What is a rake in geography?

In structural geology, rake (or pitch) is formally defined as “the angle between a line [or a feature] and the strike line of the plane in which it is found”, measured on the plane. The three-dimensional orientation of a line can be described with just a plunge and trend.

What is the difference between pitch and rake?

rake is more confortable for computer programs, while pitch is easilly measured in the field. They are synonymous. In structural geology “pitch” is the new term for “rake”. Rake (r) is the clockwise angle of the slip vectors from the azimuth of the fault plane and it is measured on a fault plane.

What are outcrops in geology?

Rock outcrops are defined as visible exposures of bedrock or other geologic formations at the surface of the Earth.

What are Foldings?

In structural geology, a fold is a stack of originally planar surfaces, such as sedimentary strata, that are bent or curved during permanent deformation. Folds in rocks vary in size from microscopic crinkles to mountain-sized folds.

How many is a rake?

Rake is the scaled commission fee taken by a cardroom operating a poker game. It is generally 2.5% to 10% of the pot in each poker hand, up to a predetermined maximum amount.

What is pitch and plunge?

Plunge is the vertical angle between the horizontal plane and the axis or line of maximum elongation of a feature. Plunge is measured along the axis of a fold, whereas dip is measured along the limbs. Pitch is the angle between the axis of the…

What is a rock outcrop called?

An outcrop is the exposed rock, so named because the exposed rock “crops out.” Outcrops provide opportunities for field geologists to sample the local geology—photograph it, hold, touch, climb, hammer, map, sniff, lick, chew, and carry it home.

How is an outcrop formed?

When weathering and erosion expose part of a rock layer or formation, an outcrop appears.

What is a monocline in geology?

A monocline (or, rarely, a monoform) is a step-like fold in rock strata consisting of a zone of steeper dip within an otherwise horizontal or gently-dipping sequence.

What are the functions of a rake?

A rake is a type of gardening or landscaping tool with a handle that ends in a head. You can use a rake for scooping, scraping, gathering, or leveling materials, such as soil, mulch, or leaves. Some rakes have flat heads; others have sharp metal tines that can break up compacted soil or rocks.
