As you look out from this stop you will see the beaches of Awenda are littered with rocks of all different shapes, colours and sizes. The amazing thing about them is that almost all of them were transported here from the Canadian Shield by the Laurentide Ice Sheet and dropped 12,000 years ago with warming temperatures.
Some of the rocks you may find along Awenda’s beaches include igneous, metamorphic and sedimentary rocks.
Take the Igneous Challenge:
Igneous rocks form when molten magma solidifies and cools. This can occur deep underground, which is a slow process that allows large crystals to grow and form intrusive igneous rocks. Rapid cooling at the surface forms very fine crystals and extrusive igneous rocks.
Granite is a type of intrusive igneous rock which contains larger grain sizes. They are typically lighter in colour and lack an alignment of grains within the rock.
As you walk find an example of an igneous rock. How common are these volcanic beauties?
