How Are Striations Formed?
When a Glacier moves over an area of soft or hard rock it may have smaller stones underneath it, these small stones scratch into the larger rock making the Striations. They show which direction the Glacier travelled in.
Why do glacial striations show the direction a glacier moved?
In the sense that it makes it known that the rock existed before a period of glaciation, yes.
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 are the scratches left behind from glaciers called?
striations
Which type of muscle doesn't have stripes?
The "stripes" in the muscle are called striations. Smooth muscle doesn't have the striations.

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.
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.

striations
Do cardiac muscles have striations?
Yes they have Cross Striations
What do striations muscles look like?
Striations are light and dark bands on skeletal and caridac muscle fibers. Smooth muscle lacks striations
Can you give a sentence for the word striations?
The marble was smokey grey with black and white striations.
What feature is the result of a glacier carving out rock as it moves?
The feature that is the result of a glacier carving out rock as it moves is a roche moutonnees. It is a rock formation created by the passage of glacier ice. Or a terminal moraine

The "stripes" in the muscle are called striations. Smooth muscle doesn't have the striations.
