Photo captions at the bottom of each image. 
These pics are rocks of the continental and oceanic rsuts and the mantle.

Sandstone in Zion National Park.  Sandstone is a
common rock of the upper part of the continental crust.
This one represents fossilized sand dunes, millions of
years old.

A slab of pinkish granite used as a countertop.  Granite
is also a common rock of the continental crust.

  A rock from the deep continental crust now exposed at the
Earth's surface, in Japan.  This rock has been cooked under
high pressures and temperatures.  The red spots are the mineral
garnet.

Oceanic crust at the bottom of the Pacific ocean.  Lava that pours
out onto the ocean floor often forms these blobs called "pillows".
Many are shaped like elephant trunks.

Ancient oceanic crust shoved up on land at Macquarie Island,
south of New Zealand.  Compare with the previous photo.

Oceanic crust (left, grayish) and mantle (center and right, brown) have
been shoved up onto land in Newfoundland, Canada.  The dark stripe
near the center between crust and mantle is the fossil Moho.  These
rocks are about 600 million years old.

Mantle rocks in Newfoundland showing typical "dun" color
of weathering.  These rocks are green on a fresh surface.
