0. The 'Spheres' of Planet Earth!
The Earth's Atmosphere
What do we mean by the atmosphere?
The band of gases held by gravity
above the Earth's surface, mainly nitrogen N2 and oxygen
O2. Air
is a mixture of gaseous molecules, some are elements like oxygen and
nitrogen, and others are compounds like carbon dioxide and air
pollutants like the oxides of sulfur and nitrogen. |
The Earth's Hydrosphere
What do we mean by the hydrosphere?
All the water of lakes, rivers, seas
& oceans on the Earth's surface.
The waters contain many dissolved
substances, many of them ionic compounds like salts e.g. sodium
chloride NaCl, magnesium chloride MgCl2, magnesium
sulfate MgSO4, potassium bromide KBr |
The Earth's Lithosphere
What do we mean by the lithosphere?
The solid crust and almost solid upper mantle of the
Earth's upper rock layers. The lithosphere is a complex mixture
of minerals. |
The Earth's Biosphere
What do we mean by the biosphere?
All the living systems that reside on
or near the Earth's surface. Life of many forms has adapted to exist in water, in air and
on land. |
