Final answer:
Minerals belong to the geosphere, which is part of Earth’s solid crust and includes various types of rocks that contribute to geological processes.
Step-by-step explanation:
The part of the Earth that belongs to the geosphere is minerals (option 3). The geosphere encompasses the interior structure of the Earth, which includes its rocks and minerals. It is distinct from the hydrosphere (water), atmosphere (air), and biosphere (all living things, including plants).
The geosphere consists of the Earth's solid crust and comprises terrestrial rocks which can be classified as igneous, sedimentary, or metamorphic.
The soil, which is part of the lithosphere, obtains its mineral nutrients from these rocks. Earth's interior composition is critical for understanding various geological processes such as continental drift, mountain building, and plate tectonics that shape the planet's surface.
