What do you notice about this glacier?

To identify and describe landforms created by glacial deposition. KEY IDEAS & QUESTIONS To identify and describe landforms created by glacial deposition. To explain how landforms of glacial deposition are formed – moraine, drumlins and erratics.

3/4 Identify and describe moraine, a drumlin and an erratic. 5/6 Identify and describe all 3 types of moraine, a drumlin and an erratic. Give a basic explanation of how these features are formed by deposition. 7+ Identify and describe all 3 types of moraine, a drumlin and an erratic. Give a more detailed explanation of how these features are formed by deposition.

Moraines A B C Lateral Moraine: Long mounds of material eroded from the valley walls are deposited on the side of the glacier. Medial Moraine: When 2 glaciers meet lateral moraines join to form a line of material running along the centre of the glacier. Terminal Moraine: Builds up at the end of the glacier. As it melts the material is dropped off in a large mound.

Drumlins A drumlin is an elongated hill made up of glacial deposits. The largest ones can be over 1km long, 500m wide & 50m high.

Drumlins are round, blunt and steep at the upstream end and tapered, pointed and gently sloping at the downstream end.

Drumlins are often found in groups – a ‘drumlin swarm’ or ‘basket of eggs’.

Erratics Erratics are rocks that have been picked up by a glacier, carried along and dropped in an area (possibly hundreds of miles away) where there is a completely different rock type.

Erratics often look out of place - a large boulder on it’s own

Eric The Erratic’s Amazing Adventure

Imagine you are a children's author. Write a story explaining how Eric the Erratic travelled a hundred miles to a new home. Eric’s journey should appeal to your young audience – but also teach them some key facts about glaciation. 1. Title Box – Eric The Erratic’s Amazing Adventure 2. Eric is plucked from the side of the mountain by the glacier 3. Eric is scraped along the rock underneath the glacier (abrasion) 4. Eric travels with the moraines 5. Eric stops to hang out with the Drumlins 6. The glacier melts and drops Eric off in his new home where get’s to hang out with lots of new rocks!

Independent Learning Opportunity Flexible This week its all about the erratics… Eric: Finish off Eric The Erratic’s Amazing Adventure. Okotok: Find out about ‘Big Rock’, otherwise knows as Okotok’s Erratic in Canada. Merton: Find out about Merton Rock – the UK’s largest glacial erratic. 2 & 3 can be done as a PowerPoint, on paper, a poster or fact file Bring your work in to gain an ILO credit  Have this ready to hand in for:
