Three characteristics that geologists use to identify a rock sample is color, hardness and streak. They can also check for other physical properties such as if there is a taste, if it is radioactive or if it gives off an odor.

So I didn't know that 3 was 4 because I see 4 characteristics not 3

geologists can study a rock sample by observing its composition, color, and texture. they also look at the rocks structure, hardness and weight.

Information on geologist?
What is a geologist? A geologist is a person who studies the Earth and the materials it's made up of (A.K.A. geology). Geologists are also the subject of this speech. There are many kinds of geologists like economic geologists and marine geologists are two examples but I'm just going to deal on the general geologist. A major science they use is Earth science. Earth Science is any of the basic geologic sciences that are connected with the source, arrangement, and physical phenomena of the earth. Using this science geologists can identify countless things. They also identify rocks & minerals. To help identify a mineral's hardness, geologists use Moh's Mineral Scale of Hardness. This scale lists 1-10 weakest to hardest minerals. Moh's Scale is very helpful to geologists. There is also a lot of math involved with geology. One of these is calculus. Calculus is analysis of numbers with special symbols. Calculus helps with making graphs, diagrams, 3-D and 2-D maps, etc. Plus, using calculus geologists can make mathematical models to find oil. Most geologists need to use calculus! SO CALCULUS IS VERY VERY important to Earth Science. Like I said before, geologists are very good at studying rocks. There are three types of rocks: Igneous which is formed by magma and/or lava, Sedimentary which is formed by tiny & big sediments and Metamorphic which is a rock changed by heat & pressure. An example of Igneous is Basalt, a sedimentary is shale and a metamorphic is quartzite. Guess who figured this out. GEOLOGISTS! If it weren't for geologists, we really wouldn't know what rocks were, are, and will be.
What are the three demographic variables?
The three demographic variables commonly used are age, gender, and income. These variables help categorize and identify characteristics of a population for research and marketing purposes.
