Earth's Spheres

What are Earth's spheres?

Back

Earth's spheres refer to the four main components of the Earth system: the atmosphere (air), hydrosphere (water), geosphere (land), and biosphere (living things).

Front

What is the atmosphere?

Back

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

Front

What is the hydrosphere?

Back

The hydrosphere includes all the water on Earth, such as oceans, rivers, lakes, and groundwater.

Front

What is the geosphere?

Back

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

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 spheres interact?

Back

The spheres interact through processes like the water cycle, where water evaporates from the hydrosphere, forms clouds in the atmosphere, and falls as precipitation.

Front

What is an example of the hydrosphere interacting with the atmosphere?

Back

The ocean affecting air temperature is an example of how the hydrosphere interacts with the atmosphere.

Front

What role does the sun play in Earth's spheres?

Back

The sun provides energy that drives processes and interactions among Earth's spheres, such as weather patterns and the water cycle.

Front

What is an example of a positive human action for Earth's spheres?

Back

Recycling plastic is a positive human action that can benefit all of Earth's spheres by reducing waste and pollution.

Front

What happens when rain falls on plants?

Back

When rain falls on plants, it waters them, helping them to grow, which is an interaction between the hydrosphere and biosphere.
