Lithosphere, Rocks and Soils
Rock and mineral resources, weathering, soil formation, soil properties, degradation and restoration.
How to study A-level Environmental Science
Move from process and system knowledge to quantitative evidence, field and laboratory method, uncertainty, environmental trade-offs and sustained conclusions.
Core concepts
Concept 1
Parent material, climate, organisms, topography and time influence soil development.
Exam cue: Identify the scope and evidence that control the lithosphere, rocks and soils decision before selecting a rule or method.
Concept 2
Soil structure, texture, organic matter and chemistry affect productivity and vulnerability.
Exam cue: Connect parent material, climate, organisms, topography and time influence soil development. with soil structure, texture, organic matter and chemistry affect productivity and vulnerability. and test the conclusion against extraction and land management create trade-offs that should be evaluated across the resource life cycle..
Concept 3
Extraction and land management create trade-offs that should be evaluated across the resource life cycle.
Risk pitfalls and guardrails
Applying a neighbouring topic or route rule without checking whether it belongs to Lithosphere, Rocks and Soils.
Guardrail: Check the current official source, route and assessment boundary before relying on a memorised rule.
Memorising a label or number without being able to interpret evidence, explain the boundary or apply the method.
Guardrail: Check the current official source, route and assessment boundary before relying on a memorised rule.
