What are the four main spheres of Earth?

Back

The four main spheres of Earth are the geosphere (land), hydrosphere (water), atmosphere (air), and biosphere (living things).

Front

What is the geosphere?

Back

The geosphere is the solid part of Earth, including rocks, soil, and landforms.

Front

What is the hydrosphere?

Back

The hydrosphere includes all of Earth's water, such as oceans, rivers, lakes, and glaciers.

Back

The atmosphere is the layer of gases surrounding Earth, essential for weather and life.

Front

What is the biosphere?

Back

The biosphere is the global sum of all ecosystems, where living organisms interact with each other and their environment.

Front

How do the geosphere and atmosphere interact during a volcanic eruption?

Back

During a volcanic eruption, ash and gases from the geosphere are released into the atmosphere, affecting air quality and climate.

Front

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

Back

An example is fish living in rivers and lakes, which are part of the hydrosphere, providing food and habitat for organisms in the biosphere.

Front

How does the cryosphere affect the hydrosphere?

Back

The cryosphere, which includes glaciers and ice, contributes to the hydrosphere by melting and providing fresh water to rivers and lakes.

Front

What is the significance of scientific theories changing over time?

Back

It indicates that scientific theories are revised as new evidence is discovered, reflecting the evolving nature of scientific understanding.

Front

What does the atomic number represent in the periodic table?

Back

The atomic number represents the number of protons in an atom's nucleus and determines the element's identity.
