Four Spheres of the Earth

Front

What is the atmosphere?

Back

The atmosphere is the layer of gases that surrounds the Earth, essential for life as it provides oxygen and protects from harmful solar radiation.

Front

What is the lithosphere?

Back

The lithosphere is the solid outer layer of the Earth, including the crust and upper mantle, composed of rocks and minerals.

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 is the hydrosphere?

Back

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

Front

What are the four spheres of the Earth?

Back

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

Front

How does the atmosphere support life?

Back

The atmosphere provides essential gases like oxygen for breathing, carbon dioxide for photosynthesis, and protects living organisms from harmful radiation.

Front

What role does the lithosphere play in ecosystems?

Back

The lithosphere provides the soil and minerals necessary for plant growth, which supports various ecosystems.

Front

What is an example of the biosphere?

Back

An example of the biosphere is a rainforest, which contains diverse plant and animal life.

Front

How does the hydrosphere affect weather patterns?

Back

The hydrosphere influences weather patterns through the evaporation of water, which forms clouds and precipitation.

Front

What is the relationship between the biosphere and the atmosphere?

Back

The biosphere relies on the atmosphere for gases necessary for life, while the biosphere contributes to the composition of the atmosphere through processes like respiration and photosynthesis.
