Glacial erratics aren't exactly formed. They were deposited by glaciers that were moving in that area at one time.
improved= Glacial erratics are exactly formed. Because a glacier is so heavy, the glacier can pluck large rocks as the glacier moves. When the rock is too heavy for the glacier to hold, or the glacier is retreating, it then deposits the rock in a place where it wouldn't usually be found. This is what an erratic is. A large piece of rock in an unusual surrounding.
i hope this helps :)

∙ 13y agoErratics are rocks of different sizes that are not the same from the glacial bedrock. This is usually mistaken with moraines which are glacial deposits, unsorted and unlayered pile of rocks, of erratics. Glaciers also leave behind striations which helps scientists determine and identify glacial activity.

∙ 12y agoAn erratic rock could be formed in any number of ways and could be of any type of rock. An erratic is simply a non-native rock; one that was transported and deposited, usually by moving ice, in an area where that type of bedrock is not found.

Are there glacial erratics or boulders in Georgia?
Yes. Between Gray and Monticello, 50 meters east of highway 11. Locals call it "The Rock".
What is an erratic?
An erratic is a rock fragment that was carried by glaciers and deposited some distance from its source. Erratics are generally found sitting on top of rocks of different age and lithology.
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 it called when glaciers pick up large rocks and carry them away?
It could be two things, either plucking, a form of glacial erosion where weak rock is moved or erratics, which is a form of glacial deposition in which rocks, even car size, are transported by glacial ice into a region with different bedrock.
Which is a landscape feature created by glacial deposits?
horns, cirques, Ushaped valleys, and glacial lakes. Glacial erratics if your doing it for
When was Glacial Erratics discovered?

What is the term used when a rock is found not in its natural place?
Rocks that have been transported from their place of formation are known as erratics (these commonly occur in areas where glaciation has occurred and so are known as glacial erratics).

What do scientists call the BOULDERS that are left behind when a glaciermelts?
They are called glacial erratics if they are different from the local surrounding rocks.
What are large deposits of boulders called?
The debris of boulders eroded and carried down by glaciers will eventually form moraines (mounds) where the front of the glacier melts and retreats, leaving the debris behind. Moraines can be high and wide enough to form a dam, behind which glacial melt water is trapped and lakes are formed.
