earth structure

• the earth's crust is made up of tectonic plates
• The Earth's inner core is in the center and is the hottest part of the Earth
• The inner core is solid and made up of iron and nickel with temperatures of up to 5000°C
• The outer core is the layer surrounding the inner core
• The outer core is a liquid layer, also made up of iron and nickel
• The outer core is extremely hot, with temperatures similar to the inner core
• The mantle is the widest section of the Earth with a diameter of approximately 2,900 km
• The mantle is made up of semi-molten rock called magma
• In the upper parts of the mantle, the rock is hard, but lower down, the rock is soft and beginning to melt
• The crust is the outer layer of the Earth
• The crust is a thin layer between 60 km thick
• The crust is the solid rock layer upon which we live
