Ice building up over the years.
Land bridges aren't actually formed, they are already there but covered by the sea. When a glacial period starts, the water evaporated from the oceans falls as snow on the land and then compacts as ice which does not melt. Continual removal of water from the oceans over thousands of years causes sea level to drop and exposes the "land bridges".
aboriginols got to australia over ice bridges and then the ice bridges meleted and they could not get back
Ice formed it.
the ice age formed by collecting ice together
Ice froze and they were formed...
Because the ice starts to form under it and on top of it. It's easier for bridges to form ice than roads which only get ice on the top and usually the road on bridges are thinner than regular roads.
Yes, the ice age played a significant role in creating land bridges. During periods of glaciation, huge amounts of water were trapped in ice sheets, causing a drop in sea levels. As a result, land bridges formed, connecting previously isolated areas, such as the Bering Land Bridge between Asia and North America. These land bridges allowed the migration of plants, animals, and even early human populations between continents.
it was formed by ice!
Shrinking of the polar ice caps Recession of glaciers and ice caps
They were already formed but the were covered with water.
The planets formed by ice would be Jupiter and Saturn!!......I think.............;)
Sometimes, due to the road mixture used, bridges can be icy while the rest of the road is not.
