Igneous rock derives it's name from the Latin word ignis which means fire. It is formed when the magma after volcanic eruption gets cool and solidified either on the surface of earth crust or inside the earth crust. These rocks are characterized by their hardness. These rocks undergoes no chemical weathering but exhibit very low mechanical or physical weathering may occur. Therefore, hardness is the property which can be used to identify the origin of an igneous rock.

The first and the last question are the most relevant to the graph it’s self. The first question talks about the numbers dropping which would help clarify. The last one would help clarify what is producing these numbers. The second and fourth one are irrelevant to the graph. The third would also not be correct just because we don’t have enough information. I hope that helps!
Canda and Us are the most diversely populated countries in the world because they where founded by colonist. Colonist came from Europe and brought slave from all over. For example they brought slaves from Africa, India, The Americas, etc. Through out the years slavery was abolished so the free people had there own families causing diversity. Also, America and Canada are highly developed countries and many people from undeveloped countries migrate to Canada and America.
