Answer:
all of them except the wood
Explanation:
the solar panels, recycled copper plates, and recycled aluminum cups. are all "renewable," solar panels derive power from the sun, a renewable source of energy. the recycled copper plates have it in there name they are recycled, they will be used for a period and then melted down to make more plates or to be used in something else e.g wires. the cups are made from the alloy allumium which in its self is usually recycled but is just like the coper after they are used as the cups they can simply just be melted down to make anything else with the aluminum. wood is not a renewable source because you use it once and it's done.
I am almost positive that the answer is A. freezing
Answer:
Quartz is not pure in this rock.
Explanation:
When quartz shows effervescence in contact with an acid, it means that it is not in its pure state, but rather related to other substances that may be cementing the quartz. This effectiveness is caused by substances that do not react like quartz, such as calcite.
In this case, we can conclude that in relation to the calcium-rich rock shown in the question above, the calcium is not pure, but it is likely to be related to calcite, or other material that does not react to acid.
Answer:
Unconformities Are Gaps in the Geological Record
Gaps in the geological record, like those discovered in 2005, are called unconformities because they do not conform to typical geological expectations.Explanation:
The continental crust is made up of rocks that consist primarily of silica and alumina called the "sial". The next layer of the Earth is called the mantle.
