Aku Ingin Tahu Sains Bencana Alam (Indonesian Edition)

Synopsis: “Our Earth has many layers just like layer cake (kue lapis). The outermost layer of earth is called the Earth’s crust. We live on this layer because it’s made from solid rocks. The layer below the earth’s crust is called the earth’s coat. Earth’s coat contains minerals like iron and magnesium and also magma (molten rock) with extremely hot temperature. Under the earth’s coat, there’s still earth’s core layer, which is inside and outside the earth’s core. The outside of the core consists of iron elements which is in liquid phase like syrup whereas the inside one consists of solid iron. The deeper the earth layer, the higher is the temperature. Earthquake itself is a vibration which happened inside the soil caused by earth’s plate movement. Strong vibration can cause an earthquake which can cause massive damages on building, highway, bridge and other buildings and may also result in fatalities."
