Past tectonic process in the development of upland and lowland landscapes Flashcards
What is the earth’s outer layer known as
The Earth’s crust
How is the earth’s crust divided
Into a number of moving tectonic plates
What happens when the plates move away from each other
New crust (land) is created
What is the Mid Atlantic Ridge
The plate boundary separating the Eurasian plate and the North American plate
What is happening at the Mid Atlantic Ridge
The plates are moving away from each other and so new crust is being created , spreading the ocean floor
Why is there igneous rock in the UK even though it doesn’t have any volcano
Millions of years ago the UK was much closer to the Mid Atlantic Ridge and so would have experienced volcanic eruptions.
What is found at plate boundaries
Many active volcanos
What did the plate movements cause
Massive folds and faults in the rock
