Temperature- a measure of the amount of
kinetic energy in a substance
Heat- a transfer of energy between two objects due to a difference in temperature Heat always moves from hot to cold
Temperature vs. Heat
Conduction Convection Radiation
3 Ways Heat can be Transferred
The transfer of heat (energy) from one
substance to another substance that is touching it It is most effective in solids, but can happen in liquids
Fun fact: Have you ever noticed that metals tend to feel cold?
Believe it or not, they are not colder! They only feel colder because they conduct heat away from your hand. You perceive the heat that is leaving your hand as cold
Conduction
The transfer of heat (energy) by the
movement of matter. Happens mostly in gas and liquids This happens with currents Colder matter (more dense) sinks below warmer
matter and pushed warmer matter up Have you ever heard of the saying “warm air
rises” Why does colder matter sink? (hint: use
kinetic energy, molecules, and density)
Convection
Electromagnetic waves directly transport
energy through space Done without the help of fluids or solids Travel in waves

Why you use a hot pad when touching a metal pot that has been on the stove
A. Convection B. Conduction C. Radiation
This causes an entire pot of hot what to boil

A rain shadow is a result of this type of heat transfer.

Land and sea breezes are caused by this. (Actually all winds are)

This is why a metal spoon gets warm when placed in a hot drink
A. Convection B. Conduction C. Radiation
This causes condensation on the outside of an ice cold drink

Typically, thunderstorms with large cumulonimbus clouds only occur in warmer months. That is because they are formed by….

Radio waves are an example of…

This causes plate tectonics (movement of plates on Earth’s surface)

Your cellphone creates/receives this to communicate to other devices

This causes trade winds, westerlies, and easterlies that affect major weather patterns. For example: The ITCZ near
the equator most often has clouds and rain. This is also where rainforests are.
