Subjected to the pressures and heat within the earth, one kind of rock can transform into something new. These are metamorphic rocks, which after magmatic rock is another of the three kinds of rock.
Sedimentary rocks are the most common kind of rocks, created by eroded rock particles that are collected, compacted, and cemented together into new rock. In short, what was once sedimentary rock and is now sand will one day again be sedimentary rock.
Some of the world's most famous buildings have sedimentary rock as part of their construction. This museum and Parliament Hill join structures like Petra in Jordan, and the Egyptian pyramids, in consisting of sedimentary rock.
A video monitor looks at sedimentary rock landscapes. We'll pick up here tomorrow.
