4 SPHERES OF THE EARTH

Front

What is the biosphere?

Back

The biosphere is the global sum of all ecosystems, where life exists, including land, water, and the atmosphere.

Front

What does the atmosphere consist of?

Back

The atmosphere is a layer of gases surrounding the planet, primarily composed of nitrogen (78%) and oxygen (21%).

Front

Define the hydrosphere.

Back

The hydrosphere encompasses all water on Earth, including oceans, rivers, lakes, and water vapor in the atmosphere.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and upper mantle.

Front

How do the biosphere and hydrosphere interact?

Back

The biosphere relies on the hydrosphere for water, which is essential for plant growth and animal survival.

Front

What is an example of an interaction between the atmosphere and hydrosphere?

Back

Water evaporation from lakes is an interaction where water moves from the hydrosphere to the atmosphere.

Front

What role does the lithosphere play in the biosphere?

Back

The lithosphere provides nutrients and minerals to plants, which are foundational to the biosphere.

Front

How does the atmosphere affect the hydrosphere?

Back

The atmosphere influences the hydrosphere through weather patterns, which affect precipitation and evaporation.

Front

What is the significance of the biosphere in Earth's systems?

Back

The biosphere is crucial for maintaining life, supporting biodiversity, and regulating ecosystems.

Front

Describe the relationship between the hydrosphere and lithosphere.

Back

The hydrosphere interacts with the lithosphere through processes like erosion, sediment transport, and groundwater recharge.
