Ninety-five percent of igneous rocks and metamorphic rocks are below
Earth's surface. Why is this true?

This is so cause ...

Igneous rocks are formed when the  molten material cools and hardens

and

Metamorphic rocks  form when they are subjected to high temperatures and the great pressure of the rock layers above it.

So most of these rocks are found beneath the earth''s crust

(I hope im right... this might not be the perfect answer... but this as close as I can get.. I hope it usefull  for u )

there all right good

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
