Answer:
1.
A theory is why something happens and a law is how something happens.
Explanation:
Whenever scientists or people studying scientific disciplines face any scientific question, they try to solve it through proper scientific method. Two of the most important steps of scientific methods are to propose a theory as an answer of the question and after it formulate a law if it can be formed.
In simple terms we can think of a theory as an logical answer that why a certain phenomenon occurs. On the other hand a law is a statement that shows how a phenomenon occurs and it can help in predicting about the phenomenon. Laws are relatively general as compared to theory because theory is logical and well reasoned explanation about a certain happening.
A theory grows into a law when several group of people work on the same question and find same answer in such a way that it is universally approved. Theories can be revised after repeating experiment or condition however scientific law can never be proved wrong and it remains same.
For example: Darwin's theory called Neo- Darwinism in which he said that living organisms can be produced from non-living organism was disapproved by scientists after careful experimentation. It explained the reasoning that why living organisms can be produced from non-living organisms however if it had been proved by all scientists it would become a law which just explains that how living organisms are produced from non living in a general one or two lines statement. For example: Newton's law of motion.

There has been two eons in the Earth's geologic history so far, the Precambrian eon, and the Phanerozoic eon. The eons are the basic and by far longest units on the geological time scale, spreading over hundreds of millions of years.
The Precambrian eon is the eon that starts with the formation of the Earth, up until the development of multi-cellular organisms. A very important event in this eon can be considered the formation of the Earth's oceans, which later enabled the conditions for the development of life. The organisms that dominated this eon are the one cellular organisms.
The Phanerozoic is the eon in which the multi-cellular organisms started to develop and evolve. This eon started with the end of the Precambrian eon, 543 million years ago up until the present. A very important event in this eon is the change of the composition of the atmosphere, which enabled the terrestrial life, as well as the better living conditions for the marine life. It is very hard to choose a dominant form of life in this eon, but worthy of mentioning are the plants, the sinapsids, dinosaurs, mammals, fish.
Recycle and renew are the two R's that uses and transforms the waste material. Recyclables do not equate to renewable as recyclable materials do not occur naturally.
<h3>What are recyclable and renewable?</h3>
Recyclable is the resources that are used finite times over and over and undergo a certain process for re-use purposes. They can be naturally or by humans, processed to be used again.
Renewable is resources that are natural and are replenished in nature when gets decreased by natural processes.
Some recyclables like aluminum and glass are not renewable as they are not formed naturally and do not get replenished by natural processes.
Therefore, recyclables are not renewables.
