Did glaciers form mountains?
When glaciers began their final retreat 10,000 years ago, they left behind many landscape features, such as lakes, valleys, and mountains. Bowl-shaped cirques, where most alpine glaciers form, became mountain lakes. These alpine lakes are called tarns. Glaciers can also create lakes by leaving depressions in the earth.
Do glaciers cause valleys?
Glaciers carve a set of distinctive, steep-walled, flat-bottomed valleys. U-shaped valleys, fjords, and hanging valleys are examples of the kinds of valleys glaciers can erode.
How do glaciers help in the formation of mountains and valleys?
A glacier’s weight, combined with its gradual movement, can drastically reshape the landscape over hundreds or even thousands of years. The ice erodes the land surface and carries the broken rocks and soil debris far from their original places, resulting in some interesting glacial landforms.
How do glaciers affect valleys?
As they pass over the ground, the ice scrapes up soil and rock. A valley glacier will leave a valley much deeper, as it erodes the underlying surface with plucking and abrasion. Plucking occurs when large rocks or other objects are pulled out of the earth by the force of the glacier’s movement.
Do glaciers affect us?
Today, glaciers often are tourist attractions in mountainous areas. But glaciers are also a natural resource, and people all over the world use the meltwater that glaciers produce.

Why did the Britannic sink so fast?
It was such a hot day too that the portholes were open so people could cool down. As the ship sank lower in the water, water flooded through the open portholes, making the ship sink faster. The Britannic was also directed to sail towards land, which only helped flood the ship faster.
