Which is true for all renewable energy resources? a. They are continuously replenished by natural processes.
b. They all formed deep within the earth over millions of years.
c. They can be used in their extracted form without further refinement.
d. They are made of recycled manufactured products.

Answers

The answer is a. They are continuously replenished by natural processes.

Renewable energy resources can be defined as resources that are continuously replenished by natural processes. These resources are sunlight, rain, geothermal heat, wind, tides, and waves. They should be distinguished from non-renewable energy resources which could not be replenished by natural processes, such as natural gas, fossil fuels, coal, etc. They could not be regenerated unlike sunlight or wind for example.

The answer that is true for all renewable energy sources is that A) they are continuously replenished by natural processes.

A scientific argument will be considered invalid if the evidence supporting that argument is based ona. inconsistent data.
b. independent data.
c. unlimited results.
d. controlled results.

Answers

I believe the answer to this is (B) independent data. Independent data can be obtained in an uncontrolled environment and can also be biased. Scientists depend upon each other to test each others data and results, but this isn't always the case with independent data and therefor the credibility is reduced.

The reason the other answers are incorrect is that unlimited and controlled results do not affect the validity of research, and inconsistent data means just that....that it is inconsistent and most likely requires more research or testing, but isn't necessarily wrong or invalid.
