lithosphere and asthenosphere
transition zone
skip 11/12 complete

Explanation:

The upper mantle contains the lithosphere (the rigid outer - most shell of the Earth) and the asthenosphere (a semi - fluid layer upon which the tectonic plates move). These components are crucial for plate tectonics and the dynamic behavior of the Earth's outer layers. Basaltic and granitic rocks are more associated with the crust. The area where plants and animals live is the biosphere. The transition zone is a part of the mantle but not the most defining feature of the upper mantle compared to the lithosphere and asthenosphere.

Answer:

lithosphere and asthenosphere
