The mantle is the layer that contains rocks.
Understanding the Earth's Layers
To understand which layer contains rocks, let's briefly review the Earth's structure:
- The Earth is primarily divided into three layers: the crust, the mantle, and the core.
- Each layer has different compositions and properties.
- The crust is the outermost solid layer.
- The mantle is beneath the crust and is a thick layer of mostly solid rock.
- The core is the innermost layer and has a liquid outer part and a solid inner part.
The Mantle: A Layer of Solid Rock
Based on the provided reference, here is more information about the mantle:
- The mantle is located below the Earth's crust.
- It extends up to 2900 kilometers in thickness.
- The mantle is composed of hot, dense, iron and magnesium-rich solid rock.
- The uppermost part of the mantle, along with the crust, makes up the lithosphere.
- The lithosphere is fragmented into various tectonic plates.
Key Points:
- The reference confirms that the mantle is primarily made up of rock.
- The rocks in the mantle are described as being iron and magnesium-rich.
- The mantle is not just a molten liquid; it has solid components.
- The rocks within the mantle, although incredibly hot, are considered solid rather than molten liquid.
Therefore, the mantle is the Earth layer with rocks.
