According to the passages we read, it is possible for a good man to have his steps order by the Lord while at the same time his foot slips and he falls. But the difference between a good man versus and evil one is that he never stays down. An evil man, on the hand, never repents. He continues the same course.
Abrasion is defined as the erosion that occurs when particles scrape against each other. The enormous weight of the glacier, along with rocks and sediment plucked up and clinging to its belly scratch and carve the rock surface below. It's almost as if the moving glacier is sanding the rocks with abrasive sandpaper.
Glaciers cause erosion in two main ways: plucking and abrasion. Both are illustrated at this link: [Insert a link to an animation showing how glaciers cause erosion by plucking and erosion.] 1  Plucking is the process by which rocks and other sediments are picked up by a glacier. 2  Abrasion is the process in which a glacier scrapes underlying rock.
