Research Questions
Thermal Transfer
1. What is Earth’s source of thermal energy?
The Sun
2. List the three ways heat is transferred from one object to another. Explain each.
A: Conduction. When heat spreads from direct contact, like cooking a steak.
B: Convection. When heat moves through liquid movement, like the ocean currents.
C: Radiation. When electro-magnetic energy moves through empty space, like the Sun to our earth.
3. Which method of heat transfer occurs when the Sun’s energy is passed to Earth?
Radiation.

Formation of Wind
1. What type of energy transfer occurs to produce sea breezes?
Convection.
2. How are winds formed?
When one place has a lower air pressure than somewhere else, the air moves there
3. Where does the energy for the wind come from?
The Sun
4. What are the winds that form along the equator?
Hot wind***

Ocean Currents
1. What powers the ocean currents?
The Sun
2. What is the importance of ocean currents?
They help with annual migrations, they keep the ocean temperature the same, they
3. How are ocean currents formed?
Salinity
