Answer:
the fossil organisms lived for only a short span of geologic time
Explanation:
The index fossils are very useful when it comes to determining the relative age of the rock layers, as well as the other fossils found in the same layer with them. These fossils have four basic characteristics, they appear only in limited geologic time, they are widespread, abundant, and distinctive. The fact that they are limited in their geologic existence is very good for the geologists as when they find a fossil like this they are immediately aware of the geologic period they are working with without having to make examinations. Also, these fossils can be found in abundance and in numerous places around the world, thus the same fossil can be used as a time scale almost everywhere. Being distinctive also helps a lot because the geologist can immediately be aware of the type of organism without having to further examine it.
Answer:
d) both B and C
Explanation:
Although it has been proven that non-renewable resources such as petroleum are indeed running out and are no infinite, many people believe that there are enough non-renewable resources left on the planet to not worry too much about investing all our resources in renewable energy. This reality will only change with a better education system.
It is also true that efficient technology does no always exist and that when it does can be quite expensive. A good example is the difficulty of storing excess solar or wind energy to be used when atmospheric conditions cause a drop in production.
