Describe the processes of abrasion and plucking and how they result in the formation of a glacial horns.

Glaciers cause erosion in two main ways: plucking and abrasion. Plucking is the process by which rocks and other sediments are picked up by a glacier. They freeze to the bottom of the glacier and are carried away by the flowing ice. Abrasion is the process in which a glacier scrapes underlying rock.

They are like other investigations? say there was a murder u have to do blood test and finger prints which run through a lab.
