What kinds of observations did scientist use at first group organisms into a phlyum or class?

the basic characteristics scientists look into to group organisms are:-

1) CELL STRUCTURE: whether it's prokaryotic(without a nuclear membrane) or eukaryotic(with a nucleur membrane). Also, whether it's unicellular or multicellular.

2)MODE OF NUTRITION: Whether it's autotrophic(prepares it's own food), heterotrophic(depends on others for food) or saprophytic(depends on dead matter)

3)COMPLEXITY OF ORGANISATION: Where the animal is placed in the evolutionary cycle. the higher on the evo. cycle, the more complex the organism...

What scientists work in mining?

Mineralogists work in mining. Their object of study is called Mineralogy.

There are some classes of mineralogy. Chemical, biomineralogy, Optical,

/ Physical, which includes crystal structure, crystal habit, twinning, cleavage, luster, diaphaneity, color, streak, hardness, specific gravity. /

Chemical mineralogy focuses on the chemical composition of minerals in order to identify, classify and categorize them, as well as a mean to find beneficial uses from them.

Biomineralogy is a cross-over field between mineralogy, paleontology and biology.

Optical mineralogy is a specific focus of mineralogy that applies sources of light as a means to identify and classify minerals.

Why do scientists use models to represent earth?

Scientists use models to represent Earth because they allow them to simulate and study complex Earth systems in a simplified way.
