The blocky brown-gray rock with wide fractures (cracks) is an ancient lava flow (basalt. This outcrop is a natural geologic cross section of rock layers.

Assuming that the red sandstone layers were originally horizontal.
If you assume that the global amount of radiocarbon (formed by cosmic-ray bombardment of atoms in the upper atmosphere and then dissolved in rain and seawater) is constant, then decaying carbon-14 is continuously replaced in organisms while they are alive.

Then place arrows along the right edge of the mke that point to each contact.
Label each arrow (contact) to show its relative age from 1 (the time when the ﬁrst contact was created: the oldest contact) to “n" (the number corresponding to the last time a contact was created; the youngest contact). The picture below is an outcrop about 5 meters thick near Sedona, Arizona. The brown layer in which grass is rooted is modern soil.
