EVERYDAY SCIENCE

Detailed explanation-1: -The dense, hot inner core (yellow), the molten outer core (orange), the mantle (red), and the thin crust (brown), which supports all life in the known universe. Earth’s core is the very hot, very dense center of our planet. The ball-shaped core lies beneath the cool, brittle crust and the mostly solid mantle.

Detailed explanation-2: -The liquid part of the Earth’s interior is called the outer core. The outer core surrounds the innermost layer, the solid inner core in the very center of the planet. Surrounding the liquid outer core is the viscous mantle and then the outermost layer, the crust.

Detailed explanation-3: -The inner core is at the center of the Earth because it is the densest, made of solid iron and nickel.

Detailed explanation-4: -The outer core is the liquid largely iron layer of the earth that lies below the mantle. Geologists have confirmed that the outer core is liquid due to seismic surveys of Earth’s interior.

Detailed explanation-5: -The core of the Earth is made up mainly of iron, in an outer liquid layer and an inner solid layer.
