2019 Science Term 1

Layers Of The Earth

This Term in science we learnt about the layers of the earth. As part of our project we had to find out what the different layers are and what makes that layer perfect. The layers is Crust, Mantle, Outer Core, and Inner Core. We also found out what other layers there are in the earth that is important like the lithosphere and the asthenosphere. There are also two other crust called the Oceanic Crust and Continental Crust.

Plate Tectonics

Through this term we also learnt about the Plate Tectonics. We found that Plate Tectonics are the reason why the Pangaea which was one big continent was divide because of the moving of the Tectonic Plates. The three Plate Tectonic movements are Divergent, Convergent and Transform which do different things,the Divergent Plates is when two plates move away from each other, Convergent Plates is when two plates come in together and move in, and finally Transform Plates is when the two plates motion is predominantly horizontal.

Volcanoes

Our class also learnt about volcanoes. We also learnt about the different things that made the volcano erupt. The parts of the volcanoes is the Vent, Ash Cloud, Crater, Parasitic Cone, Throat, Lava, Lava Flow, Conduit our people call it the pipe, Ash, the sill and the Magma Reservoir. These are the eleven things that make a volcano erupt.

Earthquakes

And finally we learnt about earthquakes. I found out that Earthquakes are connected to the Tectonic Plates. I found this out by study the movement of the Earth and saw that it was moving like the Tectonic Plate boundary called Transform.
