Reading Checks:
Pg166: The chemical weathering undergoes the process of processing
the rocks formation and change into a new forming composition.
Pg168: Different climates have different rates of weathering because the
rate of weathering of Earth materials has a major effect on what type of
weathering would exactly occur. Such weathers are precipitation,
temperature, and evaporation lead to affects on climate. Among the two
ranges of weather temperature and precipitation often effect one
another and then determines the weathering rate in a given region.
Pg172: The time of year water has the most potential for erosion is
during the high season of summer/fall.
Pg177: Residual soils are different from transported soils because it is a
soil whose parent material is the local bedrock. In transported soil, it is
the soil that develops from parent material that has been moved far
from its original location.
Pg178: The difference between a mature and an undeveloped soil is that
is the a vertical sequence of soil layers. Mature soils have more distinct
layers than others, known as the undeveloped: soils that have not
developed distinct layers.
Pg180: Microorganisms affect soil formation because they decompose
dead plants and animals. Plant roots may open their roots and when
things decompose, they are adding organic material to the soil.

10. Weathering: is the process in which materials on or near Earth’s
surface break down and change. Erosion: The removal of
weathered rock and soil from its original location.
11. Chemical weathering: is the process by which rocks and minerals
undergo changes in their composition. Mechanical weathering: is
a type of weathering in which rocks and minerals break down into
small pieces.
12. Gully erosion: when a channel becomes deep and wide, rill
erosion evolves into a Gully erosion. Rill erosion: develops
when running water cuts small channels into the side of a slope.
13. Soil horizon: A distinct layer within a soil profile is called a soil
horizon. Soil profile: is a vertical sequence of soil layers.
14. Erosion: The removal of weathered rock and soil from its
original location.
Deposition: After the materials are
transported, they are dropped in another location.
15. Residual Soil: a soil whose parent material is the local bedrock.
Transported soil: is soil that develops from parent material that
has been moved far from its original location.
