This term has been cluttered, but I have tried my best to be a hardworking student. I finished my work most of the time and on the other hand I was talking or I was not on task. I learnt about things related to the earth which was interesting, like Earth Layers, Volcanoes and Earthquakes.
Personally you can think of the Earth as being made of different numerals, sort of like a apple, but a apple only has three layers, the skin represents the crust, the flesh represents the mantle and the core stays as the core. But so the four main layers of the earth are Crust, Mantle, Outer core and Inner core.
Image of the Layers of the Earth.
The Crust is the outer layer of the earth, which is 3-5 miles (8 kilometres) under the oceans (oceanic crust) and about 25 miles (32 kilometres) thick under the continents (continental crust). The Mantle is a layer in between the crust and the core, it is 2,900 kilometres (1,802 miles) thick, and makes up a whopping 84% of the earth's total volume. The Outer core is the only liquid layer, which is 2,200 km thick. The Inner core is right on the inside, which is as hot as the sun's surface but not as hot as the inside of the sun because there's pressure being put on it by the layers on top of it. This layer is 1,250 km thick.
In the earth there are 12 tectonic plates, but there are 7 major plates, called African, Antarctic, Eurasian plate, Indo-Australian plate, North American plate, Pacific plate, and South American plate. There are 3 different types of boundaries: Divergent, Convergent, Transform.
Divergent- Divergent boundary is when the plates move away from each other.
Convergent- This boundary is when the plates move towards each other.
Transform - This is when the plates slide past each other.
This is what I learnt in Science this term. THE END!!
