Topic 4: The UK’s evolving physical landscape Flashcards
Revision for 8th November 2021. - UK Physical landscapes, including, landscapes you find in the UK, interactions between humans and the landscapes.
Rock types - What are the location, features and characteristics of Sedimentary Rock?
Made from grains or ex-living things. After being eroded and transported, they are deposited. Sedimentary rocks are porous and permeable.
Location - Younger is formed around London and Older is formed in Nottingham.
Rock types - What are the location, features, and characteristics of Igneous Rock?
•formed from magma and lava (molten rock) cooling and becoming solid.
•can be made below surface as intrusive rocks or above as extrusive rocks.
•largely impermeable.
Location - Mostly found in Scotland, parts of Ireland and in South West England (including dartmoor)
Rock types - What are the location, features, and characteristics of Metamorphic Rock?
•Metamorphic rocks are usually hard.
•They may contain tiny crystals
•Igneous and sedimentary rocks beneath the surface can be subject to intense heat and pressure which can change them into metamorphic rocks.
•Metamorphic rocks were once either igneous or sedimentary.
Location - main part of Scotland and most of wales
What is a sedimentary rock like and how is it formed?
Crumbly, porous, and formed by layers of minerals deposited on the seabed, then squashed together to form rock.
What is an igneous rock like and how is it formed?
Very hard, contains crystals and formed by magma cooling and forming rock.
What is a metamorphic rock like and how is it formed?
really hard, contains crystals - these rocks used to be sedimentary or igneous. formed under intense heat and pressure under ground.
What are some examples of sedimentary rock?
Limestone, sandstone
What are some examples of igneous rock?
Granite, basalt
What are some examples of metamorphic rock?
Marble, serpentine
Remember exam-style structure
(1 mark) One sentence - make a statement and keep it simple.
(2 marks) Make one point and expand on it / extend it / explain it once.
(3 marks) Make one point and expand on it twice.
What does topography mean?
The shape and height of the land. - Can also be described as relief.
Describe the relief of the UK (4 marks) - review
The relief of Britain varies from lowland in the South East and central England, where you will find the land is largely between 50 and 100 metres above sea level.
However, the landscape (relief) gets higher as you go North (North West). The mountain areas cover all of Wales, Scotland and Northern England. Some of the highest areas in Scotland are over 600 metres above sea level.
Why does the relief in the UK vary? - Upland
Upland areas in the north and west are high and generally hilly because they are HARD rock.
What does that mean?
This means they are more erosion resistant, either metamorphic or igneous. They get higher the further north you travel.
Why does the relief in the UK vary? - Upland (2)
Many upland areas have been created due to plate tectonics.
