What is the name of the thick layer of ice and snow that has formed permanent crust over Alaska and antarctica?
Cheezpuff
The ocean waters freeze in winter. This is referred to as sea ice.
Ice in the form of glaciers being pushed out over the ocean is called an ice shelf.

The thick layer of ice and snow that forms a permanent crust over Alaska and Antarctica is called an ice sheet. Ice sheets are massive expanses of glacier ice that cover large areas of land.

Is a new oceanic crust formed at a transform fault boundary?
No. New oceanic crust is formed at a divergent boundary. A convergent boundary neither creates nor destroys crust.
What is the type of crust formed on the ocean floor?
Oceanic crust, formed mostly of mafic rocks, or sima, is found on the ocean floor.
Is the crust formed or destroyed at the sliding boundary?
At convergent boundaries are boundaries the crust is destroyed by subduction of oceanic crust underneath continental crust or other oceanic crust.
Is the crust formed or destroyed at a sliding boundary?
At convergent boundaries are boundaries the crust is destroyed by subduction of oceanic crust underneath continental crust or other oceanic crust.
Which feature is commonly formed at a plate boundary where oceanic crust converges with continental crust?
A deep ocean trench is commonly formed at a plate boundary where oceanic crust converges with continental crust. The oceanic crust is denser and is forced beneath the lighter continental crust, creating a deep trench.
Where new crust is formed?
New crust is formed at a divergent boundary
When is crust neither formed or destroyed?
Crust is neither formed nor destroyed when the rate of crust formation at mid-ocean ridges equals the rate of crust destruction at subduction zones. This balance is known as isostasy and helps maintain the overall thickness of the Earth's crust.
What is formed through the uplift under the earths crust?
crust
How the Alaskan range formed?
The Alaska Range was formed by the collision of tectonic plates along the boundary between the Pacific Plate and the North American Plate. This collision led to the uplift and folding of the Earth's crust, creating the rugged mountains that make up the Alaska Range. The range continues to be shaped by ongoing tectonic forces, erosion, and glaciation.
Is a new oceanic crust formed at a transform fault boundary?
No. New oceanic crust is formed at a divergent boundary. A convergent boundary neither creates nor destroys crust.
Ocean crust is formed were in the ocean?
Ocean crust is formed at seafloor spreading centers. One example of this is the Mid-Atlantic ridge.
What are forms of igneous rock?
Intrusive- Formed under the crust. Barley any Crystals. Extrusive- Formed out of the crust. More Crystals.
What is the type of crust formed on the ocean floor?
Oceanic crust, formed mostly of mafic rocks, or sima, is found on the ocean floor.
Ocean crust is formed where in the ocean?
New ocean crust is formed at mid-ocean ridges where tectonic plates are diverging (spreading apart).
Is the crust formed or destroyed at a sliding boundary?
At convergent boundaries are boundaries the crust is destroyed by subduction of oceanic crust underneath continental crust or other oceanic crust.
Is the crust formed or destroyed at the sliding boundary?
At convergent boundaries are boundaries the crust is destroyed by subduction of oceanic crust underneath continental crust or other oceanic crust.
In what era was the earth's crust formed?
precambrian
