Tsunami

Holly Simms:

==Key Stage 4==
===Meaning===
A '''tsunami''' is a giant [[wave]] caused by an [[earthquake]] or [[landslide]] under the [[Sea Bed|sea bed]].

===About Tsunamis===
[[Earthquake]]s under the [[Sea Bed|sea bed]] cause a large volume of water to be displaced due to a large output of [[energy]]. This [[energy]] creates a large wave that travels through the water at up too 500kmph.
When tsunamis reach the [[coast]] [[friction]] builds between the much more shallow [[Sea Bed|sea bed]] and the high speed energy of the wave as there is less water for the [[energy]] to travel through. This friction causes the wave the to slow down as friction builds and therefore as it slows down the height of the wave increases. After this increase in height Tsunamis can reach up to 100ft as they come in contact with land.
When they reach land Tsunamis flood the area [[local]] to the [[coast]] and can cause large amounts are destruction including damage to people's [[property]], damage to the [[local]] [[environment]], and loss of life.

Earthquake

Holly Simms: /* About Earthquakes */

==Key Stage 2==
===Meaning===
An [[earthquake]] is when the ground shakes.

==Key Stage 3==
===Meaning===
An [[earthquake]] is when the ground shakes.

===About Earthquakes===
: [[Earthquake]]s are usually caused by [[Tectonic Plate|tectonic plates]] rubbing against each other.

==Key Stage 4==
===Meaning===
An '''Earthquake''' is when the ground undergoes a violent shaking motion. This often results in damage to the [[local]] environment and severe loss of life.

===About Earthquakes===
'''Earthquakes''' occur along all three types of [[Tectonic Plate Margin]] when tension builds up as the [[Tectonic Plates|plates]] move.

At [[Destructive Plate Margin]]s as the two plates move down past each other into the mantle [[friction]] causes tension to build up and therefore the plates get stuck. As the plates are released and jerk away from each other they release shock waves that that spread from the [[Focus|focus]] deep in the [[mantle]] where the plates are coming together. The shock waves are then felt on the surface of the [[crust]] and they are most strongly felt at the [[Epicentre]] which is the point directly above the [[focus]]. This is an '''earthquake'''.

At [[Conservative Plate Margin]]s as the plates grind past each other [[friction]] causes tension to build between the plates as they move and this means that they eventually become stuck. As the plates are released and jerk away from each other they release shock waves that that spread from the [[Focus (Earthquake)|focus]] deep in the [[mantle]]. The shock waves are then felt on the surface of the [[crust]] in the form of an '''earthquake'''. The shock waves are most strongly felt at the [[Epicentre]] which is the point directly above the [[Focus (Earthquake)|focus]].

At [[Constructive Plate Margin]]s the plates are moving away from each other and this causes cracks in the plates as they move. Tension then builds in these cracks and is eventually released in the form of shock waves that can be felt of the surface of the earth at the [[crust]] as an '''earthquake'''.

Earthquakes come in a variety of strengths therefore there is a scale that shows you how strong each earthquake is and how much damage it is likely to do. This is called the '''moment magnitude scale'''. This scale measures the amount of energy released by an earthquake and is measured logarithmically. This means that a magnitude 2 earthquake is ten times stronger than a magnitude 1 earthquake. Earthquakes below magnitude 6 only cause slight damage to buildings and earthquakes magnitude 7 and above can cause high levels of damage and large loss of life.

Conservative Plate Margin

2019-07-31T11:32:48Z

Holly Simms:

==Key Stage 4==
===Meaning===
A '''conservative plate margin''' is a location where two [[Tectonic Plates]] slide past one another but not towards one another.
===About Conservative Plate Margins===
At '''Conservative Plate Margins''' the [[Tectonic Plate|plates]] either move past each other in opposite directions or are sliding along next to each other in the same direction but at different speeds. Conservative Plate Margins are often the cause of very violent [[Earthquake]]s. This is because as the plates move past each other [[Friction|friction]] builds and this can lead to the plates becoming stuck next to each other. This subsequently leads to an [[Earthquake]] as [[energy]] is released as the plates jolt past each other. The [[West]] [[Coast]] of the USA is a key example of a conservative plate margin and is an area that suffers from regular large [[Earthquake]]s.

