The environment may contain ___________________ levels of substances that are harmful to
human beings. Therefore, the good health of individuals requires monitoring the __________,
__________ and water and taking steps to make these factors safe for all organisms. Evaluate ways
in which _________________ activities have affected Earth’s pedosphere and the measures taken to
control the impact: vegetative cover, ____________________such as (contour plowing, conservation
plowing), land use, nutrient balance (crop rotation), soil as a vector. Technology, such as
_______________ sensing, has allowed humans to better study the human impact on soil quality and
erosional processes so that the soil can be protected and ___________________. Over time, remote
sensing information can tell us how humans are constantly __________________ the surface of the
Earth and what impact these changes are likely to produce. Technologies can also assist in finding
ways to help prevent __________________. It is important that humans take care of the earth.

weathering
Although _________________ rock is the basic component of soil, the composition and texture of soil
and its fertility and resistance to erosion are greatly influenced by _____________ roots and debris,
bacteria, fungi, worms, _____________, rodents, and other organisms. The upper-most layer of the
___________________ crust is covered by soil. The ingredients in soils can vary from
_____________ to place and around the Earth. Different soils have many properties such as texture,
_______________size, pH, fertility and ability to hold moisture. Depending upon the combination of
____________________, soils have great variability in their ability to support structures and plant
growth. Forces deep inside Earth and at the surface produce a slow cycle that builds, destroys, and
_________________ the rocks in the crust. Plate movements start the rock cycle by helping to form
magma, the source of ___________________ rocks. _____________ movements also cause
faulting, folding and other motions of the crust that help to form sedimentary and
_____________________ rock. Minerals form as hot magma cools inside the crust, or as lava
hardens on the surface. When these liquids cool to a ______________ state, they form crystals.
When elements and compounds that are dissolved in water leave a solution, crystallization of
________________ occurs. Soil is a mixture of: rock particles, minerals, decayed _______________
matter, water and air. Soil forms as rock is broken down by _________________ and mixes with
other materials on the surface.
EROSION NOTES
1. ________________ and _______________ Forces wear down and build up Earth’s Surfaces
2. Natural Forces move and deposit sediments which created the __________________________.
3. Erosion- _________________________________ are picked up and moved to a new place
____________________- the part of the erosion process in which sediment in placed (deposited) in a
new location
4. Gravity is the force holding everything _____________ on Earth. This force causes ___________
to move __________________ (think from the top of a mountain to the bottom)
5. Three Types of Erosion
_______________erosion- rivers, streams carry sediment and deposit sediment at river bottom,
floodplain, and mouth of the river
____________ erosion- Strong winds life tiny particles of dust and carry them long distances
_________erosion- As ice moves slowly it carries with it rock and soil particles frozen inside of the ice
6. Floodplain- area of land on either side of the _______________ that is underwater when the
stream _______________
9. _________________ Weathering: rock is ______________ broken into smaller _____________
that have the same chemical composition as the rock they came from.
–Examples: _________________________, __________________________
10. _________________Weathering: the _______________ that breaks down rock through
___________________changes and produces rock particles that have a ________________mineral
makeup from the rock they came from.
–Examples: ____________________________, __________________________________
11. Soil ____________________:
15. TWO TYPES: _______________________________, _________________________________
