Transcript of MOUNTAINS

MOUNTAINS
A GLOBAL ENVIRONMENT
Mountains
An Introduction...
Mountain environments occupy 24% of the Earth's surface
The Mountain environment contains unique plant and animal species, and is rich in biodiversity.
Mountain inhabitants are highly adapted to their specific local environment, leading to greater cultural diversity.
As these areas become more accessible and population pressures increase, sustainable management is essential.
See-Think-Wonder
For each photo, discuss as a class:

1. What do you see?

2. What do you think?

3. What does it make you wonder?
The Earth's Structure
Movements of the Earth's Crust
The Earth's thin crust is broken into eight segments

These are called
plates

The plates travel slowly across the Earth's surface

This movement is caused by currents in the earth's liquid mantle

The name given to this process is
plate tectonics
Key Terms
Geomorphic processes:
modify the earths crust and shape of the land surface (through physical and chemical reactions)

Mountain range:
a group of mountains together

Altitude:
height above sea level

Local relief:
the difference in height between the highest and lowest points in a particular area.

Tectonic plates:
large, moving areas of the Earth’s surface

Types of plate movements
The earth's plates move in different ways:

some plates move towards each other
some move apart
some slide past each other

The places where plates meet are known as plate margins.

There are four different types of plate margins.
Task
1. Draw a table in your book like the one below
2. Use pages198-199 of your textbook to complete the table
Group Task: Find-the-Facts
Your teacher will allocate you a group

Your task:
1. Use 8.1.02 (page 185) and 8.1.10 (page 188) only.
2. Your group is to find and record as many facts as possible using the given stimulus, in the given period of time (decided by your teacher)

The Catch....?
You can only use the information on the two maps
You CANNOT make assumptions
You CANNOT use prior knowledge
You CAN ONLY record factual information you find on the two maps
Each group member must write down the facts for them to be counted
Who WINS?
At the end of the task, each group member will have a turn at sharing a fact to the rest of the class.

It is up to the class to decide whether it is a
FACT
or an
ASSUMPTION
- so be careful, if it is an assumption it won't count :-)

The group with the most facts at the end
WINS
Fault Mountain
Draw the following diagram
Fold Mountains
Draw the following diagram
Mountains
The world's greatest mountain ranges are found along plate margins. As the plates press against each other, the pressure increases. The layers of rock are compressed and forced upwards, folding and faulting as they move

Fault mountains
Are fractures in the rock structure
The landform characteristics of fault mountains include block mountains and rift valleys (see page 188 of textbook)

Fold mountains
Are wave-like patterns in the earth's crust

Mountain Climbing Diary - Freaky Peaks!!
To be completed once a week from weeks 2-8. Minimum of 3 paragraphs.
Will be checked
Friday
of each week by your Geography Teacher. Instructions are on eVe.
Topics for each post include –
Week 2
– Mountain Location (any mountain, include description, location (lat and long) and images)
Week 3
– Mountain Climbing Conditions (Climate of the mountain area, steepness of the slopes, height, plan to climb)
Week 4
– Plants and animals (What are you going to see on the climb, or what have you seen while climbing, images)
Week 5
– Equipment (What is needed to climb the mountain, detailed description and two geographical tools.)
Week 6
– Tourists (Negative impacts 3)
Week 7
– Tourists (Positive impacts 3)
Week 8
– The Locals. (Who are the locals and how do they interact with the mountain?)
