WHAT IS BIOSPHERE?

The biosphere is a group of spheres or layers where life on Earth is possible. It includes all the places where life can be found — on land, in the water, and in the air.

THE BIOSPHERE

The biosphere is composed of all the ecosystems on earth where there is life.

It contains three systems:

The atmosphere

The hydrosphere

The lithosphere

THE ATMOSPHERE

The atmosphere is made up of layers of gases that surround the earth.

These layers provide living things with air to breathe, trap heat to warm earth and create a protective layer from the Sun.

LAYERS OF THE ATMOSPHERE

Exosphere

Thermosphere

Mesosphere

Stratosphere

Troposphere

THE HYDROSPHERE

The hydrosphere is made up of all the water found on, under and above the earth's surface.

This water can be found as liquid, vapor or ice and makes up the water cycle on Earth.

WHERE IS THE HYRDOSPHERE?

Anywhere you can find water!

Clouds

Glaciers

Lakes

Ground Water

Oceans

Rivers

THE LITHOSPHERE

The lithosphere is the outer layer of the Earth, made up of the crust and upper mantle.

These layers provide plants with the nutrients needed to grow and contain the different rocks from the rock cycle.

ALL ABOUT THE LITHOSPHERE

There are two types of lithosphere:

Oceanic Lithosphere

Continental Lithosphere

The lithosphere is broken into plates and is often known for it's plate tectonics, the movement that causes earthquakes, volcanos and create various landmarks.

CONCLUSION

The three systems of the biosphere allow life to sustain itself on earth and provide us with Important details regarding earth's systems. Think of adaptations of the structure and the function of living things in these spheres.

Explain how the lithosphere supports life on Earth.

• The lithosphere provides a surface for plants to grow and for animals and humans to live on.
• It contains minerals and nutrients in the soil that plants need to grow, and these plants form the base of the food chain.

• Example: Farmers use soil from the lithosphere to grow crops like maize, which feed both humans and animals.

Illustrate with examples how living organisms depend on the different parts of the biosphere.

• From the lithosphere, plants get nutrients from the soil.

• From the hydrosphere, all living things get water to drink or live in.

• From the atmosphere, animals and humans breathe in oxygen, while plants use carbon dioxide to make food.

Example:A frog depends on all three parts — it lives on land (lithosphere), lays eggs in water (hydrosphere), and breathes air (atmosphere).

Discuss the interactions between the lithosphere, hydrosphere, atmosphere, and living organisms. All parts of the biosphere are connected and interact to support life:

• Rain (from the atmosphere) falls onto the land (lithosphere) and into rivers (hydrosphere).

• Plants (living organisms) absorb water from the soil and carbon dioxide from the air to make food.

• Animals eat plants and breathe in oxygen from the air.

• These interactions create a balance in nature that keeps life on Earth possible.
