Corrie 🗻

Question 1

How does a small hollow on the side of a mountain fill with ice? 🧊

Answer 1

Snow collects in a small natural hollow on the side of a mountain. Over time further snow collects in the hollow. This extra weight compresses the snow underneath, turning it to ice. 🧊

Question 2

How is a corrie made?

Answer 2

1. Snow gathers in a hollow then turns to ice.
2. Material from the base of the hollow is plucked out by the ice and abrades the hollow making it deeper.
3. Eventually the ice outgrows the hollow and goes down the slope due to gravity
4. When the ice melts it leaves a deepened hollow called a corrie
5. Sometimes the corrie fills up with water to make a lake. This is called a tarn
