underwater mountain ranges are very common. (apex)

ask and answer questions
how old they are how long the layers formed what kind of rocks
The answer to this question depends on what it is that the scientists are investigating. If, for example, they are investigating sub-atomic particles (eg Higgs Boson at CERN), the tracking different parts of the ecosystem will be of little use.
we use soil data to answer a very wide range of questions - from the obvious ones such as "which crops grow best where?" to more specific ones, such as "if we put this type of pesticide on this field, where will it end up? The river, the aquifer, or will it degrade in the soil?"
Often they will be, but similarly worded questions have been answered in the past.
Scientists use multiple trails in their investigation to find/confirm their answers
investigation
Because science is fueled by questions. The point at which scientists stop asking questions is when science becomes a theology.
Who, what, when, where, and why?
Scientific investigation is a systematic method in which scientists and researchers answers particular questions about the world around us. It consists of the following: an observation, a question or a problem, hypothesis, an experiment and a conclusion.
some of the questions scientists have about Mercury come from the limited knowledge we already have
All scientists ask questions, and test data
Investigation
Answer questions about the natural world :)
Thorough investigation
To answer the questions, Who - What - When - Where - and How. It is not necessary to determine "why" because if a crime was committed it is immaterial to the investigation to determine the reason.
That process is typically referred to as conducting an interview. It involves asking targeted questions to gather information from a person or group of people in order to further an investigation or research.
