23
Q

What is the description of a converging plate boundary?

A

(destructive)
Two tectonic plates moving towards each other.
2 Continental plates: plates collide and the land is forced to rise, creating a mountain.
1 continental + 1 oceanic: oceanic plate is less dense than continental so is forced to slide under continental

23
Q

What is subduction?

A

When the less dense plate (oceanic) is forced to slide under the more dense plate (continental).

23
Q

What is the description of a transforming plate boundary?

A

(sliding)
Two tectonic plates sliding past each other - pressure builds up and is eventually released in the form of an earthquake.

23
Q

What are some examples of a diverging boundary?

A

Oceanic: Mid-Atlantic Ridge: Eurasian + North American plate
Continental: Great-Rift Valley: African drifting from Arabian plate

23
Q

What are some examples of a converging boundary?

A

Continental: Eurasian + Indian plates colliding form Himalayas
Subduction: South American (continental) and Nazca being subducted

24
Q

What are some examples of a transforming boundary?

A

Pacific plate and North American plate - California

25
Q

What is the description of a diverging plate boundary?

A

(constructive)
The tectonic plates are moving away/apart from one another.
2 Oceanic plates: molten rock seeping through cracks, cools and forms new land (i.e under mountain)
2 continental plates: molten rock seeps through crust, it cools and forms volcano or rift

26
Q

Explain aspect of the economic value of the Grand Canyon.

A
  • tourism creates $467 million in annual economic benefit (helicopters flying over)
  • also creates employment opportunities
  • tourists can stay in the village and hike/camp in Havasu Canyon
  • railway depot in Grand Canyon
27
Q

Definition of a Fold Mountain.

A

Fold mountains are created by upward pressure where two tectonic plates collide. As the plates converge, layers of rock are buckled and pushed upwards creating fold mountains. Most of the world’s highest mountain ranges are fold mountains.

28
Q

Definition of a Block/Fault Mountain.

A

Block mountains are created when cracks in the Earth’s crust known as faults force blocks of land upwards. Rocks the are cooler - because they are closer to the surface - tend to crack and break apart when compressed from the sides. Rather than folding, they are often lifted up in giant blocks along fault lines to create block mountains.

29
Q

Definition of a Volcanic Mountain.

A

Volcanic mountains are created when magma pushes it’s way up from beneath the Earth to the crust. The material that comes out of a volcano builds up the Earth’s surface, creating new land and new landforms.

30
Q

Explain weathering.

A

Weathering involves the physical or chemical breakdown into smaller pieces of rocks that do not undergo transportation from their original position.

31
Q

Explain physical weathering.

A
  • temperature change: repeated heating and cooling to break down
  • freeze-thaw action: water in cracks freezes
  • organic action: roots of plants grow within a plant, causing parts to break off
32
Q

Explain chemical weathering.

A

A reaction between the rock and the water/air. This causes pieces of rock to break away.

33
Q

Explain the process deposition.

A

The process by which eroded material is added to a landscape.
e.g. islands, sand dunes and beaches

34
Q

Explain the process erosion.

A

Erosion is the transportation of material that has been weathered from one place to another by wind, water or ice. The gradual wearing away of rock
Wind: beaches, deserts
Water: beaches - waves, high rainfall, near a river -basin
Ice: mountains, glaciers

35
Q

  • recreational: boating, surfing, swim, fishing, bird watching
39
Q

Human uses of mountain landscapes:

A
  1. Mountains are popular tourist destinations and tourism generates large incomes for many countries. (ski resorts -Thredbo, Alps)
  2. About 1/10 of the world’s population lives in mountainous areas (Sherpa in Nepal)
  3. Fast flowing mountainous rivers provide a source of power (hydro electricity)
  4. Minerals and metals such as coal, gold, silver and tin are often found in mountain landscapes.
  5. More than half of the worlds population relies on fresh water that falls from mountains and flows into rivers.
  6. Rainfall is often hire in mountain areas so they make ideal places for some types of farming, e.g. rice farming.
40
Q

What is an earthquake?

A

A sudden release of energy in the earth’s crust creating vibrations.

41
Q

What are volcanoes?

A

A cone shaped feel all mountain formed when molten magma in the earth’s mantle is forced opening event in the lithosphere. Volcanoes are one of the Earth’s most violent ages of change. They create, alter and destroy landscapes, modify climates and change people’s lives.

42
Q

What are subduction zones?

A

Some volcanoes are formed when oceanic plate is pulled underneath the continental plate (subduction). As the crust is forced down, it heats up and becomes magma. It can then rise to the Earth’s surface through the magma chamber.

43
Q

Explain volcanoes in rift areas.

A

Volcanoes are formed when two plates move away from each other. The molten lava rises to the surface to the space between the plates.

44
Q

What are hotspots?

A

Although most volcanoes are formed on plate boundaries, some are located in the middle of plates a long way from plate boundaries. These volcanoes haven’t formed above a hotspot (an area of the crust where it is quite thin and volcanic activity can sometimes occur). Volcanoes move as the plates slowly move over the hotspot and overtime, a chain of volcanoes can form.

45
Q

What is a shield volcano?

A

A broad, flat cone formed by runny lava coming slowly to the surface and spreading widely before cooling.

46
Q

What is a composite volcano?

A

The most common volcano. A cone shaped mountain built up by many eruptions and consisting of layers of lava and ash.

47
Q

What is a dome volcano?

A

A tall, convex-shaped cone formed by thick and treacle like lather calling quickly and so not flowing far away

48
Q

What is a cinder volcano?

A

A steep sided, cone-shaped hill built up by the cinders ejected from a volcano.
