WJEC A-Level Geology

Notes and diagrams explaining the processes of metamorphism - both regional and contact - as well as the rocks produced by each. Includes how to describe the metamorphic rocks and create thin section drawings.

Extensive notes and diagrams explaining the structure and composition of the earth, the evidence for this, mineral identification, plate tectonics and the mechanisms for their movement, plate boundaries and the landforms formed at them.

Detailed notes and diagrams explaining igneous rocks and textures, the structure of oceanic crust, igneous structures, absolute dating and volcanoes (hazards, prediction and monitoring)

Detailed notes and diagrams explaining weathering and erosion, the Hjulstrom Curve, sedimentary rock descriptors, sedimentary structures, key facies in sedimentary, fluvial and marine environments, and the process of diagenesis

In depth notes and diagrams about weathering and erosion, triangular graphs, desert and fluvial environments, deltaic systems, turbidity currents and turbidites, limestone formation, and diagenesis

Descriptive notes explaining the fossil record, lagerstatten, evolutionary trends, evolution of vertebrates, mass extinctions, global climate, evidence for past climates, the influence of greenhouse gases, tectonics and volcanoes on the environment, and the Anthropocene.

In-depth notes explaining the generation of magma at divergent boundaries, intraplate settings (hotspots) and convergent boundaries, the generation of granite, advanced radiometric dating, igneous bodies and igneous processes

Notes describing factors affecting rock behaviour, principal stress orientations of different types of faults, fault indicators, folding mechanisms, cleavage-bedding relationships, fault reactivation, and interpreting block diagrams and maps

In-depth notes describing factors controlling metamorphic processes, metamorphic environments (dynamic, burial, contact and regional), chemical equilibrium changes during metamorphism, metamorphic structures and textures and pressure-temperature-time graphs

Extensive notes explaining the environments, formation, extraction, prospecting techniques, hazards and environmental considerations of coal, hydrocarbons, metallic ores, igneous associations, sedimentary associations and non-metallic minerals

In-depth notes explaining stress-strain graphs, factors affecting stress and strain, unconformities, folding, and faults (dip-slip and strike-slip)

Extensive notes explaining the types of seismic wave, elastic rebound theory, Mercalli and Moment Magnitude Scales, effects of an earthquake, factors affecting the risk of damage to property and loss of life, earthquake precursors, geohazards, seismic risk and return period, and earthquake and tsun...

In-depth notes explaining porosity and permeability (and the factors affecting them), types of mass movement, mechanisms and triggers for mass movement, monitoring techniques and methods of controlling mass movement

In-depth notes explaining groundwater supply, Darcy's Law, problems with over extraction of groundwater, water quality and groundwater pollution, and waste disposal
