Detailed Solution

The four realms of the Earth are the lithosphere, hydrosphere, atmosphere, and biosphere.

These four parts cover land, water, air, and life. They work together and keep Earth stable. Understanding their links helps explain weather, climate, soil, water cycle, and living systems.

How they interact

Water cycle: Ocean (hydrosphere) evaporates to air (atmosphere), forms clouds, rains on land (lithosphere), supports life (biosphere).
Soil formation: Rocks (lithosphere) weather with water and air to make soil that feeds plants (biosphere).
Climate: Atmosphere controls temperature and rainfall, shaping life zones in the biosphere and erosion on land.

Healthy balance between these realms is vital. Human actions like deforestation, pollution, and overuse of water disturb this balance. Good management of soils, water, air quality, and ecosystems protects all four.
