"One of the critical differences between marble and granite is that marble is a sedimentary stone (made from sediments, i.e., small rocks, bones, etc.)

Granite is an igneous rock (formed by magma that cools down and solidifies over time).

Marble may be etched when exposed to acidic substances (lemon, orange, etc.) in building and decoration applications. It is because it contains calcium (from the bones, i.e. 'sediments').

On the other hand, because granite is not a sedimentary rock, it does not contain calcium (i.e. it does not etch when exposed to acidic substances).

And one of the main reasons why granite is more popular than marble in applications such as kitchen worktops.

Hop it this helps!"
