Where are the major mountain ranges located?

How many mountain ranges can you name?

Objectives

• All students must be able to name the main mountain ranges from around the world

• Most students should be able to explain how plate movements lead to the formation of mountains

• Some students could explain why we have mountains in the UK despite being far from plate boundaries

• STRIPE – Innovative learner - Use different learning styles

Specification key ideas

• 2.1 Mountains are found in particular areas of the world.

• 2.2 There are major mountain ranges on most continents.

Starter

• Complete a map from memory exercise to find out where 10 of the world’s main mountain ranges are located

• Work in groups of four, with one student going to look at the main map at a time, then adding whatever they can remember to your outline map

• Swap maps and mark them – give one mark for each range accurately located and one for each range that is named

What is the relationship between mountains and plate boundaries?

• You will be given a map showing the plate boundaries

• Add the main mountain ranges to this map - Rockies, Andes, Alps, Himalayas, Great Dividing Range, Pyrenees and Atlas.

• Describe the relationship shown on your map

What can you remember about plate boundaries and volcanoes

from years 8 and 9?

Watch http://www.youtube.com/watch?v=gyT8Xs6Ab-k to recap the key points about the structure of the earth and plate boundaries in song!

Task

• Divide a page into four and use diagrams & writing to show what happens at constructive, destructive (collision), destructive (subduction) and conservative boundaries (see the Geog.3 textbook for help).

• Include information about faulting, folding, volcanic activity and earthquakes on your diagrams.

Recapping plate boundaries

• Recap – have a go at plate boundaries kung fu – see http://www.youtube.com/watch?v=STDgv0Nsuyg

How do fold mountains form?

• Look at page 45 in the black textbook to find out how fold mountains form.

• Watch http://www.youtube.com/watch?v=jVyBsUgD7Gk

Fold mountains in the Andes

• The Andes Mountains run the length of the West Coast of South America, rising in the North in Colombia and finishing in Chile and Argentina in the South.  

• They are world's longest mountain range running for over 7,000km and covering 6 countries. 

How did the Andes form?

• The mountains have been formed as a result of the convergence of the Nazca plate and the South American plate. 

• The heavier oceanic crust of the Nazca plate is pushed towards the South American plate, and because it is denser is subducted underneath. 

• The South American plate is less dense so sits on top of this subduction zone, but the rocks of the South American plate have been folded upwards and crumpled into fold mountains.

Andes facts and figures!

• There is a sequence of volcanoes and fold mountains, rising up to 6962m at Aconcagua. 

• The trench (marking the boundary between the Nazca and South American plates) to the West of the Andes mountains is called the Peru-Chile Trench, and reaches an incredible depth of 8066m under the sea level.

Task

• Answer the following exam question in your book:

• Explain how mountains have formed in an area which you have studied. You may wish to use a diagram. (6 marks)

• Top tip – include fold mountains and volcanoes for top marks.

Peer assessment• Level 1: Process of folding or volcanic

activity briefly explained, but not in relation to a specific area (1-2 marks)

• Level 2: Process of folding or volcanic activity is clearly explained in relation to a specific area (3-4 marks)

• Level 3: Processes of folding and volcanic activity are both clearly explained in relation to a specific area, with good use of locational detail (5-6 marks).

Feedback about answer:

• What went well (WWW)?

• Even better if (EBI)?

What is the difference between folding and faulting?

• Watch http://www.youtube.com/watch?v=rG8pZxbw3xA to find out!

• Summarise the difference in your book – you may wish to use diagrams.

Homework• Working in pairs or individually, produce a revision

resource to explain how The Andes mountains formed –

• VISUAL LEARNERS (IMAGES)– why not make a poster, an annotated diagram or a series of illustrations?

• VISUAL LEARNERS (WRITING) – why not write an explanation of the process?

• AUDITORY LEARNERS – why not write a poem or a rap and record it to share?

• KINAESTHETIC LEARNERS – why not make a model or a series of models?

Reflection

• Why are there mountains in Britain when we aren’t on a plate boundary?

• Have we been innovative learners today?
