How do we help lessen our ecological footprint?

3. 1.What is Solar Energy?
(06:36)

4. ENERGY FROM THE SUN
Every human, plant, and animal depends on water for survival. It's controlled by the sun, which produces energy in the form of heat. This heat energy causes the water in the world's oceans, lakes, and even puddles in your backyard to warm and evaporate.
The Water Cycle is powered by the Sun.

5. What are the major disadvantages of solar energy?
The amount of sunlight that arrives at the earth's surface is not constant. It depends on location, time of day, time of year, and weather conditions.
Because the sun doesn't deliver that much energy to any one place at any one time, a large surface area is required to collect the energy at a useful rate.

6. renewable and nonrenewable.
We use many different energy sources to do work for us. Energy sources are classified into two groups—
renewable and nonrenewable.

7. Sources of Energy sun oil wind nuclear geothermal wind biomass water
Natural gas

8. 2. Identify the different renewable sources of energy

9. 3. Identify the different non -renewable sources of energy

10. 4.What are fossil fuels?

Answer key

29. 14. How is renewable energy better than non renewable energy?
Renewable energy is finite and cannot be regenerated easily.
Renewable energy can be replenished by nature in a short amount of time
Renewable energy is non-existent in nature.
Renewable energy is always available and cannot be ruined.

30. 15. How is non-renewable energy better than renewable energy?
Non-Renewable energy is finite and cannot be regenerated easily.
Non-Renewable energy can be replenished by nature in a short amount of time
Non-Renewable energy is convenient and readily available.
Non-Renewable energy is reusable and it does not run out.

31. 16. Which one of the following statements best describes the "Greenhouse Effect"?
The heating of the Earth by the Sun
The process where heat from the sun is trapped in the Earth's atmosphere.
The reflection of ultraviolet light, by the ozone layer in Earth's atmosphere.
The process that causes every plant on Earth to grow.

32. 17.Electrical energy can be produced from
mechanical energy
chemical energy
radiant energy
all of the above

33. 18. Which uses the most energy in American homes each year?

35. they are burned to release energy and they cause air pollution
20. Coal, petroleum, natural gas, and propane are fossil fuels. They are called fossil fuels because:
they are burned to release energy and they cause air pollution
they were formed from the buried remains of plants and tiny animals that lived hundred of millions of years ago
they are nonrenewable and will run out
they are mixed with fossils to provide energy

are clean and free to use
can be converted directly into heat and electricity
can be replenished by nature in a short period of time
