The planet is divided into the crust, the mantle, and the core. This layer is broken into tectonic plates that float and move on the layer beneath it.
Magma Reservoirs: Locating the Molten Rock Beneath Our Feet
The Role of Heat and Pressure. The Structure of the Earth's Interior To pinpoint where magma is located, one must first understand the layered structure of the Earth.
Tectonic Setting Typical Depth to Magma Example Location Mid-Ocean Ridge 5 – 20 km Mid-Atlantic Ridge Subduction Zone 100 – 150 km Cascadia Subduction Zone Hotspot 50 – 200 km Hawaii Continental Rift 20 – 80 km East African Rift Magma Chambers and Storage Rather than being a continuous river of molten rock, magma often accumulates in discrete pockets known as magma chambers. Understanding its location requires looking beyond the surface and into the dynamic interior of our planet.

This molten rock is not a uniform layer but exists in distinct zones, most notably within the asthenosphere, where temperatures and pressures allow for partial melting of rock. The Lithosphere and Asthenosphere The rigid, outermost layer of the Earth, including the crust and the uppermost part of the mantle, is called the lithosphere.
