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

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=rG8pZx
bw3xA 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?
