The scientific use that is applied to Google Earth in the matter of geography and geology every day is more interesting, although we from the cadastral point of view we criticize a lot its accuracy for our selfish ends.
Some time ago I was talking about the animated map that exists of tectonic evolution through the theory of continental drift. The United States Geological Survey (USGS) in conjunction with Google has created a Cape in which you can see the different tectonic plates that make up the lithosphere of our planet. Too educational for a post, but I will try to keep it as simple as 700 words of the patience of my visitors and inspired by a new blog that I discovered today called todocartografía.
1. The plates
At least 15 boards are recognized:
| In our Spanish-speaking environment these are related to us:
North America, from Guatemala to the pole is the North American plate, coinciding in the Pacific with the plate of the Pacific and the small plate of Juan de Fuca Central America, is the Caribbean plate and the Cocos plate, which is towards the Pacific Ocean South America, there are the South American, Scottish and Nazca plates. Very south of Chile there is some contact with the Antarctic plate. Spain is on the Eurasian plate, sticks with the African plate. |
|
So that in our Hispanic environment, we have relationship with 11 of the 15 plates. The following map shows these layers painted in the style of the school.
2. The displacement
The flow of the boiling lava under the surface causes the plates to have a displacement that is approximately 2.5 cm per year, (the speed at which the nails grow) arrows that indicate this direction are shown on the map. This separation or approach is not much, however it is considerable if we think how much a point has moved in 30 years, it would be 75 centimeters. If we think of a point in Mexico, which moves 75 centimeters to the west and the Greenwich meridian that moves in the opposite direction would be 1.50 meters. The point is that the plates move, but the mesh that the latitudes and longitudes make up does not change; which means that a point is moving relative to its coordinate system.
As a consequence, the same point, measured under the same conditions, within 30 years would be displaced 75 centimeters. The Google Earth map shows the displacement and direction of the plates in different areas.
This is one of the reasons why the topographic survey is tied with control points, which maintain this relative reference for the subsequent cadastral maintenance with respect to the geodetic vertices. Finally we realize that the ultra precision of our gps are quite relative to the exaggerated attention that we lend them.
3. Geological faults
The rose or displacement between these plates is what has formed the mountain ranges, it is also what causes earthquakes or volcanic activity. At least three relationships between the plates are considered:
- Convergents (Collide with each other)
- Divergent (Separating)
- Transformers (They slide together)
Meanwhile, the boundaries between the plates can be:
- Constructive
- Destructive
- Conservative
The Google map shows this situation in different colors.
Also the map includes a layer of seismic movements, it is assumed in real time, showing the magnitude and date themed.
The best beneficiaries of this type of Google Earth functionalities are the educators, mainly those who teach Geography, Social Studies and Geology classes ... undoubtedly, Google Earth changed our way of seeing the sphere.

What a horror to see that many a dictionary would be the best thing they could ask for for Christmas.
Greetings from Chile, very good information indeed.
I just need to know what moves they do
each of the plates
Nose
they are not worthy of naaa lo perkinazos ctm .l.
It depends. With h and with c, if we use the dictionary ...
Greetings to Chile
I love doing poop and you
very good
I want to know the EUROASIATICA fault if it is in motion since it fails corresponds to the one that is moving in Italy!
Thank you
In what direction and until the region moves the Eurasian plaque
this is not what I want
I need the map of tectonic plates
what is the rose movement
I need to know what are the characteristics of the Pacific tectonic plate
poorr ifs can tell me the characteristics of the plates
African Board
Antarctic plate
Arabic plate
Australian Board
Coconut Plate
Caribbean Plate
Scottish Board (Scotia)
Eurasian plate
Philippine Plate
Indo-Australian Plate
Plate Juan de Fuca
Nazca Plate
Pacific Plate
American plate
South American Plate
or darmeee the page in k you can go out
Cuuuuuuuuuuuuoooooooooooo
it's no use
hello that's nothing important
I need to know the surface of all tectonic plates
porfavorrrrrrrrrrr
I think that the tectonic plates are certainly displaced by the expulsion of materials on the seabed but the material that is being expelled from the heart of the earth is the one that we have under the feet which influences the position of the continents with respect to the sea and this causes tsunamis and sunamis it is true that the melting of the polar cones affects the height of the seas but the above mentioned situation is happening since the same force of gravity affects the surface of the continents I say this for the holes found in Guatemala and other parts of the world and the alarming number of tsunamis, earthquakes and other events worldwide.
at what time as ??
HOW DOES EARTH GROUND PRODUCE? TENBLOR AND SEISM IS THE SAME?
in what suits me this page is very good since in it you can get and also give opinions on any subject
Hello! Hey, by chance, could you tell me what the features of the following boards are:
- Pacific Plate
- North American Plate
- Eurasian plate
- Coconut plate
- Caribbean plate
- Nazca plate
- Antarctic Plate
- South American Plate
- African Plate
- Indo-Australian plate ???
Please, I need the features… !! I would appreciate it very much !!
NOTE: Do not send me the page of wikipedia because I already have it, but if they have another page please tell me !! or if they know the answer they tell me xDDD
I would like to know the characteristics, coordinates, structural state and location ... thank you very much ...
Hehe, I hope it does not give him an earthquake in the diaphragm.
I am very frightened yesterday to my grandfather, the doctor I put a plate, and I do not know that plate will be the one of coconut or the one of the bocota.
Check out this to see if it serves you
I need the map of the movement of the tectonic plates ......... .. help me ......... pro.
my daughter should do a work on how the tectonic plates of spain will be inside 1000, 10.000 and 100.000 years.
I am not an expert on this and I think you will help me. Thank you
truly sometimes ignores so many things but thanks to you. Today I learned so many things. I like to learn and keep visiting the page every time q. have doubts about any particular.
I need to know what was the last earthquake due to plate movement?
IT IS VERY INTERESTING YOUR INFORMATION AND WITH THE PICTURES I REMAIN MUCH MORE CLEAR.
IT IS GOOD TO HAVE A SITE WITH ALL PRESENT INFORMATION
many thanks was a very important task
with desimas for the pruba to which I do not study much
(nothing)
well, that's great
uuuuuuuuuuuuuuuuuuuuuuuuuu !!! I rre served me all thank you very much ... kisses mua
this does not serve much need all the movements of the plates but it is for tomorrow :(
hello it served me for the task thanks…. where can i find about earthquakes and volcanism
this page seems very interesting to me
Here is a map of the tectonic plates

I need the map of the movement of the tectonic plates ......... .. help me ......... pro.
In what direction do the euroasiatic and pacific plates move, and the Euro-Asiatic and Indo-Australian plates?
It is recognized not 12 but 15 plates and these are:
African Board
Antarctic plate
Arabic plate
Australian Board
Coconut Plate
Caribbean Plate
Scottish Board (Scotia)
Eurasian plate
Philippine Plate
Indo-Australian Plate
Plate Juan de Fuca
Nazca Plate
Pacific Plate
American plate
South American Plate
And also which are the 12 main plates in which the lithosphere is divided?
I need to know: in which directions do the euroasiatic and pacific plates move? and the indoaustralian Euroasiatica?
wauuuu !!!!!!! =) me rre served for the task =) haha
bessooss
The plates of Chile are:
Nazca
Antarctica
Scottish
Here you can see a photo
