Before taking the test
- —Know the difference between endogenic forces (interior - earthquakes, volcanoes) and exogenic forces (surface - weathering, erosion)
- —Remember: a volcano is a vent (opening) in the earth's crust through which molten material erupts suddenly
- —Focus = underground origin of earthquake; Epicentre = surface point above focus
- —Weathering = breaking of rocks (no transport); Erosion = wearing away + transport by water, wind, ice
- —River journey: Waterfall → Meanders → Oxbow Lake → Floodplain & Levees → Distributaries & Delta
- —Coastal erosion sequence: Cracks → Sea Caves → Sea Arches → Stacks → Sea Cliff; Beaches are depositional
- —Glaciers erode by bulldozing (create hollows/lakes) and deposit glacial moraines
- —Wind creates mushroom rocks (erosion), sand dunes (heavy sand nearby), and loess (fine sand carried far - found in China)
- —Don't confuse: tributaries (join river) vs distributaries (branch from river); magma (inside) vs lava (outside)
- —Know earthquake safety: shelter under table/desk, away from windows/mirrors, spread awareness
Key Concepts to Remember
Earth's Forces
Endogenic (inside): Earthquakes + Volcanoes; Exogenic (outside): Weathering + Erosion (by water, wind, ice)
River Landforms
Waterfall → Meanders → Oxbow Lake → Floodplain & Levees → Distributaries → Delta
Coastal Landforms
Erosion: Sea Caves → Sea Arches → Stacks → Sea Cliff; Deposition: Beaches
Wind Landforms
Erosion: Mushroom Rocks (narrow base, wide top); Deposition: Sand Dunes (nearby) + Loess (far away, China)
