Biology Questions

Match each item to the sphere of Earth in which it is located: ozone layer, fossils, rust (iron oxide), cyanobacteria. Indicate whether each item belongs to the hydrosphere, atmosphere, or lithosphere.

Answer

The ozone layer is part of the atmosphere, fossils are located in the lithosphere, rust (iron oxide) is found in the lithosphere, and cyanobacteria belong to the biosphere. Each item corresponds to its respective Earth sphere. The Earth comprises four primary spheres that affect one another: the atmosphere, lithosphere, hydrosphere, and biosphere. To assign each item to its correct sphere, here’s the breakdown: Ozone layer: situated in the atmosphere, which envelopes the Earth with gases. Fossils: discovered within the lithosphere, encompassing solid rocks and minerals. Rust (iron oxide): usually forms on the lithosphere via chemical reactions. Cyanobacteria: included in the biosphere, representing all living entities on the planet.
