Transcript The Different Spheres of Earth

Lithosphere

The Lithosphere is the outer part of the Earth including the
crust and the upper mantle that is broken into plate tectonics
Plate tectonics describe the large scale motions of the
lithosphere. There are currently eight major and many minor
plates
The Lithosphere also has volcanism which is volcanoes. A
Volcano is a opening in the earths crust that allows magma,
ash, and gases to escape from below the earths surface.
Volcanoes are usually found where tectonic plates are pulled
apart.
The Lithosphere also has earthquakes. A earthquake is a
sudden release of energy in the earths crust that causes the
earth to shake. A earthquake is caused by tearing of
geological faults, volcanic activity, mine blasts, ect.
Continental drift is the movement of the continents on earth.
There was no explanation to why this happened until people
found out about tectonic plates in the 1960s.
Hydrosphere

The Hydrosphere is all the earths water.
The movement of water over, around and though the earth is
called the Water Cycle which is a very important part of the
Hydrosphere.
The hydrosphere consists of:
Rivers which is a natural watercourse, usually freshwater
flowing toward a ocean, lake, or sea.
Aquifers which is a underground layer of water-bearing rock,
gravel, sand, silt, or clay. From which groundwater can be
extracted using a water well
Precipitation which is rain, snow, sleet, and hail pulled down
from the sky by gravity.
Biosphere



The Biosphere is the global sum of all ecosystems.
Almost every part of the earth is covered by a living thing
and all living things are a part of the biosphere, it doesn’t if it
is on the ground or in the air if its living it’s in the biosphere.
All the spheres use each other but the Biosphere is special
because it needs itself and almost all the other spheres to
survive because it needs the hydrosphere for the water for
the animals and plants to live and it needs the lithosphere
for the land and itself for the animals for the predators to eat.
Atmosphere




The Atmosphere is a layer of gases that may surround a
body of mass.
Atmospheric pressure is the force per area that is applied to
a surface by the surrounding gas. The height at which the
pressure from an Atmosphere declines is called the scale
height, and that is how they are related.
The Atmosphere has five layers the first is the troposphere,
second is the strosphere, third is the mesosphere, fourth is
the thermosphere, and last is the exosphere.
The Atmosphere protects the earth from the suns rays,
controls the earths temperature, and holds important gases
like oxygen and carbon dioxide.
How The Spheres Interact



Pollution is the chemicals into an environment that causes
harm to the ecosystem. This involves all the spheres
because power plants are made from materials found in the
Lithosphere. The power plants release pollution into the
atmosphere, and that same pollution is harmful to the
humans and animals in the Biosphere, and the water in the
hydrosphere is also harmed by pollution.
Erosion is a gravity driven process that moves solids such as
rock witch is a part of the Lithosphere. Erosion can be sped
up by water in the Hydrosphere and by humans in the
biosphere. Then over a period of thousands of years is either
grown or ground up and released back into the layers of the
Atmosphere.
A flood is an overflow of water released by the Hydrosphere
onto the ground of the Lithosphere. This can be deadly to the
humans and animals of the Biosphere. Then when it is over
it is dried up, turned into water vapor, then released to the
Atmosphere, and finally is turned into another series of rain
clouds.
