affect the landscape
geology
tectonic processes
glaciation
upland areas
hard rock
- igneous
- metamorphic
- (some) sedimentary
lowland areas
soft
-sedimentary
igneous rock
(resistant)
formed from lavas and deep nagana once molten then cooled and crystallised
igneous example
granite
basalt
sedimentary
(least resistant)
formed form sediment eroded and deposited
sedimentary example
chalk
clay
sandstone
metamorphic
sedimentary rocks that were heated and compressed during igneous activity
metamorphic examples
slate
marble
tees-exe line
separates upland and lowland
north =hard
south =soft
yorkshire dales
-limestone on valley = good building stone -rocks and boulders left by rivers of melting glaciers -dry stone as field boundaries -improve land for farming
east anglia
low lying
sands and clays (deposited by glaciers)
produce fertile soil for farming
hedges used for field boundaries
discordant coats
strata =right angle to coast
soft rock= eroded
hard rock= stays
concordant
strata=parallel to coast
hard rock= small crack
soft rock= eroded lots
hard rock= stops eroding
weakness in rock structure
joints
faults
