Heat Transfer
1. What is Earth’s source of thermal energy?
Earth's source of thermal energy is the sun.
2. List the three ways heat is transferred from one object to another. Explain each.
1. Radiation- the transfer of heat from one object to another through empty space in the form of electromagnetic energy.
2.Conduction- transfer of heat between two objects that are touching
3.Convection- the hot air or liquid rising and the cool air or liquid sinking.
3. Which method of heat transfer occurs when the Sun’s energy is passed to Earth?
Radiation occurs because the heat is traveling through empty space in the form of electromagnetic energy.
Formation of Wind
1. What type of energy transfer occurs to produce sea breezes?
Convection produces sea breeze.
2. How are winds formed?
The uneven heating of our earth causes wind.
3. Where does the energy for the wind come from?
The energy for the wind cones from the sun.
4. What are the winds that form along the equator?
The trade winds are the winds that form along the equator.
Ocean Currents
1. What powers the ocean currents?
Wind powers ocean currents, particularly surface currents.
2. What is the importance of ocean currents?
Currents are important for trading and moving in the ocean. They also transport heat and nutrients from one part of the ocean to another.
3. How are ocean currents formed?
The rotation of the earth, continental deflection, and salinity all cause currents. Wind also has an influence on currents.
