Canada's Rocks

Canada is a big, beautiful country filled with many geological scenes. From coast to coast we have harbours, plains, plateaus, and mountains. Rocks in mountainous regions and other areas are from one or more of the three basic rock types: igneous, sedimentary, and metamorphic.

Igneous Rocks

The dictionary tells us that igneous means of fire and heat. Igneous rocks were formed from volcanoes, lava, or magma. The lava and magma come from molten rock. Molten rock means rock that is melted. Lava is molten rock that is on top of the Earth's surface. Magma is molten rock that is still beneath the Earth's surface.

Molten rocks that have cooled and become solid are called igneous rocks.
