What is the process in which a glacier loosens and moves rock?
The process by which a glacier loosens and moves rock is called glacial erosion. It occurs when the glacier's immense weight and movement cause it to pick up and carry rock fragments. As the glacier moves, these rocks scrape and grind against the underlying surface, gradually wearing it down and forming characteristic features like U-shaped valleys and striations on bedrock.
What is the process for the rocks dragged by glaciers produce grooves and scratches in bedrock?
striations
Abrasion and plucking involves what part of glacier?
The base of the glacier, where it is in contact with the rocks beneath it.
How does ice transport materials?
Through Plucking, when melt water freezes in the cracks of a mountain, and plucks out the loose rocks, and also abrasion, when the looses rocks scrape along the valley floor, to pick up even more till, and create striations, which are marks left on the valley floor. Ice also picks up even more rocks through landslides, or rocks falling over the hanging valley, (which is a steep drop created after interlocking spurs have been truncated, by the glacier cutting through them.) The rocks and other natural debris then is frozen, by the melt water, and is transported as the ice moves, in a glacial retreat, or advance.
What can happen when the glacier melts in a cirque?
the glacier dropped small rocks as it melted. An erratic is a large boulder left behind after a glacier has melted
What is a striations?
A striation is a big or small gauge on a rocks surface usually caused by glaciers sliding past the rock. This tells us in which direction the glacier was traveling.
What are glacial striations and glacial erratics?
Striations are "scratches" left in bedrock by glaciers. A small particle of rock, generally pebble sized or smaller, becomes entrained in the base of the glacier and dragged along the surface of the bedrock. These can often be seen on hard bedrock surfaces that are resistant to subsequent weathering after the retreat of the glacier. Erratics are large rocks that are found out of place in the landscape, i.e. not near where they were formed. They are removed from their provenance by a glacier and transported away, before being deposited in a different part or the landscape when the glacier melts.

Why would a smooth rock fall faster than a bungee jumper?
smooth rocks create less friction on air.
How can glaciers erode rocks?
The glacier can carry rocks. The moving of the glacier.
What are the scratch marks on rocks from moving glaciers called?
striations, striae
What is the process for the rocks dragged by glaciers produce grooves and scratches in bedrock?
striations
Where are striations?
On rocks - they are the parallel groves or scratches. Or on skeletal or cardiac muscle: they are the "strands" of the muscle.
Are the rocks in cape cod smooth?
why are most of rocks extremely smooth
Abrasion and plucking involves what part of glacier?
The base of the glacier, where it is in contact with the rocks beneath it.
What is a moving river of ice that carries rocks and wearys away the land called?
Glacier
