For the Love of Geography: Moraine

Moraine is a glacial landforms which results from glacial movement. As a glacier moves down the mountain it leaves behind debris of dirt and boulders.

Look below the glaciers in these photos. It looks like a river of rock. This is the debris left from the glaciers above which have retreated for the summer months.

For the Love of Geography: Arêtes

We continue our study on mountain glacial landforms with the arête.

An arête is formed by two glaciers scouring away rock on two sides of a mountain. The result is a thin ridge of rock which separates two U-Shaped valleys. Weathering further erodes the rock thus shaping and sharpening the feature. Arêtes can also be formed when two cirques erode.
