Rocks at the Royal National Park
Rocks at the Royal National Park
Most of the rock in the Royal National Park (and throughout Sydney) is sedimentary rock.
The main type of sedimentary rock you will see when visiting the Royal National Park is called Hawkesbury Sandstone. If you're from Sydney, your home and school are probably built on Hawkesbury Sandstone. It formed approximately 200 million years ago - when dinosaurs were roaming the Earth!
Other sedimentary rocks you might see while in the Royal National Park are shale and conglomerate.
sandstone
made up of sand particles
shale
mixture of small clay and sand particles
conglomerate
various sized particles cemented together from a grain of sand to pebble
