List the three ways heat can be transferred from one spot to another:
________________________________ ____________________________ _______________________________
Which form of heat transfer can occur through empty space? _____________________________
Which form of heat transfer occurs in liquids and gases? ___________________________
Which form of heat transfer occurs by direct conduct? ____________________________
Heat always moves from an area of ________________________ temperatures to _________________________ temperatures.
-Determine the type of heat transfer that is going on in the following situations.
Options: radiation, conduction, or convection
You burn your hand on a hot light bulb. _______________________________________
An air current allows heat to be transferred from the equator to the North Pole.
A cloud is formed when hot air rises and then cools. ______________________________
The sun’s energy reaches the surface of Mercury ________________________________
The air directly above the fire felt warm. _______________________________________
Copper was a better conductor than the other metals. ___________________________________________
Hot air rises, cold air sinks. ___________________________________________
The seat was very warm when I sat down in it. _________________________________
The ice melted as it was placed on the metal plate. _____________________________
Air in the atmosphere continuously moves. At the equator air rises and at the poles it sinks.
The main way liquids transfer heat is through ___________________________________.
The light bulb allowed my hands to get warm as I held them close. ____________________________________
-Earth Energy Budget:
Draw a picture which demonstrates how energy is absorbed or reflected. (Be sure to include %)
________ % is absorbed by the __________________ and land.
The _________________ reflects approximately 20-30%.
Explain why the earth’s surface is not heated evenly. (hint…2 reasons) a.
Why does the temperature of our planet remain in a constant balance?
-Factors of Weather: Temperature
What is the source of heat for Earth?
What happens to MOST of the heat radiated from the sun?
What happens to MOST of the sunlight that enters Earth’s atmosphere?
What does heat radiated from Earth’s surfaces do?
-Temperature Continued: Factors of Heating
Why is the air around the equator warmer than the air around the North or South Poles?
How do clouds prevent the Earth from becoming warmer during the daytime?
Why does warm air rise?
