Minerals
Rocks
Earthquakes
Volcanoes and Mountains
Crust
100
A pure, naturally ocurring, inorganic, solid substance.
What is a mineral?
100
These are the three rock families (classifications).
What is igneous, sedimentary, and metamorphic?
100
We measure earthquakes using this scale.
What is the Richter scale?
100
A volcano is described as this.
What is an opening in the Earth's crust?
100
This is the name for the center of the Earth.
What is the core?
200
When describing this property, we say a mineral can be shiny, dull or metallic.
What is lustre?
200
These types of rock are often made in lakes and oceans where sediment settles.
What is sedimentary?
200
Most earthquakes in North America happen on this coast because it is near a plate boundary.
What is the West Coast?
200
Volcanoes occur at convergent and divergent boundaries and also where plates are this.
What is thin?
200
This is the layer we live on and is the only layer capable of supporting life.
What is the crust?
300
When examining this property, you may be surprised that it does not always match the mineral's colour.
What is streak?
300
This type of rock results from heat and pressure or hot fluids changing one type of rock to another. (example: limestone to marble)
What is metamorphic?
300
The energy waves that travel out from the focus and epicentre of an earthquake.
What are seismic waves?
300
Ash from a volcanic eruption can be dangerous, but it can also be beneficial. It can be beneficial by adding this to the soil.
What are nutrients?
300
Wegener's continental drift theory helped to develop this new, modern theory about crustal plate movements.
What is plate tectonics?
400
This is the least reliable property used to identify minerals.
What is colour?
400
The process by which rocks change by being heated up, cooled down, worn away and placed under pressure.
What is the rock cycle?
400
This is a break in rock layers and can be produced at divergent, convergent, or transformed boundaries.
What is a fault?
400
Mountains are formed by these three methods.
What is folding, faulting, and volcanic eruptions?
400
This is the theory that states that the Earth's crust is constantly moving and broken up into pieces called plates. These plates include not only the land above the ocean, but also the ocean floor as well.
What is plate tectonics?
500
The cleavage of a mineral is described as a split along smooth lines. This type of split is described as rough and jagged.
What is fracture?
500
Metamorphic rock must be melted and turned into this before changing to igneous rock.
What is magma?
500
Earthquakes happen at convergetn boundaries when plates to this.
What is push together?
500
These two things occur when plate boundaries move which cause folding and faulting.
What are heat and pressure?
500
This phenomenon is used to explain one theory behind plate movements. It involves hot magma in the lower mantle moving upward after it is heated by the intense heat of the earth's core. Once it is cooled again, it sinks back down into the mantle. The rising and sinking of the magma could cause the plates to move along with it.
What is convection currents?
