Answer:
2000 Kilometers.
Explanation:
We multiply how much the plate moves per year (10cm) by how many years the plate has been moving.
10 × 20000000 = 200000000
Then we convert the centimeters to kilometers
200000000 ÷ 100000 = 2000

Answer:
The great varieties of minerals on the Earth are classified by mineralogists into a small number of groups on the basis of : The negative ion or ionic group in their chemical composition.
Explanation:
Minerals are classified based on their chemical properties. The anion, a negatively charged ion that generally comes at the end of a mineral's chemical formula, is the fundamental foundation for classifying minerals, with the exception of the native element class. Cations are ions with a net positive charge because they have fewer electrons than protons. Anions, on the other hand, have a net negative charge because they contain more electrons than protons.
