A geologist might use a piece of tile to identify a mineral because the unglazed surface of the tile can serve as an effective tool for performing a streak test. This test involves rubbing the mineral across the tile to observe the color of the streak it leaves behind, which can be a key characteristic for mineral identification. The streak color can differ from the mineral's appearance, providing additional information for accurate classification. This simple method is practical and widely used in fieldwork and laboratory settings.

A person who studies rocks, minerals, and earth's landforms is called a geologist. Geologists examine the composition, structure, and processes of the Earth's surface to better understand its history and natural resources.
A geologist would not consider a manufactured diamond, or synthetic diamond, to be a mineral in the traditional sense. While both natural and manufactured diamonds share the same chemical composition (carbon) and crystal structure, minerals are typically defined as naturally occurring substances. Since manufactured diamonds are created through human processes, they do not meet the criteria of being naturally formed and therefore are classified separately from natural minerals.
You would divide them into how the rocks were formed.Pumice, granite and basalt are all made from molten material that has since cooled. These rocks are calledigneous rocksthe other two are made up ofbits and piecesof other rock that have been cemented together. These are called clastic sedimentary rock.
Rocks
Yes, a geologist would study the composition of a mineral as part of their analysis of rocks and minerals in the Earth's crust. Understanding the chemical and physical properties of minerals helps geologists identify different rock types and formations, as well as the processes that formed them.
It would depend on their field of endeavor. See the related question.

Hydrochloric acid reacts with carbonate containing minerals (such as limestone) to release carbon dioxide (makes it fizz). By hand lens, I am assuming that you mean a magnifying glass. This would be important to view the details of the crystalline form of various rocks and minerals (I am not a geologist, though, so I am guessing here).
Many igneous rocks can be identified by the position of their minerals.
To obtain a minerals streak you would get a piece of the mineral and rub it against something that is strong enough to erode a little of it.
If you rubbed a piece of fluorite against a piece of feldspar, neither mineral would really change. Both minerals are relatively hard and have different chemical compositions, so they would not interact in a way that would result in a noticeable reaction.
A common task for a geologist in the oil field is to identify tailings for certain fossils and debris that would indicate promising oil and gas deposits. Also, when an archaeologist finds some artifact and wants to date it the geologist can identify other rock related formations to put a time line on it.
The science involved in diamond mining is geology: a geologist would identify the indicator minerals in a volcanic pipe that could signal the presence of diamonds.
