Explanation:

Option 1: This statement is correct. Tectonic plates are indeed composed of both oceanic lithosphere (which is thinner and denser) and continental lithosphere (which is thicker and less dense). This is because the Earth`s lithosphere is comprised of both oceanic and continental crust.

Option 2: This statement is also correct. Tectonic plates are able to move because the Earth`s lithosphere is stronger and more rigid compared to the underlying asthenosphere, which is partially molten and less rigid. The strength of the lithosphere allows for the movement of tectonic plates.

Option 3: This statement is correct. The Earth`s lithosphere is indeed broken up into tectonic plates. These plates are like puzzle pieces that fit together to cover the Earth`s surface.

Option 4: This statement is not correct. Along divergent plate boundaries, it is not subduction that carries plates into the mantle. Instead, it is the process of seafloor spreading that occurs at divergent boundaries. Here, two plates move apart, and new lithosphere is created as magma rises and solidifies to form new crust.

Alert - correct answer should be: "Along convergent plate boundaries, subduction carries plates into the mantle
