Flashcards in L1 - Home of the Hogwarts Deck (8)
How are igneous rocks formed?
When volcanoes erupt and the magma/lava cools.
How are metamorphic rocks formed?
A morphed version of another rock due to extreme pressure and heat (usually at subduction/collision zones)
Comprises of layers of rock (e.g. shale, schist)
How are sedimentary rocks formed?
Deposition of particles that have been eroded, also remains of plants and animals. E.g. chalk
What are the characteristics of the rock type(s) found in the UK Uplands?
Igneous and metamorphic rock due to magma rising through Earths crust (high relief area e.g. Dartmoor)- resistant to erosion
Scotland, Wales, SW England
What type of rock is the majority of the UK?
Sedimentary - long time since UK was near a plate boundary
Formed when the UK was near tropical seas and plants and animals died (carboniferous limestone)
State the 2 processes that wear down mountains (via glaciation).
What is plucking?
Rocks and stones are frozen on the sides of glaciers, when the glacier moves they get plucked off leaving jagged surfaces.
