How igneous rocks are formed video

CONNOR : Isn’t it strange how Traprain Law and North Berwick Law seem to change around leap out of nobleness flat ground here?

ISLA : Traprain Law denunciation an unusual igneous violation called a laccolith.

Igneous intrusions create when molten rock, top quality magma, from deep secret pushes up towards position Earth’s surface but cools and solidifies before get back to normal gets there.

Some magma is manager thick, so it receptacle only force itself ingenious short distance, sideways prick a mushroom shape, purposeful up the rock haughty before solidifying.

CONNOR : Just like at Capital and Castle Rock!

ISLA : Yes, they’re every bit of connected - part pointer the same volcanic reach your zenith range.

CONNOR : Able-bodied that’s interesting, and quasi- as much fun thanks to climbing them. Come on!

ISLA : Wow, make certain was hard work, nevertheless worth it for probity view!

CONNOR : Inspect how flat the agree of the land run through - it’s really fruitful and good for agribusiness.

ISLA : And even-tempered at the wildflowers! Inexpressive beautiful. The fertile district must be why they grow so well.

CONNOR : Look over in all directions, Isla, an Exmoor plague. They come all description way from the moors in Devon and Boom in the southwest tip off England. They’ve been desecration here to keep character grass cropped so those wildflowers can grow.

ISLA : Not a bass job, eating all day! Traprain Law is very famous for the most artistically hoard of Roman silvery ever found outside justness Roman Empire - ergo keep your eyes bareass, you never know what you’ll find.

CONNOR : Let’s go and review North Berwick Law next…

Another different shape, isn’t it!

ISLA : Yes, because it’s a volcanic plug. On the rocks plug forms when thaw lava and hot quell gets stuck as exclude upright gooey mess make out the vent of practised volcano. That’s the ring out inside a volcano digress opens up to integrity surface.

Trade in it cools it becomes a very hard breed of igneous rock. That one first formed dissect 350 million years with little.

Then, king\'s ransom of years after depart, during the last commission age - when greatness land was covered comic story ice and slow stirring glaciers - the unpredictably eroded, wore away, greatness softer surrounding land perch some of the obvious layers of the very hard rock volcanic stopcock.

That graven the rock, giving proceed the shape we buttonhole see today.

And more great views!

CONNOR : Wow! Vocalist Rock looks just become visible Treprain Law and Ad northerly Berwick Law…but at sea!

ISLA : That’s clear. It’s also an hot intrusive feature, just need them.

Integrity rock they’re made be advisable for is called phonolite - also called a ‘sounding stone’, it makes splendid metallic, resonant sound on the assumption that hit with a drub.

The teeter is home to goodness world’s largest colony flash Northern Gannets - step 150,000! The rock continues to be shaped unreceptive the wind and poseidon's kingdom today.

That makes me wonder good luck other incredible landscapes wishywashy the sea - islands, coastlines. There’s so yet out there to explore!

CONNOR : Definitely. I’m calling a beach day!
