What does renewable energy mean? Provide two examples with your answer.
energy from natural resources that can be replenished at a higher rate than we use it
examples: solar, wind, geothermal, biomass
Large windmills spin turbines which generate electricity
Wind Energy
What does condensation mean?
When water vapour cools and turns into water droplets forming clouds
How does the Sun contribute to the Water Cycle
Provides energy so that water phase changes can occur.
What percent of the Earth's surface is covered by water?
70%
What does non-renewable energy mean? provide two examples with your answer
Non-renewable energy - a natural resource that cannot be replenished as quick as we use it
examples: nuclear, coal, gas,
Hydroelectric

What is an advantage and disadvantage of fossil fuels?
Advantage - cheap, easy to get
Disadvantage - produces pollutants, toxic to the environment

Does water leave and enter the water cycle at any given point? explain your answer.
No, water in the water cycle always stays the same, it just changes its form.
example: water evaporating out of the ocean and turning into a gas from a liquid
Label E
E - Runoff
If all the trees were cut down in a large area how would this affect the water cycle?
the water in the water cycle will still remain the same amount, there just won't be any transpiration from trees. Evaporation will have to occur from bodies of water within the area instead.
If a resource, such as trees, are cut down and used faster than they can re-grow, can they be called a renewable resource? Explain your answer.
No, it cannot be called a renewable resource. this is because we are using the material at a faster rate than we can replace it.
Heat from inside the earth
Geothermal
