The Earth’s crust is made up of a number of tectonic plates. These plates are constantly moving, and their movement is responsible for many of the Earth’s geological features, including earthquakes, volcanoes, and mountain ranges.
But what is the layer of the Earth that tectonic plates ride on top of? The answer is the asthenosphere.

The Asthenosphere
The asthenosphere is a layer of the Earth’s mantle that is located below the lithosphere. It is a semi-solid layer that is made up of hot, flowing rock. The asthenosphere is about 100 to 200 kilometers thick.
The asthenosphere is heated by the Earth’s core. This heat causes the rock in the asthenosphere to flow. The flow of the asthenosphere is what drives the movement of tectonic plates.
Tectonic Plates
Tectonic plates are large, rigid slabs of the Earth’s crust. They are made up of the crust and the upper part of the mantle. Tectonic plates are constantly moving, and their movement is caused by the flow of the asthenosphere.
Tectonic plates move in a number of different ways. They can move towards each other, away from each other, or slide past each other. The movement of tectonic plates is responsible for many of the Earth’s geological features, including earthquakes, volcanoes, and mountain ranges.
The Relationship Between Tectonic Plates and the Asthenosphere
Tectonic plates ride on top of the asthenosphere. The asthenosphere is a semi-solid layer that is made up of hot, flowing rock. The weight of the tectonic plates causes the asthenosphere to flow. This flow of the asthenosphere is what drives the movement of tectonic plates.
Conclusion
The answer to the question of which layer of the Earth tectonic plates ride on top of is the asthenosphere. The asthenosphere is a layer of the Earth’s mantle that is located below the lithosphere. It is a semi-solid layer that is made up of hot, flowing rock. Tectonic plates ride on top of the asthenosphere. The movement of the asthenosphere is what drives the movement of tectonic plates.
FAQ
Q: What is the difference between the lithosphere and the asthenosphere?
A: The lithosphere is the rigid outer layer of the Earth. It is made up of the crust and the upper part of the mantle. The asthenosphere is a layer of the mantle that is located below the lithosphere. It is a semi-solid layer that is made up of hot, flowing rock.
Q: What is the thickness of the asthenosphere?
A: The asthenosphere is about 100 to 200 kilometers thick.
Q: What causes the asthenosphere to flow?
A: The asthenosphere is heated by the Earth’s core. This heat causes the rock in the asthenosphere to flow.
Q: What is the relationship between the movement of tectonic plates and the asthenosphere?
A: The movement of tectonic plates is caused by the flow of the asthenosphere. The weight of the tectonic plates causes the asthenosphere to flow. This flow of the asthenosphere is what drives the movement of tectonic plates.
