Freeze- thaw weathering is when water in cracks of the rock freezes then expands and controls repeatedly weakening the joint until jaggy rock fragments break of.
Plucking is when the glacier freezes onto loosened rock and rips/pulls it free as the glacier moves.
abrasion is when the loosened rock is embedded in the ice and scraped the hallow as the glacier moves.
Arete
It is a knife edge ridge and is formed when two neighbouring forties run back to back. As each glacier erodes either side of the ridge, the edge becomes steeper and the ridge comes narrow.
Glaciation processes
there processes make corries sit back to back and as the glaciererodes backwards into the mountain, the corroded get bigger forming a knife edge ridge called an arête. Freeze- thaw weathering is when water gets into cracks into the rock meaning the ridge is more jagged.
U- shaped valley.
Snow falls in an existing U-shaped valley and the bottom layer turns to ice. As the ice moved it erodes the valley base. The bottom layer of ice moved downhill and eroded the valley. Plucking is when the glacier freezes onto loosened rocks and rips/pulls them free as it moves. Abrasion is when rocks embedded in the base of the glacier scour the valley floor. After the glacier retreats, a steep sided U shaped valley with a wide, flat valley flood is left behind. if has steep. Valley sides and wide, flat valley floor.
Pyramidal peaks
Formed when 3 or more corries out backwards into the same mountain. Snow accumulates and turns into ice, moved and eroded hallows. Plucking is when the glacier freezes into loosened rock and rips/ pulls it free as the glacier moves. The glacier erodes backwards into eachother.
Abrasion
Is when the loosened rock and is embedded in the ice scrapes the gallows as the glacier moves. 3 sharp acts are created to make a pyramidal peak. freezethaw weathering erodespeach and makes it more jagged.
What is a glacier system?
Inputs come from avalanches along the side of the glacier but mainly from precipitation as snow. Overtime snow accumulates and is compressed into ice. The water held in storage is the glacier. Under the force of gravity, the glacier flows downhill. Melt water is the main output from the glacier, along with some evaporation.
Sites for development
Settlements: a place where polemic live (workers/ customers)
Accessibility: roads on foot, train, bus, boat, bike, horses for deliveres, construction workers, general workers and construction workers.
Land use conflicts/ loch lomond
Tourists vs tourists
Water sports- sightseers/ fisherman/ noise from engines scare fish away.
Use of boats on the loch- pollution of water/ erosion of banks.
Tourists can cause footpath erosion- walkers not sticking to path and being overused.
land use conflicts/ loch Lomond
Tourists vs farmers
Leave gates open- animals escape and potentially get injured.
Hill walkers could trespass- destroy farmers crops/ lower yield.
Let dogs of leads- could chase or scare farm animals(sheep)
Drop litter- animals could eat and choke (potentially die)
Pack cars next to gates- farmers machinery cant get in.
Climb over walls- causing them to break and farmers need to fix them.
land use conflicts
Tourists vs locals
Visit by car- park illegally (Narrow streets) leading to traffic congestion.
Dropping litter leaving BBQs- ruins scenery, and wild life can also eat it.
But holiday home- if this only used occasionally in the year/town can develop.
Staying in campsite nearby- noise pollution disturbing locals sleep.
