Explanation:
Earth's Lithosphere:
- The Earth's lithosphere is composed of both the crust (the outermost layer) and the upper mantle.
- This layer is relatively rigid and brittle, and it is broken up into tectonic plates that float on the semi-fluid asthenosphere below.
Asthenosphere:
- The asthenosphere is a semi-fluid layer located beneath the rigid lithosphere.
- Unlike the lithosphere, the asthenosphere is capable of flow over long periods of time.
Movement of Tectonic Plates:
- The movement of tectonic plates is indeed driven by convection currents in the mantle.
- Heat from the Earth's core causes convection currents in the mantle, which in turn cause the movement of the tectonic plates.
Therefore, out of the three statements given, only the second and third statements are correct. The lithosphere includes the crust and the upper mantle, and the movement of tectonic plates is driven by convection currents in the mantle. The first statement is incorrect in stating that the asthenosphere is rigid, as it is actually semi-fluid.

- Statement 1 is correct: The lithosphere includes the crust and the uppermost part of the mantle.
- Statement 2 is incorrect: The asthenosphere is not rigid; it is a semi-fluid layer beneath the lithosphere.
- Statement 3 is correct: The movement of tectonic plates is driven by convection currents in the mantle.
