, are they getting HOTTER or COLDER?
HOTTER
Hot air will _________________ due to its low density.
rise (go up)
When the wind blows in a circular pattern at high speeds on land, what is it called?
A tornado
Water that LOSES thermal energy (gets cold) due to rising up into the atmosphere, will go through what process?
Condensation (formation of a cloud)
In our classroom demonstration with the water in the bag, how did we make evaporation happen?
The LIGHT gave it heat, like the sun!
When matter LOSES thermal energy, what happens?
Cold air will ______________ due to its high density.
sink (go down)
When wind spins at high speeds over water, what is it called?
A hurricane
What supplies the energy/heat for evaporation?
The Sun
In our classroom demonstration with the water in the glass jar, how did we make condensation happen?
With the ICE on top, making it cold.
Radiation
Wind will curve in circular motions due to the Earth spinning. What is that called?
The Coriolis Effect
List 4 ways water can enter the atmosphere.
Evaporation, Transpiration, Perspiration, Sublimation
When water molecules join together in clouds, and become large enough for gravity to act upon them, what process happens?
Precipitation
When water soaks into the ground due to gravity, what is it called?
Infiltration
The Sun heats different parts of the Earth at different rates. What is this called?
UNEVEN heating
Due to a high amount of pressure, ___________ air can push ___________ air around.
COLD air can push WARM air
What is it called when hot rises and cold sinks?
(hot goes up and cold goes down)
Convection current
Water that enters the atmosphere by evaporating off of plants and leaves is called what?
Transpiration
Name 4 types of precipitation.
Rain, snow, sleet, hail
