THE 4 SPHERES
GEOSPHERE, ATMOSPHERE, HYDROSPHERE, AND BIOSPHERE
BY DANIELA SUAZO.
THE GEOSPHERE
• The term geosphere, is often used to refer to
the densest parts of Earth, which consist
mostly of Rock. Geo, means earth.
SPHERE
earth itself, rocks. Matle, core, crust.
constantly changing.
mountains built up and down due to crusion.
Types of pollutions on the geosphere
Domestic waste
Increase in urbanization
Industrial activities
Increase in agricultural land
Agricultural activities
ATMOSPHERE
THE GASEOUS ENVOLOPETHAT
SURROUNDS THE EARTH. ATMO
MEAN VAPOR
ATMOSPHERE
COMPOSED OF A MIXTURE OF GASES,THE
ATMOSPHERE PROVIDES LIVING THINGS WITH OXYGEN
AND CARBON DIOXIDE.
What threatens the sphere?
• Pollution in the air can be caused by
substances that are both man-made and
natural compounds. Find out how air pollution
can be caused by volcanic eruptions with help
from the chair of a department of
environmental studies in this free video on air
pollution.
HYDROSPHERE
• CONTAINS ALL THE
WATER IN THE EARTH
SYSTEM, INCLUDING
THE WATER IN THE
OCEANS, LAKES, AND
RIVERS, AND
GROUNDWATER.
Hydrosphere
• It contains 3% fresh water, most of the water
70% is frozen. In the form of glaciers. Only
about ½% is usable fresh water.
Types of pollutions in the hydrosphere
• Many causes of pollution
including sewage and fertilizers
contain nutrients such as nitrates
and phosphates.
• The pollution of rivers and
streams with chemical
contaminants has become one of
the most crutial environmental
problems within the 20th
century. Waterborne chemical
pollution entering rivers and
streams cause tramendous
amounts of destruction.
Biosphere
• The living things on the planet.
What’s the biosphere made of?
• Includes all forms of life
from single- celled
protozoans to jelly fish
to red wood trees to
people
• Basically plant, animals,
and humans
What threatens the biosphere.
• Human technology and population
growth can directly and indirectly disturb
the biosphere.
