Name three types of rocks, give three examples.
Igneous: Granite, Basalt, and Pumice.
Sedimentary: Limestone, Sandstone, and Shale.
Metamorphic: Marble, Slate, and Gneiss.

Name and define the properties of minerals.
Color: Minerals come in many colors.We can't always identify minerals by color because the same mineral can come in many colors.
Lustre: Lustre is the reflection of light from the surface of a mineral. If a mineral looks shiny, it has a metallic lustre. If not shiny, it has a non-metallic lustre.
Hardness: The hardness of a mineral can be an important clue to it's identity.
Transparency: The transparency of a mineral describes how well light passes through it.
Magnetism: Some minerals are attracted to magnets. Hold a magnet on a string close to a mineral. If the magnet is pulled toward the mineral is magnetic.

They have been turned into a Butchart garden and swimming pool.

How does the rock cycle work?
Rocks go through a continuous cycle of change. Igneous rocks are made when lava or magma hardens into rock. When the rock is exposed to air, erosion begins. Almost immediately, wind and rain weather the rocks and cause them to erode into sediment. The sediment becomes sedimentary rock. This rock is often buried beneath the Earth’s surface, where it may become metamorphic rock. If the metamorphic rock is near magma, it may melt to become igneous rock. This process is known as the rock cycle.
