Understanding Glacial Features: Erosional Landforms and Formation Process

Glacial Landform Formation and Processes - A comprehensive guide exploring the formation of major erosional landforms of glacier and their development processes.

  • Types of glaciers in Geography play a crucial role in shaping mountain landscapes through erosion processes including abrasion, freeze-thaw, and plucking
  • The formation of key features like arêtes, corries, U-shaped valleys, ribbon lochs, and hanging valleys demonstrates the powerful erosive capabilities of glaciers
  • These glacial landforms examples are primarily formed in North and Northeast-facing locations due to favorable conditions for snow accumulation
  • The process involves the transformation of snow into neve ice and eventually glaciers, which then shape the landscape through various erosional mechanisms

Page 2: Corrie Formation and Pyramidal Peaks

This page expands on corrie formation and introduces pyramidal peak formation process. It explains how corries develop their characteristic armchair shape and the formation of bergschrund crevasses.

Definition: A bergschrund is a crevasse that forms where the moving glacier pulls away from the mountain's back wall.

Example: Red Tarn is cited as an example of a corrie.

Highlight: Pyramidal peaks form when three or more corries develop back-to-back, creating a pointed summit.

Example: Stob Ban in Fort William is given as an example of a pyramidal peak.

Page 3: U-Shaped Valley Formation

The page focuses on how V-shaped river valleys are transformed into U-shaped valleys through glacial erosion.

Definition: A U-shaped valley is a glacially eroded valley with steep sides and a flat bottom.

Vocabulary: Misfit stream - The original river that appears too small for the valley it occupies after glaciation.

Example: Glen Nevis is provided as an example of a U-shaped valley.

Highlight: The process involves the elimination of interlocking spurs and the widening of the valley floor.

Page 4: Ribbon Loch Formation

This page begins to explain the formation of ribbon lochs, another significant glacial landform. The text emphasizes the importance of north and northeast-facing valleys in the formation process.

Highlight: The formation process follows similar patterns of erosion as other glacial features, involving abrasion, freeze-thaw, and plucking.

Vocabulary: Ribbon loch - A long, narrow lake formed by glacial erosion.

Ribbon Loch Formation

Ribbon lochs represent distinctive glacial landforms examples created through differential erosion patterns.

Definition: A ribbon loch is a long, narrow lake formed when glaciers erode deeper into areas of softer rock within a U-shaped valley.

Highlight: The formation process involves selective erosion where glaciers excavate deeper channels in areas of weaker rock.

Page 1: Formation of Arêtes and Corries

The page details the formation processes of two major glacial landforms: arêtes and corries. The process begins with snow accumulation in north and northeast-facing hollows, where shade preserves the snow cover.

Definition: An arête is a sharp, knife-edge ridge formed when two corries develop back-to-back on a mountain.

Vocabulary: Neve ice - Compressed snow that forms through the weight of accumulated snowfall.

Example: Striding Ridge is provided as a real-world example of an arête.

Highlight: Three main types of glacial erosion are introduced:

  • Abrasion: Rock fragments in ice act like sandpaper
  • Freeze-thaw: Water freezing and expanding in rock cracks
  • Plucking: Glacier freezing to and pulling away rock

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Samantha Klich

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀

THE QUIZES AND FLASHCARDS ARE SO USEFUL AND I LOVE THE SCHOOLGPT. IT ALSO IS LITREALLY LIKE CHATGPT BUT SMARTER!! HELPED ME WITH MY MASCARA PROBLEMS TOO!! AS WELL AS MY REAL SUBJECTS ! DUHHH 😍😁😲🤑💗✨🎀😮

This app is phenomenal down to the correct info and the various topics you can study! I greatly recommend it for people who struggle with procrastination and those who need homework help. It has been perfectly accurate for world 1 history as far as I’ve seen! Geometry too!
