What do tectonic plates float on?
Understand the Problem
The question is asking about the medium on which tectonic plates float. This relates to geology and plate tectonics, suggesting that the answer involves concepts like the Earth's mantle and asthenosphere.
Answer
Asthenosphere
Tectonic plates float on the asthenosphere, which is the upper layer of Earth's mantle.
Answer for screen readers
Tectonic plates float on the asthenosphere, which is the upper layer of Earth's mantle.
More Information
The asthenosphere's semi-fluid nature allows the solid tectonic plates to move and shift on top of it.
