1. WEATHERING,EROSION,DEPOSITION Due Date: Dec. 10th
2. WEATHERING Definition: Wear away or change the appearance or
texture of something by long exposure to the air. Example: If you
took a piece of sand paper and you rubbed it against your skin, you
would have a scar. That is just like when sand or water rubs the
top off a treeless mountain, it rubs the top of the mountain off
gradually leaving it in a different condition. Illustration:
3. CHEMICAL WEATHERING Definition: The erosion or
disintegration of rocks, building materials, etc., caused by
chemical reactions. Types: water, oxygen, carbon dioxide, living
organisms and acid rain. Illustrate: Example: Lichen on a rock is a
form of chemical weathering. (caused by water)
4. MECHANICAL WEATHERING Mechanical weathering is the process
of breaking big rocks into little ones. The cool nights and hot
days always cause things to expand and contract. That movement can
cause rocks to crack and break apart. Mechanical weathering may
occur due to thermal fractioning, frost wedging, hydration
shattering, exfoliation and abrasion. During mechanical weathering,
external forces cause solid rock material to break into smaller
sediments. Illustration: Examples: when water freezes, it expands
and it pops things, like if you ever put a bottle in the freez- -er
it might pop..
5. EROSION erosion is the processes which remove soil and rock
from one location on the Earth's crust, then transport it to
another location where it is deposited. Types: Gravity, wind,
glaciers, water, and surface water. Illustrate: Examples: If the
wind blew sand of off a beach and it left a hole that would be
erosion.
6. DEPOSITION Deposition is the geological process in which
sediments, soil, and rocks are added to a landform or land mass.
Types: Temperature and wind Illustrate: Examples: If a garbage
truck drops trash off and that trash decomposes then its now been
deposited.
