what are the 4 spheres and what do they cover? give an example of each

Explanation:

The seasons on Earth are caused by the tilt of Earth's axis as it orbits the Sun. This tilt causes different parts of the Earth to receive varying amounts of sunlight at different times of the year. The four spheres are the lithosphere (solid outer - layer of Earth, e.g., mountains), hydrosphere (all water on Earth, e.g., oceans), atmosphere (layer of gases surrounding Earth, e.g., oxygen in air), and biosphere (regions of Earth where life exists, e.g., a forest ecosystem).

Answer:

What causes the seasons on the Earth? - The tilt of Earth's axis as it orbits the Sun.
