Up land and low land landscapes Flashcards
What are the two geological halves of the UK?
Northwestern UK is mainly hard igneous rocks; Southern UK is mainly softer sedimentary rocks
This division influences the physical landscapes of the UK.
What type of landscapes do igneous rocks form in the UK?
Upland landscapes
These landscapes are found in the northwestern part of the UK.
What type of landscapes do sedimentary rocks form in the UK?
Lowland landscapes
These landscapes are prevalent in the southern part of the UK.
How did plate tectonics influence the UK’s geology?
Plate movements caused mountains, huge folds, and faults in the rocks
This tectonic activity has shaped the physical landscape of the UK.
What significant geological event occurred 520 million years ago in the UK?
Two plates converged to form upland mountain landscapes
This event affected regions such as northern Scotland, the Lake District, and North Wales.
What happened 50-60 million years ago related to plate boundaries?
Diverging plate boundaries caused the Atlantic Ocean to open
This event was significant in shaping the geology of the UK.
What geological feature was produced by rising lava at the Giant’s Causeway?
Distinctive basalt geology
The cooling of lava into polygon shapes is a characteristic of this region.
What type of rocks are associated with the tectonic events in the northwestern UK?
Igneous rocks formed from magma and lava
This is linked to long-extinct volcanoes that created hills and mountains.
Fill in the blank: North west of the Tees-Exe line, the UK’s geology is largely _______.
igneous rocks
This geological characteristic influences the landscape.
What are examples of distinct landscapes formed by basalt?
- Giant’s Causeway in Northern Ireland
- Fingal’s Cave in Scotland
These formations are a result of the cooling of lava into distinctive shapes.
