    Igneous rock landscape

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

    ISLA: Traprain Law is an unusual igneous intrusion called a laccolith.

    Igneous intrusions form when molten rock, or magma, from deep underground pushes up towards the Earth’s surface but cools and solidifies before it gets there.

    Some magma is super thick, so it can only force itself a short distance, sideways into a mushroom shape, pushing up the rock above before solidifying.

    CONNOR: Just like at Edinburgh and Castle Rock!

    ISLA: Yes, they’re all connected - part of the same volcanic mountain range.

    CONNOR: Well that’s interesting, and almost as much fun as climbing them.

    Come on!

    ISLA: Wow, that was hard work, but worth it for the view!

    CONNOR: Look how flat the rest of the land is - it’s really fertile and good for farming.

    ISLA: And look at the wildflowers!

    So beautiful. The fertile land must be why they grow so well.

    CONNOR: Look over there, Isla, an Exmoor pony. They come all the way from the moors in Devon and Som
