Deeper inside the Earth, beneath the crust, lies the mantle.
Understanding Earth's Layers
To better understand what's deeper inside our planet, it's helpful to know the basic structure of the Earth. It is composed of several layers, similar to an onion. From the surface moving inwards, these layers are:
- The Crust: This is the outermost solid layer, and where we live.
- The Mantle: This is the thickest layer beneath the crust, according to the reference it makes up 84% of the Earth's volume.
- The Outer Core: This is a liquid layer made mostly of iron and nickel.
- The Inner Core: This is a solid sphere at the very center of the Earth, also mostly iron and nickel.
The Mantle: Deeper than the Crust
Based on the provided reference, the mantle is located directly beneath the Earth’s crust. It is composed of hot rock. The reference notes:
- The upper mantle's rocks are extremely hot.
- If cooled, the rocks of the upper mantle would appear as a speckly olive green due to the presence of the mineral olivine (also known as peridot).
Depth Progression
So, when we talk about "deeper inside the Earth," we're talking about moving through these layers. Here's a simple progression:
- Surface: The crust.
- Deeper: The mantle.
- Even Deeper: The outer core.
- The Deepest: The inner core.
Therefore, the mantle is indeed deeper than the crust, and is a significant portion of our planet.
