Weathering: breakup of rock due to exposure to processes that occur on Earth’s surface
![Page 4: RAP 1/22 pg. 4](https://reader035.vdocument.in/reader035/viewer/2022062811/56816243550346895dd27d93/html5/thumbnails/4.jpg)
Two types:1. Chemical
-minerals are changed into different substances
2. Mechanical-split or broken into
smaller pieces*no change in composition

Lichen - a symbiosis between algae and fungus. Secretes acid. It is the most important producer
of soil from rock.

RAP 1/24 pg 41. Which rock was most likely found in
the bottom of a riverbed?
2. What type of weathering is responsible for the river rock?

Alka Seltzer Lab1. In your assigned group, perform TWO
trials of each variable.2. Record your data.3. When finished with ALL four trials, enter
your data into the spreadsheet on teacher computer.
4. Begin answering questions IN YOUR SEAT when done.

RAP 1/25 pg. 8
1.In the alka seltzer lab, what two things changed the weathering rates?
2. Which substance plays the most important role in chemical weathering?

Rates of Weathering1. Surface Area
2. Climate
3. Composition
a. More surface exposure = faster
a. Wet = faster; Dryer = slower
a. Faster = shale; Slower = quartz

Erosion has stripped away the overlying rock and Seneca Rocks have been uplifted
