PHYSICAL
LANDSCAPES
IN THE UK
- UK Physical
Landscape
- RELIEF = the height,
steepness +shape of the
landscape. = determained
by geology
- LANDSCAPE = result from
the interaction between
natural / physical factors
- IN THE UK = N/W
= upland more
resistnat rock. =
S/E = lowland
weaker rocks.
- RELIEF = the height,
steepness +shape of the
landscape. = determained
by geology
- Coastal
Landscapes in the
UK
- Constructive / Destructive
- CONSTRUCTIVE WAVE = formed
by a storm often hundreds of
km away. common in summer
- DESTRUCTIVE WAVE = formed
by local storms close to the
coast. common in winter
- CONSTRUCTIVE WAVE = formed
by a storm often hundreds of
km away. common in summer
- How a wave is formed
- WEATHERING = the weakening /
decay of rock due to the actions
of weather, plants and animals
- MECHANICAL (physical) =
the disintegration of rock
- eg: Freeze-thaw
- eg: Freeze-thaw
- CHEMICAL = caused
by chemical changes
- eg: Carbonation
- eg: Carbonation
- BIOLOGICAL = caused
by the actions of
flora and fauna
- eg. plants roots
grow in rocks /
animals burrow into
weak rocks
- eg. plants roots
grow in rocks /
animals burrow into
weak rocks
- TYPES OF MASS MOVEMENT =
downward movement (sliding)
of weathered material and
rock
- Deposition - occurs when
water slows down and
waves lose their energy
- MECHANICAL (physical) =
the disintegration of rock
- COASTAL EROSION
- Solution - Dissolving of
soluble chemicals in rock
- Corrasion - rocks fragments picked
up by the sea are thrown at the cliff.
they scrape and wear away the rock
- Abrasion - the "sandpapering"
effect of pebbles grinding
over a rocky plateform
- Attrition - rocks fragments carried by the sea knock
against each other becoming smaller / more rounded
- Hydraulic action - the power of the waves as
they hit a cliff. trapped air is forced into cracks
in the rock, eventually causing it to break up
- Erosion Landforms
- Factor 1 = ROCK TYPE - some rocks are
harder / softer than other so easier to erode
- Factor 2 = GEOLOGICAL STRUCTURE - the way the rocks has
been folded / tilted. Faults (cracks) form lines of weakness.
- Factor 1 = ROCK TYPE - some rocks are
harder / softer than other so easier to erode
- Solution - Dissolving of
soluble chemicals in rock
- Transportation
- Longshore Drift - the movement depends
on the direction that waves approch the
coast sue to prevailing wind direction
- Deposition Landforms
- SANDY beeches - mainly found in sheltered
bays and are created by conservative waves
- Along high-energy coast sand is washed
away leaving behind a PEBBLE beech
- SANDY beeches - mainly found in sheltered
bays and are created by conservative waves
- Constructive / Destructive
- River Landscapes
