Outline the steps in taking a ridge count from a fingerprint

The steps in taking a ridge count from a fingerprint are as follows:

1. Draw an imaginary line from the center of the core to the edge of the delta

2. Count all the ridges that touch or cross the imaginary line

3. The core and delta should not be included in the counting

4. Incipient ridges are never to be counted regardless of where they appear

NUMERICAL VALUE ASSIGNED TO RIDGES

An island ridge – One count

A short ridge – One count

A long ridge – One count

Abrupt ending ridge – One count

A ridge that bifurcates across the imaginary line – Two counts

A bifurcating ridge whose point of origin is on the line of count – Two counts

Eyelet ridge – Two counts

Intersection of two enclosures – Two counts

The core is located on ending ridge which touches the inside of the innermost recurving – Four counts

glacial erosion, the picking up and movement of earth beneath a glacier, is also referred to as plucking. erosion and transportation of individual pieces of bedrock, especially large "joint block occur as a result of this glacial erosion. plucking is type of erosion in which rocks become frozen into the bottom and sides of the glacier.as the glacier moves downhill it 'plucks' the rocks frozen into the glacier from the ground.
