Please answer as detailed as possible. Thank you!

The Earth's crust is the layer of rock which encases the mantle. However, all creatures live on the Earth's surface, which is cointained within the Biosphere- a combination of all the ecosystems on Earth.

Defintion of Biosphere:
The dirt that gets in the way of looking at the interesting rocks...

Oh no, there is a difference! I like stones, especially the round kind which go well in my soup

But soggy stones don't really count as stones, do they? (I guess they do if they are made by someone who really can't cook.)

It depends whether you are talking about oceanic crust, which primarily consists of the plutonic rock, gabbro and its volcanic counterpart, basalt or continental crust which consists mostly of less dense felsic rock, high in silicate, aluminum and sodium content. The upper mantle primarily consists of the much denser and molten ultramafic rocks which are much higher in magnesium and iron content than the two types of continental crusts and obviously much higher in temperature.

Not exactly sure what you're asking in your question. I will say this. Most of the Earth's surface due to weathering and erosion is covered by sediments and sedimentary rock. You do have the occasional exposed batholith made of granite here and there, various kinds of intrusive and extrusive igneous rock and exposed metamorphic rock, but primarily the surface is made up of mostly sedimentary rock.
