1. STATION 1 FAULT BLOCK MOUNTAINS

2. STATION 1 - FAULT BLOCK MOUNTAINS
HOW DO MOUNTAINS FORM???
(Write down what is in red)
The great mountain ranges of the world were created because of the constant but very slow movement of the Earth's plates. When the plates of the Earth collide the crust becomes high mountain ranges. The roots of the world's great mountain ranges contain some of the oldest rocks on the surface of the Earth. Some of these rocks are over 3.5 billion years old!! These rocks were once buried deep inside the Earth and have been raised into mountains by the collisions of the plates.
These plates travel at a very slow rate about 1 to 4 inches per year. The Indian Subcontinent was a very fast mover, clipping along at over 4 inches per year. When it slammed into the Eurasian plate over 24 million years ago the collision built the highest mountain range in the world, the Himalayas. In fact, the Himalayas are still climbing higher and higher today.

3. STATION 1 - FAULT BLOCK MOUNTAINS
DEFINITION
Fault-block mountains form along fault lines where blocks of rock either fall, or are thrust up, or slide. Fault blocks are very large blocks of rock, created by tectonic stresses in the Earth's crust. Large areas of bedrock are broken up into blocks by faults.

8. STATION 2 FOLD BLOCK MOUNTAINS

9. STATION 2 - FOLD BLOCK MOUNTAINS
DEFINITION
Fold mountains are mountain ranges that are formed when two of the tectonic plates that make up the Earth's crust push together at their border. The extreme pressure forces the edges of the plates upwards into a series of folds.
Fold mountains are created through a process called "orogeny." An orogenic event takes millions of years to create a mountain range because tectonic plates move only centimeters every year.
Fold mountains are the most common type of mountain on Earth.

13. STATION 3 PLATEAUS

14. STATION 3 - PLATEAUS DEFINITION
Plateau - land formation known as tableland
-characterized by an elevated and flat plain of land that resembles a table.
- a large or small raised area of flat land that is separated from the rest of its surrounding land by slopes on each side
Mesa - a small plateau that is more isolated from the surrounding landscape and has distinct cliff type edges to it.
Butte - larger plateau than a mesa and has steeping slope edges that separate it from the surrounding landscape.

15. STATION 3 - PLATEAUS HOW DOES A PLATEAU FORM???
 There are different ways in which plateaus can develop but in each case the creation of the land formation is not an instant geological act as it can take millions of years for these raised, flat areas of land to be built.
1) When magma pushes up towards the surface of the Earth’s crust. The magma does not break through but instead raises a section of the crust up as it rises and creates a plateau.
2) Another way in that can create plateaus is when lava breaks through the Earth’s crust and builds upon itself over and over to form a raised land area.
3) Millions of years of wind and water erosion can create a plateau.
a) Water flowing in specific patterns will break down layers of rock over time and carve out channels that will dig deeper down. As the water digs its way down, steep slopes are created and that forms the edges of the plateau.
b)Wind affects the land’s layers of rock much in the same way that water does, as the water exposes more layers, the wind erodes the area more and helps in the steepness of the sides that make the base of the plateau.

16. STATION 3 - PLATEAUS EXAMPLE of Plateau:
The Colorado Plateau is extremely ancient as a distinct mass of continental crust, at least 500 million years old.

19. STATION 4 CANYONS

20. STATION 4 - CANYONS DEFINITION - Also known as a gorge
- Also known as a gorge
- a deep ravine between cliffs often carved from the landscape by a river
-rivers have a natural tendency to reach a baseline elevation, which is the same elevation as the body of water it will eventually drain into. This forms a canyon
- elevation is the height of something above sea level

21. STATION 4 - CANYONS
Most canyons were formed by a process of long-time erosion from a plateau level. The cliffs form because harder rock strata that are resistant to erosion and weathering remain exposed on the valley walls.

EXAMPLE of Canyon:
The Grand Canyon in Arizona is an example of a large canyon where the Colorado River eroded the Colorado Plateau.

24. STATION 5 Weathering: Chemical

25. STATION 5 – Chemical Weathering
DEFINITION
Chemical weathering breaks down rocks by changing their composition. Oxidation and the action of acids are important chemical weathering processes.
Oxidation – rocks exposed to air can react with the oxygen
Many rocks contain iron which will rust when exposed to oxygen making the rock weaker
Acids – when carbon dioxide combines with water, carbonic acid is formed which can dissolve some minerals like Limestone and marble

26. STATION 5 – Chemical Weathering
EXAMPLE of Chemical Weathering:
A sinkhole is a natural hole that forms in the Earth's surface as a result of the chemical weathering of carbonate rocks like limestone, as well as salt beds or rocks that can be severely weathered as water runs through them.

EXAMPLE of Chemical Weathering:
A sinkhole in Windemere, Florida that formed overnight on May 3, 2012

28. STATION 5 – Chemical Weathering
EXAMPLE of Chemical Weathering:
These marble tombstones can no longer be read as a result of chemical weathering.

29. STATION 5 – Chemical Weathering
EXAMPLE of Chemical Weathering:
The rocks are red because of the high concentration of iron oxides, which formed during the oxidation of the iron in the rock.

30. STATION 6 Weathering: Physical

31. STATION 6 – Weathering: Physical
DEFINITION
Mechanical weathering is the process of breaking down of rock by physical changes.
Examples: frost action, actions of plants and animals
Frost action – the repeated freezing and thawing of water, it breaks rock apart when water seeps into the cracks and then freezes and expands
Plants & Animals – growth or roots may widen cracks, burrowing animals turn over soils

35. STATION 7 EROSION

36. STATION 7 – EROSION
The gradual wearing away of land surface materials, especially rocks, sediments, and soils, by the action of water, wind, or a glacier. Usually erosion also involves the transport of eroded material from one place to another, as from the top of a mountain to an adjacent valley, or from the upstream portion of a river to the downstream portion.

37. STATION 7 – EROSION
EXAMPLE of Erosion

38. STATION 7 – EROSION
Buttes, Mesas,and Canyons are landforms resulting from erosional and weathering activity and are called 'erosional landforms'.

39. STATION 8 SOIL

40. STATION 8 – SOIL
DEFINITION
Soil is the loose, weathered rock that can support the growth of rooted plants. Soil is a mixture of weathered rock, humus, air, water, and living things. Bacteria, fungi, worms, and insects help in the formation of soil.

41. STATION 8 – SOIL HOW IS SOIL FORMED?
Soil forms as rock is broken down by weathering and mixes with other
materials on the surface. It is constantly formed wherever bedrock is
exposed. Soil formation continues over a long period, and gradually soil
develops layers called horizons. A soil horizon is a layer of soil that differs in color and texture from the layers above or below it.
