Intro to Energy
Energy is ________________.
What is the ability to cause change?
What is thermal energy?
What is the total kinetic energy of particles in a substance?
Explain what the atmosphere is.
What is a mixture of gases that surrounds Earth?
What is wind?
What is the movement in air caused by differences in air pressure?
What is the difference between heat and thermal energy?
What is temperature is the average kinetic energy, whereas thermal energy is the total?
Kinetic energy is ____________.
What is the energy of motion?
Explain what conduction is.
What is conduction is the transfer of energy from one object to another through direct contact?
Explain what air pressure is.
What is air pressure is the measure of the force with which air molecules push onto an area of a surface?
What is the Coriolis Effect?
What is the apparent curving of the path of wind due to the Earth's rotation?
How is a convection current similar to wind?
What is they both occur because of differences in density?
Potential energy is ____________.
What is the energy of position, condition, or chemical composition?
Explain what convection is.
What is convection is the transfer of energy through any fluid by means of heat?
What is thermal expansion?
What is the increase in volume and decrease of density due to an increase in temperature?
What are Global winds?
What are wind systems that occur at or near Earth's surface?
What is heat?
What is the energy transferred between two objects at different temperatures?
What does the law of conservation of energy state?
The law of conservation of energy states energy cannot be added or lost, it simply changes forms.
Explain what radiation is.
What is radiation is the transfer of energy through electromagnetic waves (no direct contact and no particles)?
Explain what a convection current is.
What is the movement of matter due to differences in density, usually occurring in fluids?
What are jet streams?
What are narrow bels of high-speed winds that blow from west to east?
What is the main source of energy on Earth?
What is the Sun?
Name four different types of energy.
What are the potential, kinetic, thermal, chemical, mechanical, heat, sound, electromagnetic, electrical, and nuclear? (answers may vary).
Explain the difference between heat and temperature.
What is temperature is the average kinetic energy of heat whereas heat is the total kinetic energy of particles?
What is specific heat?
What is a property used to describe rates at which materials become warmer or cooler?
What are global winds?
What is the movement of air over short distances?
Heat moves from _________ to ______________.
What is heat moves from hot to cold?
