Energy
the ability to cause change
What is energy?
areas of higher pressure to areas of lower pressure
How does air move?
increase in volume that results from an increase in temperature
What is thermal expansion?
the mixture of gases that surround Earth
What is the atmosphere?
the energy that an object has due to position, condition, or chemical composition
What is potential energy?
movement of air caused by the differences in air pressure
What is wind?
the energy that is transferred between objects that are at different temperatures.
What is heat
makes up 78% of Earth's atmosphere
What is nitrogen?
potential energy that affects an object's position
What is gravitational potential energy?
movement of air over short distances
local winds
different rates at which materials become warmer or cooler are due to a property called ______
specific heat
the measure of the force with which air molecules push on an area of a surface
What is air pressure?
takes place when energy changes from one form into another form
What is energy transformation?
at night, air along mountain slopes cool and move down into the valley
What is a mountain breeze?
glass, dry wood, plastic, paper, rubber
What are some examples of an insulator?
the measure of the AVERAGE kinetic energy of particles
What is temperature?
mechanical energy, sound energy, electromagnetic energy, electrical energy, chemical energy, thermal energy, nuclear energy
What forms can energy take?
during the day, the sun warms up air along mountain sloped faster than air in valleys, resulting in areas of lower pressure near the mountain tops
What are valley breezes?
radiation, convection, conduction
How is energy transferred?
the TOTAL kinetic energy of particles
What is thermal energy?
