Convection Currents

Harry Howe: /* Convection Currents */

===Meaning===
Convection

‘’’Convection currents’’’ are powered by changes in [[Temperature|temperature]]. As [[Magma|magma]] near the core of the earth heats up it rises towards the earth’s [[Crust|crust]]. When the [[Magma|magma]] that has risen reaches the plates it becomes [[Displacement|displaced]] and moves horizontally. As the [[Magma|magma]] has been near the surface it starts to cool. The colder magma then returns to the core of the earth, finishing a circular motioned cycle known as a ‘’’convection current’’’.
These ‘’’Convection Currents’’’ are responsible for all the [[Tectonic Plate|plate]] movement that occurs in [[Tectonic Plate Margin|plate margins]].

Constructive Plate Margin

Harry Howe: /* About Constructive Plate Margins */

==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 [[Convection Currents|convection currents]] become disrupted - allowing [[magma]] to rise through the gap. This process 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]].

Harry Howe: /* 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 as a result of [[tectonic plate|plate]] movement. 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 Plate|plates]] move.

[[Destructive Plate Margin]]s typically occur between a [[Continental Plate|continental plate]] and [[Oceanic Plate|oceanic plate]]. Upon collision, the denser [[Oceanic Plate|oceanic plate]] is forced under the lighter [[Continental Plate|continental plate]] in a process known as [[Subduction|subduction]]. There is a huge build-up of [[friction]] between the two plates as this happens, until the [[force]] becomes so great the plates no longer move. 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 the plates grind past each other causing a build-up of [[friction]]. As tension builds the plates 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.

Earthquake

2020-09-20T13:53:43Z

Harry Howe: /* Meaning */

==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 as a result of [[(tectonic) plate]] movement. 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 Plate|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.
