§6.1 Geysers and canyons

Test results:

 the results will be discussed for each group next week

Lesson goals:

1. Review §6.1

2. Discuss various landforms

What should you understand at the end of the lesson?

What is the relationship between landforms and climate?

Project

Climate:
Pick a city in the centre of both regions and show a climate graph of the city.
Use the Köppen climate system to describe and explain the various climates in the regions.
Explain in what way climate change effects the regions.

Landscape:
Show a map of the region showing the landscape.
Show two pictures of each landscape.
Describe the main features in the landscape and explain how they have been formed.
Explain how weathering, erosion and sedimentation have effected the landscape over time.

The West of the USA

For what reason is the monolith still standing?

1. It consists of hard, resistant rock
2. There is not enoug rainfall in this region
3. The monolith has recently formed
4. The monolith consists of solidified sand

How was this mushroom rock formed?

1. By chemical weathering
2. By temperature differences
3. It was shaped by human beings
4. By sand eroding the sides of the rock.

In what way does ice contribute to the formation of hoodoos?

01:49

The expanding effect of ice on rock is considered

1. chemical weathering
2. erosion
3. sedimentation
4. mechanical weathering

A Hoodoo

It is formed by water and ice erosion
Plateau uplifted, creating cracks. The water wears away softer parts of the soil. Temp drops +> water turns to ice (like a flexing muscle) => formation of a finn (like a shark finn)
 More water and ice => formation of a ‘window’. Roof collapses => Hoodoo

Relationship climate and landforms

BS / BW (Köppen)

Steppe climate / desert climate

• very little / no rainfall
• extreme temperature amplitude between day and night
  

Cs / D

Mediterranean climate

• hot and dry in summer
• wet in winter
  

Continental climate

• hot in summer
• cold in winter
  

What is the relationship between a large temperature amplitude and mechanical weathering?

What is the relationship between moisty weather and chemical weathering?
