Biosphere

What Is The Biosphere?
The biosphere is the layer of the planet Earth where life exists. This layer ranges from heights of up to ten kilometres above sea level, used by some birds in flight, to depths of the ocean such as the Puerto Rico trench, at more than 8 kilometres deep. These are the extremes; however, in general the layer of the Earth containing life is thin: the upper atmosphere has little oxygen and very low temperatures, while ocean depths greater than 1000 m are dark and cold. In fact, it has been said that the biosphere is like the peel in relation to the size of an apple.

Why is the Biosphere important?
How does the Biosphere Interacts with the other layers?
Another example is when volcanoes (lithosphere) erupt. Dust and ash particles (lithosphere) spread through much of the atmosphere and block sunlight. Less sunshine can cause a cooler, drier climate in parts of the world. Cooler climate affects the biosphere by shortening the growing season.
Yet another example is soil erosion, which occurs when rain (hydrosphere) falls on land (geosphere) denuded of vegetation (biosphere) by fire or clear-cutting. Streams and rivers (hydrosphere) become muddy or murky from erosion.
Another example would be...
Plants (biosphere) draw water (hydrosphere) and nutrients
from the soil (geosphere) and release water vapor into the
atmosphere. Humans (biosphere) use farm machinery
(manufactured from geosphere materials) to plow the
fields, and the atmosphere brings precipitation
(hydrosphere) to water the plants. Energy from the sun is
stored by plants (biosphere). When humans or animals
(biosphere) eat the plants, they acquire the energy
originally captured by the plants. Humans expend some of
this energy arranging bricks and wood (geosphere and
biosphere) into buildings. Plants (biosphere) draw water (hydrosphere) and nutrients
