Question

why it why is it said that the minerals are not distributed evenly over the Earth

Answer 1

the distribution of minerals on earth is dependant on how and when they form . for example lot of heavy metallic minerals in the core of the earth and much lighter mineral in the crust . The distribution occurred in the planet was forming and so the dense thing slank and lighter thing float

Answer 2

good question!

the distribution of minerals on earth is dependent on how and when they form. for example, there is a lot of heavy metallic minerals in the core of the earth and much lighter minerals in the crust. This distribution occured as the planet was forming and so the dense things sank and the lighter things floated.

For minerals at the surface, you can find things like metals in very specific places and not spread throughout the crust. This is because metallic minerals often form as as part of a volcanic system (on land or under the ocean). The metallic minerals are deposited underground in theses systems and are only found when the volcano above is eroded away!

hope that helps!
