It includes all the air in
the earth.
 It has four mane layers ionosphere,
Mesosphere ,Troposphere ,and the
stratosphere.


The present composition of the atmosphere is
79% nitrogen, 20% oxygen, and 1% other
gases.

The atmosphere is 371 miles long.

The atmosphere protects us from high
energy radiation and the frigid vacuum
of space.

Earths atmosphere protects life on the
planet.
The hydrosphere includes all the water in
the earth.
 Water is the most common substances
on the earth.
 Scientist believe that the amount of
water on earth does not change.
 Water in the ocean moves in huge
currents of water.


Water is everywhere in your body in the
air and in rocks.

The ocean is 70% of the hydrosphere 20%
is in the air 10% in lakes and ponds.
The biosphere is the biological
component of earth systems, which also
include the lithosphere, hydrosphere,
atmosphere and other spheres.
 The biosphere includes all living
organisms on earth even the dead things
on earth.
 It also includes the rocks the dirt and that
matter.


The biosphere cannot exist without the
other spheres.

The biosphere is the defended as the
sphere or area around earth.

The biosphere is the largest sphere that
exist.
In Antarctica the thick ice cap has
pushed the lithosphere below sea level
today.
 Construction of volcanoes, Deposition of
sediment ,Rise in sea level, Formation of
large lakes and reservoirs are all kinds of
loading.
 the lithosphere is actually part of the
upper mantel and crust.

The lithosphere is basically the layer of
the earth that is strong enough to flex
rather than flow.
 Its top is easy to see its at the Earths
surface but the base of the lithosphere is
a transition rather than a sharp
boundary.
 It flexes when loads are placed on it or
took off.

The biosphere drinks the hydrosphere and
is part of the lithosphere, and gives off to
the atmosphere. the hydrosphere is in
the atmosphere and the water goes into
the clouds. There is moister in the dirt and
rock of the lithosphere. The lithosphere is
the dirt and minerals that plants need to
live. And they help each other.
