Which is the innermost layer of the Earth?(1 point) Responses crust crust lithosphere lithosphere inner core inner core mesosphere
The innermost layer of the Earth is the inner core.
The innermost layer of the Earth is the inner core.
The innermost layer of the Earth is the inner core. To arrive at this answer, let's break down the layers of the Earth:
1. Crust: This is the Earth's outermost layer, composed of solid rock that forms both the continents and the ocean floors.
2. Lithosphere: This layer includes the crust and a portion of the upper mantle. The lithosphere is divided into tectonic plates that move over the semi-fluid asthenosphere below.
3. Mesosphere: Also known as the lower mantle, this layer is located beneath the lithosphere. It consists of solid rock but is more fluid than the lithosphere.
4. Outer Core: This layer is a liquid region, composed mainly of molten iron and nickel, which surrounds the inner core.
5. Inner Core: The innermost layer of the Earth is the inner core. It is solid and primarily composed of iron and nickel.
Therefore, the innermost layer of the Earth is the inner core.
