Asthenosphere- the layer of earth
located in the outer part of the mantle.
Lithosphere- the earth’s layers that
are located at the outer most layer of the earth.
Plate Tectonics- a theory stating
that the earth is divided into plates.
Tectonic Cycle- The process of
building up and breaking down the lithosphere.
Divergent Plate Boundaries- the area
beneath the ocean that contains the code for reproducing the next generation.
Convergent Plate Boundaries- An area
where plates move towards each other.
Transform Fault Boundary- the area
where tectonic plates move sideways towards each other.
Physical Weathering- the breakdown of
rocks caused by natural disasters.
Chemical Weathering- the break down
of rocks caused by chemical reactions.
Erosion- The physical removal of rock
fragments from a landscape or ecosystem.
Deposition- The accumulation or
depositing of eroded rock material.
Cation Exchange Capacity-ability of
soil to absorb.
Base Saturation- the ratio of soil
bases to soil acids.
Soil Degradation- the loss of
some or all of a soil’s ability to support growth.
Ores- concentrated accumulation of
minerals from which economically valuable materials can be extracted.
BIG Picture Reflection!
Human Impact- Human activity can
very much impact soil. A major thing that can impact soil is pollution. When a
soil has been polluted it will loose certain nutrients that livings things need
to live. In class we learned about soil and took measures of our soil samples
to see what our soils were lacking and pollution can be a large impact on why
some soils are lacking.
Environmental Impact- Also explained in
human impact, the pollution of soil can have a large impact on the environment.
Most importantly, the animals that live in the soil will not be able to live
there and the animals and humans that rely on the food that grows in the ground
will starve. However not all of the soil on earth is polluted so when a soil is
healthy and rich in nutrients it causes the animals around it to also be
healthy.
Economic Impact- During the notes in
class we learned about Ores, which are worth a lot of money today. For an
example, Mrs.Kays talked about the drillings near East Texas. These ore
drillings are a big economic impact on the people who own the land making them
more rich and also the people selling the products found.
Government Legislation- The United States
government has recently discovered how disgusting pollution is and is finally
doing something about it but as more years go by the laws are getting to be
better. The government has laws against where people can drill to reach ores so
that the soil around them is not completely destroyed.
