Earth's Systems

Front

What are the four spheres of Earth?

Back

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

Front

What is the atmosphere?

Back

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

Front

What is the biosphere?

Back

The biosphere includes all living organisms on Earth, interacting with the other spheres.

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 encompasses all water on Earth, including oceans, rivers, and lakes.

Front

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

Back

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

Front

What role does the hydrosphere play in weathering?

Back

The hydrosphere contributes to weathering by providing water that breaks down rocks and minerals.

Front

How does the biosphere depend on the atmosphere?

Back

The biosphere depends on the atmosphere for oxygen, carbon dioxide, and climate conditions necessary for life.

Front

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

Back

An example is plants absorbing water from the soil (hydrosphere) to grow (biosphere).

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals through natural forces like wind, water, and chemical reactions.
