2.  The lithosphere is the outermost shell of a rocky planet.  The lithosphere is the crust and upper mantel of the Earth.  The older the lithosphere the stronger it is.  The lithosphere is mostly magma.  The lithosphere is broken up into tectonic plates.  The lithosphere is 12000 degrees.

3.  The water on Earths surface.  Hydrosphere is Greek for “water”.  The water under and on the surface of a planet.  The total mass of the Earth’s hydrosphere is about 0.023% of Earth’s mass.  The hydrosphere cover 75% of the Earth’s surface.  The Earth’s oceans are 35 grams of salt.

4.  Atmosphere is Greek for “vapor”.  The atmosphere is a layer of gas that surrounds planets.  The atmosphere is held in place by the gravity.  The Earth’s atmosphere contains oxygen.  Some planets atmosphere is made of gas.  An atmosphere may be retained for longer duration, if the gravity is high and the atmosphere’s temperature is low.

5.  The biosphere is the global sum of all ecosystems.  It can also be called the zone of life on Earth.  Physical geographers use the term biosphere to describe our living world.  The biosphere is all life on Earth.  The biosphere is said to have evolved some 3.5 billion years ago.  Every part of the planet, from the polar ice caps to the equator, supports life of all kind of life.

6.  They all interact equally with each other and the planet  The animals that die are descomposed, and the nutrients now form part of the lithosphere.  The animal breathing changes the atmosphere.  The animals blood or waste can change the hydrosphere.  A change in the biosphere, lithosphere, atmosphere, or hydrosphere can change the biosphere.  A change in the atmosphere can evaporate the water, can kill the animals and plants and change in temperature can break the lithosphere.
