the earths structure
The earth is made up of 4 layers. The Earth has a layered structure made up of the core,mantle,crust and the lithosphere. The crust and the upper part of the mantle are broken up into large pieces called tectonic plates. These move slowly over the mantle.
Volcanoes occur when molten rock pushes up through weaknesses in the crust. The molten rock cools and solidifies to form igneous rocks, such as basalt, gabbro rhyolite and granite.

what we learned in the lesson?
CRUST: The crust is the layer you live on. It is a thin skin of rock around the earth,like a skin of an apple.
MANTLE: It forms about half of the earth it is made up of heavier rock. The rock below it is hot and soft like soft toffee. it is very runny in places
CORE: It is mainly noth mixed with a little nickel. The outer core is liquid the inner core is solid.
