Factors Affecting Coastal Processes Flashcards
what are the three factors that affect coastal processes?
Aspect, climate and geology
what is the definition of aspect?
The direction, of coastline or slope faces
what is aspect tend to link to?
Fetch and prevailing winds
What is the definition of climate?
Atmospheric conditions of an area
what are microclimates?
Localise climates
what can high temperatures mean?
Stronger chemical weathering, more warm air moves towards the sea, more biological weathering, more air rising which creates more winds
what can lower temperatures mean
more physical weathering, more chemical weathering ONLY CARBONATION
what can high amounts of precipitation mean
more rain means more mass movement, mkre surface run off means more material can be easily transported from cliffs,
what does low amounts of precipitation mean
more physical weathering, more dry movement of material
what can high wind speeds mean
high energy waves which leads to more erosion, more cooling effect on temperature
what can low wind speed mean
more deposition of waves that have less energy, temperature may increase which leads to more chemical weathering
what can rock type determine?
How slowly or quickly the rock can be worn away
describe igneous rocks
Formed deep within the Earth and have a volcanic origin as they are formed from magma, be a crystalline, which means that made up of interlocking crystals, this mixing resistant to weathering and erosion
what are some examples of igneous rocks?
Granite and basalt
describe sedimentary rocks
From from deposited sediments that have been consolidated over many years, the formed in layers called beds or strata
