Answer:
It is important to have more than one piece of evidence to make sure that the evidence is actually evidence. Or in other words, that the evidence is proven true. With only one piece of evidence, you can't be fully sure if calculations were correct, if the source was trustworthy, etc.
Multiple evidence is kinda like double checking math problems. If you don't do it, you can't be 100% certain the answer is correct.
Highly porous and permeable
Explanation:
Compared to other types of rock layers, an aquifer is highly porous and permeable.
Aquifers are always the target when prospecting for ground water in a formation.
- Porosity is the amount of void spaces in a rock.
- Aquifers are highly porous .
- Permeability is the inter-connectivity of the void spaces and their ability to transmit fluids.
- Aquifers have very high permeability compared to other rock types.
In terms of permeability and porosity, an aquifer is higher porous and permeable.

Answer:
All
Explanation:
You would need carbon dioxide to be able to sustain life forms such as plants, warm enough temperatures to allow the development of animals, (because they cannot be frozen), they would, of course, need oxygen to allow anyone to breathe, and finally liquid water to sustain healthy life, because we must hydrate that is necessary for survival.
