Mountains are large landforms that rise above the surrounding land, usually in the form of a peak. A mountain is generally steeper than a hill and is formed through tectonic forces.

glaciers are slowly moving masses or rivers of ice formed by the accumulation and compaction of snow on mountains or near the poles.

Volcanoes are mountains or hills that, have a crater or vent through which lava, rock fragments, hot vapor, and gas are being, or have been, erupted from the earth's crust.

Canyons are deep valleys with steep sides, often with a stream flowing through it.
