memes 100% correct

Thanks

thank uuu

Thanks "MeMes" <33

still good 100% thanks memes

thank u so much @memes

good

Glacial erosion is a powerful force that shapes the Earth's landscape. It occurs when glaciers, large masses of ice, move across the land, scraping and carving the surface. This process creates a variety of distinct landforms. Let me explain how glacial erosion works and the landforms it produces:

1. U-shaped Valleys: Glaciers erode V-shaped river valleys into U-shaped valleys. As a glacier moves down a mountain, it carves out the sides and bottom of the valley, creating a broad, flat-bottomed U-shaped valley.

2. Cirques: These are bowl-shaped hollows at the head of U-shaped valleys, typically found on mountainsides. Cirques are formed as glaciers carve out the mountainside, leaving behind a steep, curved basin.

3. Arêtes: As glaciers erode surrounding mountains, they often create sharp, narrow ridges called arêtes. Arêtes form when glaciers erode parallel valleys on either side of a mountain, leaving a narrow ridge between them.

4. Horns: Horns are sharp, pyramid-shaped peaks formed by the erosive action of glaciers on multiple sides of a mountain. The repeated erosive action causes the mountain to become steep and jagged.

5. Hanging Valleys: These are smaller, tributary valleys that enter a larger U-shaped valley but end abruptly above its floor. Hanging valleys are formed when small glaciers erode vertically while the main glacier carves the larger valley.

6. Moraines: Glaciers actively transport large amounts of rock and debris as they move. This material is deposited along the edges and base of the glacier, forming ridges called moraines. Terminal moraines mark the farthest extent of a glacier, while lateral and medial moraines form along its sides.

By understanding these processes, you can identify and recognize these glacially influenced landforms in different landscapes around the world.
