Interactions of Earth’s Spheres

Fun Facts

  • Humans are part of the biosphere because we are living things.
  • The biosphere includes fish, birds, plants, and even people.
  • Living things interact with the other spheres because they need water, chemicals from the atmosphere, and nutrients.

Why Do We Need To Know About Biosphere

Learning about the biosphere helps us see how everything on Earth is connected and why it’s important to take care of our planet. The biosphere is all the living things on Earth. It’s affected by what humans do, like how recycling helps use less resources and causes less pollution. This is useful to know for jobs that work on protecting the environment and keeping our planet healthy.

When we recycle and reuse stuff, we help protect all the living things on Earth. This can also lead to jobs in making laws to protect the environment, and creating new technology that’s good for the planet. Doing projects like building something out of recycled materials shows us how important it is to think about the environment in our daily lives and can lead to jobs in designing things that are good for the planet.

What happened to the temperature of the atmosphere when hot water was added?
When hot water was added to the aquarium tank the temperature of the atmosphere above the land went up.
Does water temperature have an effect on air temperature?
