what are the geomorphic processes
weathering (chemical, biological, mechanical)
erosion (hydraulic action, abrasion, solution, attrition)
mass movement (sliding, slumping, rock falls)
transport (solution, saltation, traction, suspension)
deposition
what are concordant coastlines
where the bands of resistant and non-resistant rocks are parallel to the sea
what are discordant coastlines
where the bands of resistant and non-resistant rocks are perpendicular to the sea
create headlands and bays
how do stumps occur
crack in resistant rock is made through a weakness in the rock and hydraulic action
the crack forms into a cave through hydraulic action
cave forms into an arch from further hydraulic action
the arch forms into a stack through chemical weathering
the stack forms into a stump through more chemical weathering - hydraulic action can also play into it
what is a spit
formed through longshore drift at the end of a coastline.
can curve from strong winds and waves - makes a sharp bend
mudford spit
what is a bar
formed when a spit joins 2 headlands together
cutz bay from the sea
creates a lagoon
made from longshore drift and prevailing winds
tombolo
formed when a spit joins to another island creating a ‘bridge’ between the two
chesil beach
What is the natural greenhouse effect?
The natural greenhouse effect is the process by which certain gases in the Earth's atmosphere trap heat, preventing it from escaping into space and thereby keeping the planet warm enough to support life.
What are the causes of natural climate change?
Sun Spots: Variations in solar radiation due to the number of sunspots affect Earth's climate.
Volcanic Eruptions: Eruptions can release ash and sulfur dioxide into the atmosphere, cooling the planet temporarily.
Milankovitch Cycles: These are long-term changes in Earth's orbit and tilt that affect climate patterns over thousands of years.
