A geologist collects five different rock samples The geologist identifies the five samples as pumice granite basalt siltstone and sandstone If you were a geologist how would you divide the samp?

Answer 1

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 called

igneous rocks

the other two are made up of

bits and pieces

of other rock that have been cemented together. These are called clastic sedimentary rock.

Answer 2

I would likely divide the rock samples based on their mineral composition, texture, and formation process. Pumice is an igneous rock formed from volcanic activity, granite is also igneous but has larger mineral grains, basalt is fine-grained igneous rock, siltstone is a sedimentary rock made of fine particles, and sandstone is a sedimentary rock made of sand-sized particles. Grouping them this way would help identify their geological significance.
