What will rocks look like when glaciers or rivers have moved them?

Glaciation marks on stone, called striations, show the markings left by the movement of glaciers; this is usually directional and there will be scoring or scratch marks; parallel markings showing north-south movement. This can be seen clearly on mountaintops in the Catskills, on some rock outcroppings in Central Park in New York City, and throughout the Northern Appalachian chain. Individual stones may or may not show evidence of glaciation.
Rocks found on site in combination with fine gravel and powdery material are indications of a glacial moraine; moraines are formed by the deposit of materials left after glaciers retreat. Individual stones may also exhibit glacial polish from friction with fine-grained rock particles suspended within the glacier.
River rocks are usually well rounded by erosion caused by the scouring of fine particles carried by the river.

Glacier ice covering a highland area?
Glaciers flow, like rivers, except they flow much more slowly. Like rivers, glaciers can carry sediment, stones, rocks, and boulders downhill. When large rocks are found downhill from the original rock formations, for example, in mountains, one can propose that the glacial ice fractured the boulders from the mountain, and carried them to their -- often far away -- final resting place. Geologists can match the type of stone found downhill and the stone in the mountain from which it was moved by the glacier. This can confirm that the geography in between was covered at some point by a glacier.
As glaciers move the rocks and boulders frozen in them work like?
sandpaper
What will happen in the future of glaciers?
If global warming continues, then glaciers, which are like rivers of ice, will continue to melt and finally disappear. Many of the world's great rivers get water from the spring melting of glaciers, so if glaciers vanish, the rivers and the people who rely on them, will be threatened.
What are glaciers like?
Glaciers are big ice forms that form in really cold waters. They are like land except in ice form.
How a bulldozer is not a accurate model of how glaciers cause rocks to move in grooves in rocks and other formations on the surface of the earth?
A bulldozer simply pushes loose material in front of it. A glacier is a continuously-fed, rasp-like structure that will push debris in front of it, but its main action is from ice-plucking and abrasion by rocks trapped in the ice in its base.

What is it like in the Himalayas?
The climate near the Himalayas is extremely harsh, ranging from humid to icy. There are glaciers, rivers, forests, and jungles.
Why are rivers bendy?
'cause things get in the way. like rocks and twigs and stuff.
What part of the earth has water in it?
the wet parts like oceans, seas, lakes, rivers, creeks, glaciers, clouds, moisture in the air, etc.
What are the names of all the names of the rivers in England?
Justin bieber rocks and whoever does not like him their stupid idots
What are the rivers of ice found in antarctica called?
Ice that flows like a river is called a moving glacier, at least that's the name of this phenomenon given by the National Science Foundation (USA) to Upstream Bravo in Marie Byrd Land in Antarctica.
Why you should study glaciers?
Glaciers may seem like an unimportant, uninteresting topic, but it has made significant changes to the landscape in nearly every area of the world. Even what are today very warm areas, glaciers could have existed millions of years ago. Results of glaciers include "U" shaped valleys with the edges scratched/polished by the things the glaciers carries. Glaciers also have incredible moving strength. Boulders have been known to be moved hundreds of miles from their original position.
Where erosion usually happen?
Everywhere water is frequenly in contact with rocks. Like seashores, rivers, underground caves etc...
What are earths waters like?
If you are talking about natural waters, they are either salty (ocean --> covers most of the world; 97%) or fresh (lakes/rivers/glaciers --> not so much; about 3%)
How did the glaciers help form the geography in the Midwest?
Glaciers shaped the geography of the Midwest by carving out the Great Lakes, depositing glacial debris that formed the fertile soils of the region, and creating other landforms like moraines, drumlins, and kettles. The retreat of glaciers also left behind numerous lakes and rivers that support the agricultural and transportation networks in the region.
