Interesting layout.
Good information. Wiki is not a reliable source of information just so you know in the future.

_An example of " geohazards " would be , many factors combined to make BC vulnerable to geohazards . Theis factots being the substantial amount of rain and snow in Canada , geological makeup , and lots of sediments layed down by glaciers . oh and last but not least BC is located in an active tectonic region .

_Western and southwest BC experiences more then 300 earthquakes a year . Most are so small that they only registered on a seismograph . But sadly large earthquakes have happened before and will happen again .

_Features of the land scape like soils quality , salmon spawing areas , river deltas , and hot springs have influenced the patters of people that have taken over throughout history.

_plate tectonics explain BCs geological processes , and thies processes literally shaped the landscape , the places that you know of , the places you walk on , and visit .

_The way a modern seismograph works is that it contains three electronic seismometers to record north-east-west-south and up and down motions .
_Seismic data from many seismograph are uploaded to computers , the information determines strength and location of the earthquake .

_the way people measured Earthquakes is by using a seismograph , which is an instrument that measures and records seismic waves , or another way of saying it " ground vibrations ".

EARTHQUAKE (Types of Seismic Waves, Earthquake Terminologies, and 4 Basic Types of  Fault)

_The l wave is the slowest out of all the waves , however it still causes the most damage . L waves cause rock particles to both move up and down and side by side . Unlike the other waves , l wavs can travel along the surface of Earth .

sources : notes , text book

# data[].attributes.body
_A secondary wave moves slower then the p wave . Secondary waves cause rock particles to move up and down , however unlike the p wave , s waves can only travel through solids .

# data[].attributes.body
_The p wave moves fastest out of all the waves , it is also the first one that is detected in an earthquake . It causes rock particles to move forwards and backwards , it can also travel through both liquid and solid .

slab pulls is that part of the motion is partly driven by weight of cold , dense plates sinking into the mantle at oceanic trenches . This force and slab suction account for almost all of the force driving plate tectonics .

_Mantle convection is a very slow creeping motion of Earths solid silicate mantle caused by convection currents carrying heat from the interior to the plates surface .

sources : wiki , geol705.sitehost.iu.edu

# data[].attributes.body
the mantle is right below the core , and in areas that are hotter it rises upwards , whereas in areas that are cooler it sinks down . When that happens in convection cells in the mantle , and produces horizontal motion of mantle material close to Earths surface .

sources : text book , notes

_Tectonic plates move slowly and floats on the asthenosphere, a layer that is made up of extremely hot material that is sort of like plastic ( every couple of  years it moves by 2 meters so the changes were to slow to recognize back then )

sources : notes , text book , wiki

# data[].attributes.body
_Transform plate boundaries is where two tectonic plates slide "past" each other horizontally , again earthquakes are really common . ( just like all the other plate " mantle convection " is what drives tectonic plates movement )

sources : text book

# data[].attributes.body
volcanoes and mountains form at theis boundaries , earthquakes are also really common .

sources : text book

# data[].attributes.body
_Its when two tectonic plates collide , how it works is when the denser crust eventually goes below less-denser crust in the process called subduction and cause a "deep sea trenches" to form .

# data[].attributes.body
Divergent plate boundaries are where plate tectonics" move apart " and create new oceanic crust .
_Can also occur in the middle of continental ( continental rifting )

_When the plates start to separate molten rocks start to rise to the sea floor , which then build up enormous volcanic eruptions of basalt , which could effect the shape of a ridge . If the spreading is slow then it will cause irregular topography , and if the spreading is fast then it will cause wider profiles and gentle slopes

# data[].attributes.body
_The mid-ocean ridges system is like a range of underwater volcanoes that go around the globe , stretching around 65,000km . Most mid-ocean ridges are found along " divergent plate boundaries " , where new ocean floor is created .

# data[].attributes.body
_Slab pulls : now as for slab pulls , slab pulls is like pulling of tectonic plate because of gravity and subduction .
_ When the heading edge of a subduction plate sinks it pulls the rest of the plate with it at a convergent plate boundary , gravity and convection is also involved in the process

# data[].attributes.body
_Sea floor spreading
_Ridge push
_Slab pulls
_Ridge push :  so how it works is that new material pushes older material aside causing tectonic plates to end up moving apart rising material spread out as it reaches the upper mantle _ It also causes the lithosphere to lift and push tectonic plates apart at a divergent plate boundaries

# data[].attributes.body
.Suggest that ocean floor is younger the closer it is to mid-ocean ridges , so the closer ocean rocks are to mid-ocean ridges the younger they are , the farther away they are the older

# data[].attributes.body
_Making new rocks on ocean floor
.Ocean floor near mid-ocean ridges are  younger then ocean floors farther away from ridges
.Sediment gets thicker as you move farther away  from the mid-ocean ridges

just like the mantle the core also has layers , the " outer core " is the only layer that is liquid ( metal liquid and iron ) . As for the" inner core " it is the deepest , hottest layer (more then 5000 degrees ) it is also a solid because the core material is under extreme  pressure . The inner core has a radius of 1,220 km which is about 20% of Earths radius . The inner core is believed to be composed of an iron - nickel alloy with some other elements .

mantle is a bit different it kind of has layers ( upper mantle , lower mantle ) . the upper mantle is solid the bottom part is made of a rock that  is soft and taffy ( can flow slowly ). As for the upper mantle it is made of a much denser and solid material then the upper mantle .

# data[].attributes.body
first starting with the thinnest layer of the Earth " crust",  crust is like a thin shell on the outside  of Earth , accounting for less then 1% of Earths volume . Earths crust is actually made of many elements like oxygen( 46.6%) , silicon ( 27.7%), aluminum ( 8.1%), iron ( 5%) , sodium( 2.8%) and so on.

as for climate change an example would be , and island in the Arctic ocean contains fossils of tropical plants  and ect . But obviously nobody believed him until another scientist "Harry Hess " helped by giving more proof to his theory almost 50 years later by using evidence of sea floor spreading to explain what moved continents.

# data[].attributes.body
first starting with fossil information , for example  there were many fossils that are originally found in hot places , but were found frozen in in cold places . for example Mesosaurs  which is supposed to originally  be found in south America and Africa during the Permian  period , and now it could be found in many different continents , like not just south America but also Eastern south America .

In 1912 Alfred wegeuer noticed that the continents are like puzzle pieces and that they fit , so he started looking for more evidence to prove his theory like rocks , climate , and fossil information.
