4 structures of earth systems - ANSWER-Hydrosphere
Biosphere
Lithosphere/Geosphere
Atmosphere
Lithosphere - ANSWER--Geosphere (ground)
-Refers to all of the rocks, minerals, and ground of the Earth
-Includes mountains, mantle and crust
-Thickness b/w 40-280km, ends at the point when the minerals
in earth's crust demonstrate viscous and fluid behaviors
-Divided into 12 tectonic plates, slowly moving plates
-If it looks like ground, it is part of the geosphere
, Hydrospere - ANSWER--Composed of all of the water on/near
earth's surface (oceans, rivers, lakes, underground aquifers and
moisture in the atmosphere)
-1.3 billion cubic km
-97% of earth's water found in the oceans, remainder is
freshwater or frozen
-accounts for very little of earth's total mass
-changes form as it moves through the hydrological cycle (water
cycle)
Biosphere - ANSWER--Composed of all living (life) organisms:
plants, animals, one-celled organisms
-3m below ground to 30 m above, up to 200m below in water,
thousands of meters above for birds and below for sea life
-made of biomes - areas where plants and animals of similar
nature can be found together
Atmosphere - ANSWER--Body of gases that surround our
planet, held in place by earth's gravity (air)
-Mostly located close to earth's surface where it is most dense
-Air is 79% nitrogen and just under 21% oxygen, argon, CO2,
and other gases fill rest of %
