Minerals
Minerals are identified by these.
What are mineral properties?
A solid material made up of one or more minerals.
What is a rock?
The center of the earth, made mostly of solid iron and nickel.
What is the inner core?
The type of volcano that has gently sloping sides.
What is a shield volcano?
Waves generated by an earthquake.
What are Seismic waves?
Define mineral lustre.
What is the way a mineral shines, or reflects light?
Metamorphic - Example Marble and Gneiss (nice).
What are rocks that form when existing rocks are changed by extreme heat and pressure?
True or False; the tectonic plates are composed of 2 types of lithosphere; thicker continental and thin oceanic.
What is true?
Name of the area around the Pacific Plate where most of the earths volcanoes exist.
What is the Ring of Fire?
The location on the earths surface directly above where the earthquake occurred.
What is the epicenter?
The measure of how easily a mineral can be scratched.
What is hardness?
Rock that forms when melted, or molten, rock from deep below Earth's surface cools and hardens.
What is an igneous rock (Basalt, Obsidian)?
Define plate boundary.
What is the location where 2 plates meet?
The depression (bowl) at the top of a volcano.
What is a Crater?
This device must be attached directly to bedrock.
What is a seismograph?
The scale that lists the hardness of the ten common minerals.
What is the Mohs scale?
The preserved remains of a plant or animal that lived long ago.
What is a fossil?
This type of heat transfer moves heat from the mantle to the crust.
What is convection?
Occurs in areas where plates (crust) are thin and the mantle temperature is much hotter than normal. The hotter magma rises and can be forced up through the cracks in the crust.
What are hot spots?
The 3 types of faults and the plate boundaries they occur at.
What are a Normal fault – at divergent boundaries, a Reverse fault – at convergent boundaries, a Transform fault – at transform boundaries.
The color of a mineral when it is ground to a powder.
What is streak?
Sedimentary rocks are formed by these processes.
What are cementation and compaction.
The mountain range created by the divergent boundary in the Atlantic Ocean is called this.
What is the Mid-Atlantic ocean ridge?
Name the types of Tephra.
What are Volcanic dust, Ash, Lapilli and volcanic bombs?
The slowest seismic waves that do the most damage.
What are surface waves?
