AIM: How do we solve weathering, erosion, deposition and
soil problems?
OBJ: Given notes and activity sheet SWBAT solve a variety
of different weathering, erosion, deposition and soil
problems with 70% accuracy
DN: Hand-in Sedimentary Rocks Lab write-up and SRL
Quiz scantron (Q:1-30).
ACT: Introduction to Soils, Superposition, Overturned Beds,
Lessons from the Earth’s History, Different Rock Types ~ Environments,
Spheres, Stream Velocity~Erosion, sediment size/shape ~ distance

Soil Profile
Soil = organic matter + rock fragments
= organic matter
LAW OF SUPERPOSITION
= top
= bottom
Overturned beds due to
folding & faulting
Environmental change occurs over time
Most life forms (organisms) have gone extinct
Evolution (most life forms change) over time
Life moves from simple to more complex organisms over time
Biodiversity increases over time; Extinction events occur over time
Different rock types with different
fossils = different environments
