Continental ice sheets press down the Earth's crust.
They deposit rich soil over the land.
Glaciers carve valleys out of rock.
An example of isostasy is when the Earth's crust adjusts its elevation in response to changes in the distribution of mass, such as the melting of glaciers. As the glaciers melt, the weight on the crust decreases, causing the land to rebound and rise up in a process known as post-glacial rebound. This is a common phenomenon in areas that were covered by ice sheets during the last ice age.
crust
I believe this would be the oceanic crust
Another word for Earth's outer surface is "crust."
The average is 9 miles.The average continental crust thickness is 22 miles thick. The maximum crust thickness is 56 miles underneath the Himalayas, and is 16 miles thick at its thinnest in various places.The average oceanic crust is about 4 miles thick.For the entire Earth then, the average crust thickness is 9 miles.To scale size, the earths crust would be about the thickness of 3 ordinary sheets of paper on a basketball. The thickness of a chicken eggshell would be 16 pieces of paper on a basketball, so the earths crust is 5 times thinner than a typical egg shell. And the crust is only as thick as the egg shell at its maximum thickness underneath Nepal.Sleep tight.
"plates" are the term for the giant sheets of rock on the earths crust
Deformation
it means earthquakes will happen more often
Glaciers and ice sheets shape the Earth's crust through a process called glacial erosion, where their immense weight and movement carve out valleys, fjords, and other landforms. As glaciers advance, they grind rock and sediment beneath them, transporting materials and altering landscapes. When they melt, they can also contribute to isostatic rebound, where the crust rises in response to the removal of the ice's weight, further reshaping the terrain over time. These processes play a significant role in sculpting the Earth's surface and influencing geological formations.
after shock
Erosian, weathering.
It causes it to deform - this deformation is called "strain".
because when it acts on the surface it stretches the rock to make craters or " dents" on the crust.
glaciers didnt help in formation of earth crust! if you mean how DO they then i would say that they create valleys or craters with their weight and deposit fresh sediments while frozen and also when they melt.
The Earths crust is approximately 650 km deep.
Crustal subsidence can be caused by a variety of forces, including tectonic plate movement, sediment compaction, and the melting of ice sheets or glaciers. These forces can lead to the Earth's crust sinking or settling, resulting in subsidence.
Areas of the crust that were once covered by continental glaciers are likely still experiencing rebound, a process known as isostatic rebound. This is the slow uplift of land due to the removal of the weight of the ice sheets, causing the crust to rise.
