2. Hydrosphere  The hydrosphere is all the water or frozen water in the earth.  The Earth is 70% water!  It’s all made up of oceans, lakes, rivers, streams, glaciers and ground water.  The hydrologic cycle begins with evaporation.  Then the vapor goes to the clouds.  Once the water gets back to the ground, the water could evaporate again or the water becomes ground water.

3. Biosphere  The Biosphere includes all the living things in the earth.  There is all kinds of organisms that make up the biosphere.  Some organisms are the animals, humans, plants, and bugs.  The biosphere is where all the spheres work together.  The biosphere is very important because it helps with the other spheres  If there wasn’t such thing as the biosphere there maybe wouldn’t be an earth.

4. Atmosphere  The depth is 62 miles.  The pressure increases with height.  First it’s the troposphere, then the stratosphere, then the Mesosphere, and last is the Thermosphere.  It saves earth from harmful rays of sun  It controls the temperature and doesn’t let the earth cool fast or heat up.  It holds like gasses oxygen and carbon dioxide.

5. How do all the spheres interact?  The atmosphere interacts with the biosphere because it has oxygen.  The hydrosphere interacts with all the sphere providing water for them.  The biosphere interacts with the hydrosphere because it has water for us to live.  The lithosphere is in interaction with all the other spheres.  The biosphere (us) built a dam made out of rocky crust (like the lithosphere.)  There is water in the dam (hydrosphere) made of rocky crust (lithosphere.)

6. Lithosphere  Lithosphere is the rocky crust covering the entire earth.  It has a depth of 60 miles.  Its broken to a whole bunch of plates called plate tectonics.  Plate tectonics- it is plastic like rocks that move caused by the convection currents of heat.  Volcanism- can occur along the edges of an ocean ridge.  200 million years ago the continents spread apart and moved away from each other.
