FAQs on Mindmap: Major Domains of the Earth - Social Studies (SST) Class 6

1. What are the major domains of the Earth?
Ans. The major domains of the Earth are the lithosphere, hydrosphere, atmosphere, and biosphere. The lithosphere refers to the solid outermost layer of the Earth, including the crust and upper mantle. The hydrosphere encompasses all the water on Earth, including oceans, lakes, rivers, and groundwater. The atmosphere is the layer of gases surrounding the Earth, which is essential for supporting life and weather patterns. The biosphere includes all living organisms and their interactions with the other domains.
2. How does the lithosphere contribute to the Earth's domains?
Ans. The lithosphere plays a crucial role in the Earth's domains. It provides a solid surface for the other domains to interact with. For example, the hydrosphere includes bodies of water that exist on the lithosphere, such as oceans and lakes. The lithosphere also interacts with the atmosphere through processes like erosion and weathering. Additionally, the lithosphere supports the biosphere by providing habitats for various organisms.
3. What is the significance of the hydrosphere in the Earth's domains?
Ans. The hydrosphere is vital for the Earth's domains as water is essential for life and plays a significant role in shaping the planet. It provides habitats for numerous organisms and supports various ecosystems. The hydrosphere also influences climate patterns through processes like evaporation, condensation, and precipitation. Furthermore, it acts as a medium for transportation and plays a crucial role in nutrient cycling.
4. How does the atmosphere contribute to the Earth's domains?
Ans. The atmosphere is a crucial domain of the Earth as it provides the air we breathe and plays a vital role in supporting life. It regulates temperature, weather patterns, and climate. The atmosphere also protects the Earth from harmful radiation and meteors. It is involved in the water cycle, transporting moisture and facilitating precipitation. Additionally, the atmosphere interacts with the other domains through processes like wind erosion and atmospheric deposition.
5. What role does the biosphere play in the Earth's domains?
Ans. The biosphere is the domain of the Earth that includes all living organisms. It interacts with the other domains in several ways. For instance, the biosphere depends on the hydrosphere for water and nutrients. It also interacts with the atmosphere through processes like respiration and photosynthesis. The biosphere is influenced by the lithosphere as it provides habitats and resources for organisms. Additionally, human activities have a significant impact on the biosphere, affecting the overall balance and sustainability of the Earth's domains.
