What do glaciers leave behind as evidence of their existence?

1) Glaciers carve fjords in valleys where they travel. A fjord is a long, narrow valley with steep sides carved by glacial movement. A fjord represents the seaward end of a deeply excavated glacial-trough valley that was partially submerged by drowning after melting of the ice. 2) Glaciers leave behind deposits known as glacial till, which are unstratified, poorly-sorted sediments. Glaciers move a wide range of sedimentary particles from small clay-sized particles to large boulders. When the glacier either melts or retreats, these poorly-sorted sediments are deposited. These deposits are known as tillite in lithified sedimentary rocks. 3) A mound or ridge of till (unstratified glacial drift) is deposited when a glacier begins to retreat or melt. As the glacier grows and extends, it pushes glacial drift at its front forming a mound of debris. This glacial drift is then dropped in place when the glacier retreats or melts which creates a terminal moraine. Medial moraines, which are formed by the conjunction of two glaciers, are also deposited as a glacial melts. Glaciers erode the sides of the valleys in which they travel. Therefore, when two glaciers unite (in much the same rivers unite), a line of glacial drift (medial moraines) from both glaciers is formed. 4) Glaciers leave scrape marks behind on the rocks on which they traveled.


How does glacier erosion occur?

Glaciers can cause erosion because they move, though they do so slowly. As they move, often only a few inches a year, they scrape away and can gouge out the land, and then leave behind morass, which can be made up of left behind bits of rock or whatever happened to be in the glacier.


How are salts deposit formed?

High tides flood the salt pans with sea water which evaporates to leave behind salt deposits. This is how salt deposits are formed.