==Key Stage 4 Geography==
===About the Mid-Atlantic ridge===
The '''mid-Atlantic ridge''' is a [[Constructive Plate Margin]] that largely runs along the floor of the [[Atlantic Ocean]] with some areas that elevate above the water. In the [[Atlantic Ocean|north Atlantic]] it separates the Eurasian and North American [[Tectonic Plate| plates]] and in the [[Atlantic Ocean|south Atlantic]] it separates the African and South American [[Tectonic Plate|plates]]. All of these [[Tectonic Plate|plates]] are still moving apart and therefore the ridge grows by [[Approximate|approximately]] 2.5cm every year.

Holly Simms:

==Key Stage 4==
===Meaning===
A '''constructive plate margin''' is the location where two [[Tectonic Plate]]s are moving away from one another.

===About Constructive Plate Margins===
At constructive plate margins two plates are pushing away from each other and therefore opening a large gap between then. [[Magma]] then rises from deep in the earth in the [[mantle]] to fill this gap and new [[crust]] is formed. [[Volcano]]s are often found at constructive plate margins as the rising [[magma]] often creates [[Volcanic Eruption|eruptions]]. A key example of a constructive plate margin is the [[mid-Atlantic ridge]] where the new crust that has formed is visible in the form of a long ridge of land under the [[Atlantic Ocean]].

Magma Chamber

2019-07-30T16:45:40Z

Holly Simms:

==Key Stage 4 Geography==
===Meaning===
A '''Magma Chamber''' is a hollow area deep in the Earth's [[mantle]] that is filled with molten [[magma]]. This [[magma]] will eventually rise to the surface of the [[crust]] through [[vents]] and form a volcano.

Destructive Plate Margin

2019-07-30T16:44:08Z

Holly Simms:

==Key Stage 4 Geography==
===Meaning===
A '''destructive plate margin''' is a location where two [[Tectonic Plates|tectonic plates]] are moving towards one another and eventually meet and one is pushed under the other in a process called [[Subduction|subduction]].

==About Destructive Plate Margins==
[[Subduction]] occurs at '''destructive plate margins''' when an [[Oceanic Plate]] and a [[Continental Plate]] meet. Because the [[Oceanic Plate]] is more [[dense]] it is pushed beneath the less [[dense]] [[Continental Plate]]. As the plates move past each other in a [[Friction]] causes the [[Oceanic Plate]] to be melted and destroyed and therefore [[magma]] is created. The [[magma]] in the [[Magma Chamber|magma chamber]] then rises and [[volcano]]s are often formed.

A [[volcano]] is a mountain made from [[lava]] that has cooled to become [[rock]].

==Key Stage 3==
===Meaning===
A [[volcano]] is a mountain made from [[lava]] that has cooled to become [[igneous]] [[rock]].

===About Volcanoes===
: [[Volcano]]es are usually found near the boundaries between [[Tectonic Plate|tectonic plates]].

Once a volcano is formed it goes through 3 stages of existence :
: 1. Firstly as a volcano is [[Volcanic Eruption|erupting]] or has recently erupted it is known as an [[Active Volcano]].

: 2. Secondly when a volcano is not currently erupting but is due to erupt again within a period of ten thousand years since its last eruption it is known as a [[Dormant Volcano]].

: 3. Finally if a volcano has not erupted in over 10,000 years it is classified as an [[Extinct Volcano]]. This means that it will never erupt again.

===About Volcanoes===

===How Volcanoes are formed===
'''Volcanoes''' are formed along 2 different types of [[Tectonic Plate Margin|tectonic plate margin]]; [[Destructive Plate Margin]]s and [[Constructive Plate Margin]]s.

