What is the geosphere?

The geosphere is all of Earth’s rocks and minerals that make up its surface. The word “Geo” means Earth.

What is the hydrosphere?

The hydrosphere is all the water on planet Earth. The word “Hydro” means water.

What is the atmosphere?

The atmosphere is all of the gases surrounding Earth. That includes the air we breathe. The word “Atmos” means air.

What is the biosphere?

The biosphere is all the life forms on Earth. That includes all the animals, humans, plants and trees. The word “Bio” means life.

In the investigation with aquariums, which of Earth’s spheres are represented?

The team uses sand to represent land, which is part of the geosphere. They use water to represent the hydrosphere and the air in the tank represents Earth’s atmosphere.

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?

Yes, water temperature does affect atmospheric temperature. When hot water was added to the aquarium tank, the temperature above the land when up. When cold water was added, the air temperature went down.

Which two of Earth’s spheres are represented in the example of erosion?

Dr. Jeff uses a sand blaster (moving air containing sand particles) to erode rock. The air from the sand blaster represents wind in the atmosphere and it breaks down rock (that’s geosphere).

How did the example with dry ice show that land affects water and air?

The team uses dry ice (frozen carbon dioxide) to create fog. The sand mountain (geosphere) blocked the fog from moving to the other side of the aquarium. This shows that the shape of the land affects the weather.

Which of Earth’s spheres are humans part of? Why?

Humans are part of the biosphere because we are living things. The biosphere includes ALL living things.

Which of Earth’s spheres do humans impact? Give examples.

Humans can impact all four of Earth’s spheres. Humans can burn fossil fuels and release pollution into the atmosphere. Humans pile up garbage in landfills affecting the geosphere. Humans produce waste that flows into water bodies impacting the hydrosphere. Humans also impact the biosphere by cutting down trees. Humans also work to lessen their impact on the spheres through actions like recycling.

How does using recycled materials help Earth’s spheres?

Using recycled materials like those that Zoe uses to build her race car means additional resources from Earth’s spheres do not have to be used. By using recycled cardboard and skewer, Zoe helps keep fewer trees in the biosphere from being cut down. Using old washers means no new metal needs to be mined from the geosphere. Using old CDs that would have otherwise ended up in a landfill lessens impact on the geosphere. Using a reusable water bottle instead of a single use bottle means less plastic needs to be made.

DEFINITION OF EARTH’S SPHERES

The spheres are the four subsystems that make up the planet Earth. They are called spheres because they are round, just like the Earth. The four spheres are the geosphere (all the rock on Earth), hydrosphere (all the water on Earth), atmosphere (all the gases surrounding Earth), and biosphere (all the living things on Earth).

To better understand how the 4 spheres of the Earth work….

LET’S BREAK IT DOWN!

Earth’s land makes up the geosphere.

Geo means “earth.” The Earth’s geosphere (sometimes called the lithosphere) is the portion of the earth that includes rocks and minerals. It starts at the ground and extends all the way down to Earth’s core.

We rely on the geosphere to provide natural resources and a place to grow food. Volcanos, mountain ranges, and deserts are all part of the geosphere. Put simply, without the geosphere, there would be no Earth!

Earth’s water makes up the hydrosphere.

Hydro means “water.“ The hydrosphere includes the oceans, rivers, lakes, groundwater, and water frozen in glaciers. 97% of water on Earth is found in the oceans. Water is one of the most important substances needed for life and makes up about 90% of living things. Without water, life would not be possible.

Earth’s air makes up the atmosphere.

clouds in the sky represent the atmosphere

Atmos means “air.” The atmosphere includes all the gases surrounding the Earth. We often call the atmosphere "air." All planets have an atmosphere, but Earth is the only planet with the correct combination of gases to support life.

The atmosphere consists of five layers and is responsible for Earth’s weather. Even though it seems like air is made of nothing, it consists of particles too small to be seen. All these particles have weight that push down on Earth. The weight of air above us is called air pressure.

Earth’s living things make up the biosphere.

Bio means “life.” The biosphere is made up of all the living things on Earth and it includes fish, birds, plants, and even people.

The living portion of the Earth interacts with all the other spheres. Living things need water (hydrosphere), chemicals from the atmosphere, and nutrients gained by eating things in the biosphere.
