Question: Identify and give the composition of the layer responsible for the earth's gravity?

Earth's gravity is primarily a result of its mass, with the core playing the most significant role due to its high density. The layer mainly responsible for Earth's gravity is the inner core and outer core, which are composed largely of iron (Fe) and nickel (Ni).

Composition of the Core:

Inner Core: A solid sphere of iron and nickel, with extreme density and pressure.

Outer Core: A liquid layer surrounding the inner core, composed of molten iron and nickel.

Since gravity is directly related to mass, Earth's core contributes the most to its gravitational pull due to its dense, heavy elements.
