Heat Transfer
1. What is Earth’s source of thermal energy?
The sun is Earth's source of thermal energy, because it plays a part in everything on the earth. For example, plants use sunlight for photosynthesis, etc.
2. List the three ways heat is transferred from one object to another. Explain each.
1.Radiation: transfer by electromagnetic waves.
2.Conduction: transfer by molecular collisions.
3.Convection: transfer by the circulation of a fluid.
3. Which method of heat transfer occurs when the Sun’s energy is passed to Earth?
Radiant energy (radiation) is the method of heat transfer that occurs when the Sun's energy is passed to the Earth.
Formation of Wind
1. What type of energy transfer occurs to produce sea breezes?
The type of energy transfer that occurs to produce sea breezes, or wind is kinetic energy. Kinetic energy can be captured and converted to other types of energy like mechanical and electricity power.
2. How are winds formed?
Wind is formed when the sun heats the earths surface unevenly and the air near the ground becomes warmer and lighter. Then the warm air rises and cool air takes its place on the ground. Soon the cool air also becomes heated and then moves up into the atmosphere.
3. Where does the energy for the wind come from?
The energy for the wind comes from the sun. The suns energy rays hit the planet in vast areas. In some areas is very hot like the rain forest, and in some places the it is very cold like the Arctic. The hotter area's air is more heated the the colder area's air which leads to convection currents in the atmosphere, which moves the different types of air, which is now wind. The wind also has changes in its density and pressure as it moves along the planet.
4. What are the winds that form along the equator?
Air movements that move toward equator are called trade winds, which are warm, steady winds that flow continuously. The Coriolis effect makes the trade winds flow to the west, even if the winds originally came from the north and the south. The winds that form here are very hot winds and they are less dense than cold winds.
Ocean Currents
1. What powers the ocean currents?
Wind causes surface ocean currents. Different density and how much salt is in the water and convection and wind power and change deep ocean currents.
2. What is the importance of ocean currents?
Ocean currents control the temperature.
3. How are ocean currents formed?
Wind, solinity, and convection create ocean currents.
