Polar
Subarctic.
they are on oceanic lithosphere.
The dominant type of rock in Arctic lowlands is generally sedimentary rock, such as sandstone, siltstone, and shale. These rocks are often deposited by glaciers and rivers and can be found in the flat and low-lying areas of the Arctic region.

The lithosphere is the solid, outer part of a planet. All terrestrial planets have lithospheres, but the lithospheres found on Mercury, Venus, and Mars, are thicker and more rigid than Earth's. Mercury's lithosphere lacks fluids and is thick and immobile. It has not changed much in the last billion years.
The polar bear is found in the Arctic Circle and the nearby islands. They can be found in good numbers in Alaska, Norway, Denmark, Russia and Canada. There are smaller populations in the surrounding regions near the Arctic pole. They prefer the Cold Icy areas of the Arctic and thrive in areas where the human intervention is minimal. They are found in good numbers in areas where their primary prey, the Seals mate and nest.
From Runescape Wikia: "The Cavefish are a type of fish that can only be found in the Living Rock Caverns. The Living Rock Caverns can be found underneath the Dwarven Mine..."
Arctic foxes live in dens.
Ice-breaking ships are used in the Arctic using wedges, a type of simple machine.
At a convergent boundary, two lithospheric plates are colliding. This collision can involve oceanic lithosphere converging with either oceanic or continental lithosphere, or continental lithosphere converging with continental lithosphere. The type of lithosphere involved in the collision influences the resulting geological features, such as subduction zones or mountain ranges.
Reverse faulting is commonly found where two slabs of continental lithosphere are converging. The compression forces cause the rocks to deform and create reverse faults, with the hanging wall moving up relative to the footwall. This type of faulting is associated with convergent plate boundaries and mountain-building processes.
