WELCOME!
This blog offers an exceptional discovery analizis the layers of our planet from the Earth's crust to the depths of hot mantle into the secret core of the planet. Also offers a look at what man kind will probably never reach, the more alien and hostile to the rocks, lava, and minerals below the earth's crust. While the crust is approximately 20 to 30 km deep in most places, humans have never traveled further, even so, research continues to prove impossible.We can say that the interior of the Earth has many aspects that makes it a unique theme.Hopefully you people like this. Thanks!
Plate Tectonics.
Plate Tectonics is an extraordinary concept. Scientists have a theory that Millions of years ago, the whole planet earth was one giant piece of land called "Pangaea". Over Millions of years, magma has been pushing and pushing the continents apart, so now we are seven continents.They think the theory may be real because how is it possible that the animals on Africa, are found in South America? The Tectonic Plates are composed of two types of lithosphere which are, thicker continental and thin oceanic.Basically there are there types of plate boundaries.
They are, Transform Boundaries(conservative)occur when the two plates slide. There are Divergent Boundaries, which happen when two plates slide apart from each other, and there is convergent boundaries, they happen when two plates slide towards each other commonly forming a subduction zone. There are so many amazing things about plate tectonics and scientists have a long way to go to find out more great things!!
