T maya_sangala https://padlet.com/maya_sangala/4iw8eay2t3bk/wish/171428425 North and South America have joined, Africa and Eurasia are divided. This, folks, is our earth]]> 2017-05-12 08:05:43 UTC https://padlet.com/maya_sangala/4iw8eay2t3bk/wish/171428425 Permian Stage maya_sangala https://padlet.com/maya_sangala/4iw8eay2t3bk/wish/171428429 Millions of years ago, all land was clumped together into one extra large continent, called Pangea. The next stages depict the ways in which this continent divided and spread due to the movement of tectonic plates.]]> 2017-05-12 08:05:43 UTC https://padlet.com/maya_sangala/4iw8eay2t3bk/wish/171428429 Cretaceous Stage maya_sangala https://padlet.com/maya_sangala/4iw8eay2t3bk/wish/171428430 This is the stage closest to our own. You can clearly indenting the different structures we know today. Note however how north and South America aren't connected.]]> 2017-05-12 08:05:43 UTC https://padlet.com/maya_sangala/4iw8eay2t3bk/wish/171428430 Triassic Stage maya_sangala https://padlet.com/maya_sangala/4iw8eay2t3bk/wish/171428431 This is the second stage of the formation of land as we know it today. Here, Pangea divided into two supercontinents: Laurasia in the north and Gondawa in the south. ]]> 2017-05-12 08:05:43 UTC https://padlet.com/maya_sangala/4iw8eay2t3bk/wish/171428431 The rift is a narrow zone that is a developing divergent tectonic plate boundary,in which the African plate is in the process of splitting into two tectonic plates,called the Somali plates and the nabian plates at the rate of 6-7mm annually as extension continues ,lithosphere will occur within 0 million years, the somaliplate will bfreak off,and a new ocean basin will form maya_sangala https://padlet.com/maya_sangala/4iw8eay2t3bk/wish/171428432 2017-05-12 08:05:43 UTC https://padlet.com/maya_sangala/4iw8eay2t3bk/wish/171428432 maya_sangala https://padlet.com/maya_sangala/4iw8eay2t3bk/wish/171428433 A continental carton:is an old old and stable part of the continental lithosphere,where the lithosphere consists of the earth tw top most layer,the crust and the upper most mantle.
Ocean basin:This are areas found under the sea.They are relatively inactive areas where deposits of sediment slowly collect and active areas where tectonic plates meet.
Volcanic arc:volcanic arts result from the subduction of an oceanic tectonic plate under another tectonic plate, and often parallel an oceanic trench.

It is surrounded by several layers of magma. The actual crust on which we live  is tiny and superthin  compared to the rest of the earth.]]> 2017-05-12 08:05:43 UTC https://padlet.com/maya_sangala/4iw8eay2t3bk/wish/171428435 Convergent Boundaries on land maya_sangala https://padlet.com/maya_sangala/4iw8eay2t3bk/wish/171428436 This is the same as the previous post, only that as mentioned, it causes mountains and earthquakes. One sample of mountains is the Himalaya Range, and an earthquake: the one in Nepal.The Washington-Oregon coastline of the United States is an example of convergent boundaries on land]]> 2017-05-12 08:05:43 UTC https://padlet.com/maya_sangala/4iw8eay2t3bk/wish/171428436 Convergent Boundary on sea and land maya_sangala https://padlet.com/maya_sangala/4iw8eay2t3bk/wish/171428437 This is sometimes called the 'destructive boundary' as  is the causer of earthquakes. Here two plates collide against each other. One slips under the other and then it finally collides back. This image is of sea,  and one thing convergent boundaries can cause in the sea are volcanoes.

This  can cause rifts that can eventually cause Rift Valleys.]]> 2017-05-12 08:05:43 UTC https://padlet.com/maya_sangala/4iw8eay2t3bk/wish/171428439 Transform maya_sangala https://padlet.com/maya_sangala/4iw8eay2t3bk/wish/171428440 Transform boundaries are places where plates slide sideways past each other. Many transform boundaries are found on the sea floor, where they connect segments of diverging mid-ocean ridges. Their sliding motion causes lots of earthquakes. The strongest and most famous earthquake along the San Andreas fault hit San Francisco in 1906. Many buildings were shaken to pieces by the quake, and much of the rest of the city was destroyed by the fires that followed.]]> 2017-05-12 08:05:43 UTC https://padlet.com/maya_sangala/4iw8eay2t3bk/wish/171428440 Plate Tectonics maya_sangala https://padlet.com/maya_sangala/4iw8eay2t3bk/wish/171428441 Plate onics explains the features and movement of Earth's surface in the present and the past.
Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. The plates act like a hard and rigid shell compared to Earth's mantle. This strong outer layer is called the lithosphere.]]> 2017-05-12 08:05:43 UTC https://padlet.com/maya_sangala/4iw8eay2t3bk/wish/171428441 Jurassic Stage laura_reumont https://padlet.com/maya_sangala/4iw8eay2t3bk/wish/171430752  The time of the dinosaurs!
