DSST Introduction to Geology · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Core knowledge

  • Define the three rock classes and list two diagnostic properties that separate each class from the other two

  • Sketch and label the rock cycle, naming at least two processes that convert each class into each other class

  • Identify the 12 most common rock-forming minerals from their physical properties (hardness, cleavage, luster, streak) without a reference sheet

  • Explain how Bowen's reaction series predicts which minerals crystallize first in a cooling magma and what that implies for melt composition

  • Build a one-page mineral-identification decision key that you can reconstruct from memory

Your checkpoint

A hand-drawn rock cycle diagram plus a self-made mineral ID key, both scored against a textbook figure with every error corrected in a different color

Week 2

Core knowledge

  • Distinguish intrusive from extrusive igneous textures and match each to its cooling history

  • Classify sedimentary rocks as clastic, chemical, or biochemical and give the grain-size terms for clastic varieties

  • Compare foliated and nonfoliated metamorphic rocks and rank four examples by increasing metamorphic grade

  • Interpret a simple stratigraphic column using superposition, cross-cutting relationships, and original horizontality

  • Explain the difference between relative and absolute dating and describe how radiometric decay provides ages

Your checkpoint

A 25-question self-written quiz covering rock classification and relative dating, with an answer key and a written explanation for each answer

Week 3

Core knowledge & Surface processes

  • Describe mechanical and chemical weathering processes and predict which dominates in hot-wet versus cold-dry climates

  • Sequence the steps of soil formation and name the horizons in a mature soil profile

  • Trace the erosion, transport, and deposition path of sediment from hillslope to ocean basin

  • Explain how sorting, rounding, and grain size record transport distance and agent

  • Compare the erosional and depositional landforms produced by rivers, glaciers, wind, and waves

Your checkpoint

A comparative table of four erosional agents listing transport mode, typical deposit, and two landforms each, checked against course notes

Week 4

Surface processes

  • Diagram the hydrologic cycle and quantify where the largest reservoirs of Earth's water sit

  • Explain drainage basin morphology, stream ordering, and how a hydrograph responds to a storm

  • Distinguish meandering from braided channels and predict where erosion and deposition occur in each

  • Describe groundwater flow through an aquifer and define porosity, permeability, water table, and cone of depression

  • Interpret a topographic map to compute gradient and locate a floodplain and a water divide

Your checkpoint

A worked topographic-map exercise: gradient calculation, drainage-basin outline, and a labeled stream cross-section, all with units shown

Week 5

Tectonic earth processes

  • Label Earth's internal layers by composition and by physical behavior, and state the evidence for each boundary

  • Explain plate tectonics as the unifying theory and list the lines of evidence that supported continental drift before seafloor spreading

  • Compare divergent, convergent, and transform boundaries in terms of stress, fault type, and typical landforms

  • Relate the three plate boundary types to the location and depth of earthquakes and to volcanic style

  • Interpret a simple map of global earthquake and volcano belts to infer plate margins

Your checkpoint

An annotated plate-boundary map identifying each boundary type, its stress regime, its seismic signature, and one real example per type

Week 6

Tectonic earth processes

  • Describe the elastic-rebound cycle and define focus, epicenter, and the difference between P, S, and surface waves

  • Explain how seismic station data locate an epicenter and how magnitude scales differ from intensity scales

  • Classify folds and faults by geometry and stress, and distinguish hanging wall from footwall

  • Sequence the formation of a mountain belt from sedimentation through collision and isostatic uplift

  • Summarize the mantle-convection and slab-pull mechanisms that drive plate motion and note their relative importance

Your checkpoint

A written 300-word explanation of how a single convergent margin produces earthquakes, volcanoes, and mountains, with a labeled sketch, graded against a rubric you write first

Week 7

Applications

  • Classify the major fossil fuel and mineral resources by origin and describe the geologic conditions that concentrate them

  • Explain how geologic maps and cross-sections are used to site wells, tunnels, and landfills

  • Assess two geohazards (earthquake shaking, landslides, flooding, or volcanic ash) in terms of risk factors and mitigation

  • Interpret basic geophysical and remote-sensing data as applied to resource exploration or hazard mapping

  • Describe how groundwater contamination moves through an aquifer and outline a remediation approach

Your checkpoint

A two-page applied case study choosing one region and one resource or hazard, integrating at least three geology concepts from earlier weeks

Week 8

Core knowledge & Surface processes & Tectonic earth processes & Applications

  • Retrieve core definitions across all four domains from memory in a timed drill

  • Re-teach your three weakest topics aloud or in writing without notes

  • Work through missed questions from earlier weeks and record the underlying concept, not just the correct answer

  • Take two full-length timed practice tests and compare scores by domain

  • Finalize a one-page formula-and-terms sheet covering gradients, half-life, and key vocabulary

Your checkpoint

Two timed practice test scores logged by domain, plus a corrected error log showing the concept behind every miss

Milestones

Week 2: Score at least 80% on your self-written rock classification and dating quiz, and correctly classify 10 unknown rock specimens or descriptions without notes

Week 4: Complete the topographic-map exercise with correct gradient units and a drainage divide drawn in the right place; explain in one paragraph why a storm hydrograph peaks later downstream

Week 6: Draw and label all three plate boundary types from memory, including stress, fault type, seismic signature, and one real-world example each, with no more than one error

Week 8: Reach at least 75% on both timed practice tests and show a written error log where every missed question is tied to a specific concept and a corrective action
