outcrop -- Any place where bedrock is visible on the surface of the Earth.
paleosol -- Soil horizon from the geologic past.

An exposure of bedrock. Outcrops can be formed naturally or by human action. Stream erosion and highway construction can produce outcrops.
A location where water is discharged.

Outcrop Area of exposed bedrock at the Earth's surface with no overlying deposits of soil or regolith. Outer Core Outer region of the Earth's core.

First, DEM data are combined with geologic maps to provide a series of points defining the outcropping surfaces of individual geological formations.

Always use bedrock when a suitable outcrop exists. Use a star drill to make a hole about 2.5 centimeters wide and 6 centimeters deep to receive the shank of the marker.

The geological time scale is generally constructed of periods named after particular places with specific outcrops. The first geological period of the Paleozoic era, the Cambrian, is named after the Latin name of Wales (Cambria).

" For example, certain land cover types such as grasslands are much better for pipeline location than dense forests. Similarly, gentle slopes are preferred over steeper ones and loose soils preferred over extremely rocky outcrop areas.
