Down Under
These large chunks of crust move around on top of the mantle.
What are tectonic plates?
This type of rock can be found in old lava flows.
What is igneous?
This property of minerals relates to how easily they are scratched or dented.
What is hardness?
These explosive mountains are the archetypal volcano.
What are stratovolcanoes?
This natural energy form is impossible for us to capture.
What is lightning?
This substance is molten or melted rock deep underground.
What is Magma?
These rocks are common on the surface but rare deep underground.
What are sedimentary rocks?
Only minerals containing iron, nickel or cobalt tend to have this property, which is useful for navigation.
What is magnetism?
Found throughout the Hawaiian islands, these wide volcanoes produce more lava and less explosive gases.
What are shield volcanoes?
A renewable energy that requires access to rivers.
What is hydroelectricity?
Heat from this central part of the planet keeps the mantle molten.
What is the core?
Often found near volcanoes or faults, these rocks do not fully melt.
What are metamorphic rocks?
These two properties, though linked, often have different results for the same mineral.
What are streak colour and crystal colour?
This watery disaster accompanies oceanic earthquakes.
What is a tsunami?
Incredibly flammable and energy dense. These three fuels come from ancient dead organisms.
What are fossil fuels (Gas, Oil & Coal)?
The layer of the Earth that we live directly on.
What is the crust?
The very bottom of the crust is made of cooled magma, resulting in these rocks.
What are igneous rocks?
This characteristic of minerals is what excludes obsidian and glass from counting as minerals.
What is crystal structure?
Found far from plate boundaries, these volcanoes often form islands in the middle of the ocean.
What are hot spot volcanoes?
Though often politicized this energy source can be found and used around the world, and has been for hundreds of years. So long as the weather permits.
What is wind?
This type of fault is associated with earthquakes but not volcanoes.
What are transform faults?
Individual crystals within a rock are examples of this kind of substance.
What are minerals?
This scale places diamonds at a 10 with talc at a 2.
What is the mohs hardness scale?
This fast moving gas and dust cloud destroyed the city of Pompeii and is the most dangerous part of a stratovolcano.
What is a pyroclastic flow?
Most energy sources are just a roundabout way to harness this type of energy.
What is solar energy?
