5 Brilliant Layers Of, Earth Lesson Plan Middle School Photos - The middle is at the middle of the earth. It's miles break up up into the outer center and the internal center. The inner core is solid and composed of an iron-nickel alloy. It's far very hot with a temperature believed to be approximately 5,500°c. The outer core is likewise made of iron and nickel and surrounds the inner middle. The outer core is beneath much less pressure than the inner center and is in a liquid country.

The surface of the earth is break up up into portions referred to as tectonic plates. The road in which plates meet is known as a boundary, or a fault line. The largest of all of the tectonic plates is the pacific plate which sits below the pacific ocean and has a place of 103 million km2. These plates are continuously transferring, though no longer in no time; they best flow a few centimeters every year. They move due to the movement of magma inside the mantle; the plates “flow” on pinnacle of the mantle. Every so often those plates get caught and don’t pass past each different. This shops up elastic capacity potential electricity and whilst the plates slip, this power is released as seismic waves. If the strength launched is huge sufficient, those seismic waves may be very huge and are called earthquakes.
