Matter Cycles Notes Review

Front

What are the Earth's spheres?

Back

The Earth's spheres include the biosphere (living organisms), geosphere or lithosphere (rocks and soil), hydrosphere (water), and atmosphere (air).

Front

What is the geosphere or lithosphere?

Back

The geosphere or lithosphere refers to all of Earth's rocks and soil.

Front

What happens to carbon when fossil fuels are burned?

Back

When fossil fuels are burned, carbon is released into the atmosphere.

Front

What is meant by 'cycled' in the context of matter and energy?

Back

Cycled means that matter and energy are continuously moved and transformed through the geosphere, hydrosphere, atmosphere, and biosphere.

Front

Define an ecosystem.

Back

An ecosystem is a community of living organisms interacting with each other and their nonliving environment.

Front

What is recycled through photosynthesis and respiration?

Back

Carbon is recycled through photosynthesis and respiration in nature.

Front

What is the biosphere?

Back

The biosphere is the global sum of all ecosystems, where life exists on Earth.

Front

What role does the hydrosphere play in matter cycles?

Back

The hydrosphere includes all water on Earth, which is essential for transporting nutrients and supporting life.

Front

How does the atmosphere interact with the other spheres?

Back

The atmosphere interacts with the geosphere, hydrosphere, and biosphere by exchanging gases, weather patterns, and supporting life.

Front

What is the significance of the carbon cycle?

Back

The carbon cycle is significant because it regulates Earth's climate and supports life by recycling carbon through various processes.