At [[Destructive Plate Margin]]s more [[dense]] [[Oceanic Plate|oceanic plate]] moves under the less [[dense]] [[Continental Plate|continental plate]]. As this happens the [[Oceanic Plate|oceanic plate]] is melted and a lot of [[magma]] forms in a large pool. This [[magma]] then rises towards the surface of the [[crust]] through cracks in the [[crust]] called [[vents]]. As this [[magma]] reaches the surface an extremely violent [[Volcanic Eruption]] is created due to high [[pressure]] that built up as the [[magma]] moved through the [[vents]] being released. Once this [[Volcanic Eruption]] had occurred the [[lava]] that was produced cools and forms [[rock]] in the form of a mountain. This is a [[Volcano]]

At [[Constructive Plate Margin]]s two [[Tectonic Plate]]s are moving away from each other and this creates a very large and deep gap. [[Magma]] rises up towards the surface of the earths [[crust]] through this gap. This then causes the [[magma]] to erupt as it reaches the surface of the [[crust]]. This is a much less violent eruption as the [[magma]] has risen through a much wider gap than the size of the [[vents]] at the [[Destructive Plate Margin]] and therefore less [[pressure]] is built up and the [[volcanic eruption]] is less explosive. The [[lava]] that has erupted then solidifies into rock and a '''volcano''' is formed.

As this [[magma]] reaches the surface an extremely violent [[Volcanic Eruption]] is created due to high [[pressure]] that built up as the [[magma]] moved through the [[vents]] being released. Once this [[Volcanic Eruption]] had occurred the [[lava]] that was produced cools and forms [[rock]] in the form of a mountain. This is a [[Volcano]]

At [[Constructive Plate Margin]]s two [[Tectonic Plate]]s are moving away from each other and this creates a very large and deep gap. [[Magma]] rises up towards the surface of the earths [[crust]] through this gap. This then causes the [[magma]] to erupt as it reaches the surface of the [[crust]]. This is a much less violent eruption as the [[magma]] has risen through a much wider gap than the size of the [[vents]] at the [[Destructive Plate Margin]] and therefore less [[pressure]] is built up and the [[volcanic eruption]] is less explosive. The [[lava]] that has erupted then solidifies into rock and a volcano is formed.

===Meaning===
A [[volcano]] is a mountain made from [[lava]] that has cooled to become [[igneous]] [[rock]].

===About Volcanoes===
[[Volcano]]es are usually found near the boundaries between [[Tectonic Plate|tectonic plates]].

===How Volcanoes are formed===
'''Volcanoes''' are formed along 2 different types of [[Tectonic Plate Margin|tectonic plate margin]]; [[Destructive Plate Margin]]s and [[Constructive Plate Margin]]s.

At [[Destructive Plate Margin]]s more [[dense]] [[Oceanic Plate|oceanic plate]] moves under the less [[dense]] [[Continental Plate|continental plate]]. As this happens the [[Oceanic Plate|oceanic plate]] is melted and a lot of [[magma]] forms in a large pool. This [[magma]] then rises towards the surface of the [[crust]] through cracks in the [[crust]] called [[vents]].

Holly Simms: /* About Tsunamis */

==Key Stage 4==
===Meaning===
A '''tsunami''' is a giant [[wave]] caused by an [[earthquake]] or [[landslide]] under the [[Sea Bed|sea bed]].

===About Tsunamis===
[[Earthquake]]s under the [[Sea Bed|sea bed]] cause a large volume of water to be displaced due to a large output of [[energy]]. This [[energy]] creates a large wave that travels through the water at up too 500kmph.
When tsunamis reach the [[coast]] [[friction]] builds between the much more [[shallow]] [[Sea Bed|sea bed]] and the high speed energy of the wave as there is less water for the [[energy]] to travel through. This friction causes the wave the to slow down as friction builds and therefore as it slows down the height of the wave increases. After this increase in height Tsunamis can reach up to 100ft as they come in contact with land.
When they reach land Tsunamis flood the area [[local]] to the [[coast]] and can cause large amounts are destruction including damage to people's [[property]], damage to the [[local]] [[environment]], and loss of life.

===About Tsunamis===
[[Earthquake]]s under the [[Sea Bed|sea bed]] cause a large volume of water to be displaced due to a large output of [[energy]]. This water then creates a large wave that travels across the water at up too 500km/h and can reach a height of up to 30m.
