Are you more likely to see sedimentary rocks on the surface or deep in earth's crust?
Of all the rock on Earth's surface, 75% is sedimentary rock. But, sedimentary rock is only about 5% of the whole crust. Unlike igneous rock, which forms underground, sedimentary rock forms from materials at Earth's surface. Which this means that sedimentary rocks are more likely to be seen on the surface. Hope this helps :)
