Unraveling Earth's Four Spheres: Geosphere and Biosphere Insights

The video explains Earth's four spheres: geosphere, biosphere, hydrosphere, and atmosphere. It focuses on the geosphere, which includes all non-living elements like rocks and minerals, and the biosphere, which encompasses all living organisms. The video uses a forest meadow scene to illustrate how to identify elements belonging to each sphere, emphasizing the interconnectedness of these spheres in making Earth a habitable planet.

What are the four spheres that make up Earth?

• Geosphere, Lithosphere, Hydrosphere, Stratosphere

• Biosphere, Lithosphere, Atmosphere, Troposphere

• Lithosphere, Hydrosphere, Atmosphere, Stratosphere

• Geosphere, Biosphere, Hydrosphere, Atmosphere

In the forest meadow example, which element belongs to the geosphere?

• Deer

• Rock

• Grass

• Bird

Which sphere includes all living things?

• Geosphere

• Atmosphere

• Biosphere

• Hydrosphere

What is the main difference between the geosphere and the biosphere?

• The geosphere includes water, while the biosphere includes air.

• The geosphere is made of living things, while the biosphere is not.

• The geosphere is non-living, while the biosphere includes all living things.

• The geosphere includes air, while the biosphere includes water.

How do the geosphere and biosphere interact?

• The geosphere provides air for the biosphere.

• They work together to support life on Earth.

• They are completely independent of each other.

• The biosphere provides water for the geosphere.
