Question

What is meant by STRIKE, DIP and OUTCROP.

Answer 1

DIP is the acute angle that a rock surface makes with a
horizontal plane.
STRIKE is the direction of the line formed by the intersection of a rock surface with a horizontal plane.
OUTCROP is a large mass of rock that stands above the surface of the ground.

Answer 2

Dip, Strike and Outcrop.

Explanation:

• Dip-It refers to the angle of inclination of a rock bed with the horizontal plane .It is measured in plane perpendicular to the strike.

In addition, to the amount of dip,its direction must also be stated which is measured with a clinometer.

There are two types of dip:-

• True dip-Maximum angle of dip on a rock bed and is measured in the direction perpendicular to the strike.

• Apparent dip-A dip measured other than the true dip. It will always have a direction less than the true dip.

• Strike- It is the trend of the rock bed on the ground surface.It may be defined as the direction of a line formed by the intersection of a bedding plane and a horizontal plane.

• Outcrop-It refers to the exposure of the bed or the rock layers due to erosion.
