PSSA ANCHORS - S.8.D.1 Geologic Processes

ASSESSMENT ANCHOR
S8.D.1 Earth Features and Processes that Change Earth and Its ResourcesELIGIBLE CONTENT
S8.D.1.1 Describe constructive and destructive natural processes that form different geologic structures and resources.Reference: 3.5.7.A, 4.4.7.B
S8.D.1.1.2 Describe natural processes that change Earth’s surface (e.g., landslides, volcanic eruptions, earthquakes, mountain building, new land being formed, weathering, erosion, sedimentation, soil formation).
S8.D.1.1.3 Identify soil types (i.e., humus, topsoil, subsoil, loam, loess, and parent material) and their characteristics (i.e., particle size, porosity, and permeability) found in different biomes and in Pennsylvania, and explain how they formed.

CHECK YOURSELF ON SOIL TYPES, PARTICLE SIZES, AND POROSITY vs. PERMEABILITY
1) What is the relationship between porosity and permeability of soil?
2) What is the relationship between particle size of soil and permeability?
3) Tell what soil type each of these mixtures is according to the soil type triangular chart above:
a. 30% clay, 50% sand
b. 80% sand, 10% silt
c. 40% sand, 20% clay, 40% silt
d. 30% clay, 40% sand
4) What % silt is a soil that has 30% clay and 10% sand? What type of soil is this?
5) Put these soil types in order from highest permeability to lowest:

clay, sand, clay loam, sandy loam
