GEOGRAPHY  THE BIOSPHERE The biosphere is composed of all the ecosystems on earth where there is life. It contains three systems: The The The atmosphere hydrosphere lythosphere 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 The final layer stretches into space and houses satellites. Thermosphere This is the hottest layer because it absorbs the sun's radiation. Auroras occur in this layer. Mesosphere The coldest layer which protects us from meteors because they burn up in this layer. Stratosphere The ozone is found in this layer protecting us from UV rays Troposphere The layer in which we live and weather occurs.  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 Oceans Ground Water 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: Continental Oceanic Lithosphere 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.
