(A) What are the two parts of the crust?
What is the basis of classification?

Answer 1

Answer:

Earth's crust is divided into two types: oceanic crust and continental crust. The transition zone between these two types of crust is sometimes called the Conrad discontinuity. Silicates (mostly compounds made of silicon and oxygen) are the most abundant rocks and minerals in both oceanic and continental crust.

Basis of Classification. Species is the basic unit of classification. Organisms that share many features in common and can breed with each other and produce fertile offspring are members of the same species. Related species are grouped into a genus
