What are the rounded basins carved into the sides of mountains by valley glaciers?
they are called Corries or cirques!
How do glacier horn form on a mountain?
Ussually by three cirques A cirque is an origin point for glaciers in mountainous areas. It is a deep depression with three high walls and an open area from which the glacier moves forward, down the mountain side. Over time, as rock is eroded, these become wider and deeper. A mountain horn, such as the Matterhorn in the Alps forms when a peak is surrounded on two or more sides by cirques. As the cirques expand and rock is eroded the peak is honed into a point, forming a horn.
What is a feature formed by tributary glacier?
I know three: morains (a hill of dirt and rocks where the glacier stopped moving and then melted), carved valleys that are U-shaped vs. those valleys cut by a stream or river, rocks that are very smooth because of the ice and rocks they slid over.
Are continental glaciers larger than valley glaciers?
Yes. A continental glacier spreads around all sides, while the valley glaciers spread along it's length.
Which glacial feature has steep cliffs?
Some were, if in the mountains. Glaciers carve out deep U-section valleys with very steep sides and headwalls. Coastal cliffs though are formed by the sea eroding the land, and the nature of the cliff depends very much on the rock in which it is being cut.

What can create cirques on the sides of mountains?
A cirque is the top of a glacier valley.

When 2 cirques on opposite sides of a valley meet what do they form?
Moraine
Does glaciers always melt from the sides first?
Not always but

Why do young fold mountains have rounded peaks?
Eventually, natural weathering (over an extremely long time) will wear the rounded peaks into sharper edges. Most extreme weathering occurred during the ice-ages. Glaciers scoured out 'U' shaped valleys, shaved the sides of the mountains, sharpening the mountains into their present shapes.
Are continental glaciers larger than valley glaciers?
Yes. A continental glacier spreads around all sides, while the valley glaciers spread along it's length.
What do the presence of waterfalls on sides of mountains reveal?
Waterfalls on the sides of mountains reveal much about hydrology.
In California most precipitation falls on the eastern sides of mountains?
In California most precipitation falls on the eastern sides of mountains
Are the eastern sides of mountains usually drier than the western sides?
Yes, in many regions the eastern sides of mountains are drier than the western sides. This is because as air ascends on the windward (western) side, it cools and releases precipitation, creating a rain shadow effect. The descending air on the leeward (eastern) side is drier and results in less rainfall.
