It came from outer space
This type of telescope uses lenses, is less expensive and is more durable.
What is a refracting telescope?
This is the scale to measure hardness
What is the Mohs Scale?
A rock that has a valuable mineral in it.
What is an ore?
Obsidian, pumice and scoria are examples of this specific type of igneous rock
What is volcanic glass?
This property of minerals is defined as the resistance to being scratched.
What is hardness?
This type of telescope uses mirrors and is more expensive and less durable.
What is a reflecting telescope?
This type of breakage results in smooth clean lines.
What is cleavage?
What is intrusive?
These rocks are formed from sediment being pressed together.
What are detrital sedimentary rocks?
This type of breakage results in jagged or rough edges
What is fracture?
Our sun is this type of star
What is a yellow dwarf?
This is how a mineral reflects light
What is luster?
Igneous rock that forms from cooled lava
What is extrusive?
This type of sedimentary rock is formed from mineral deposits.
What are chemical sedimentary rocks?
The theory that the moon came from a piece of early Earth that was knocked off by a passing asteroid.
What is the impact theory?
The dark regions of the moon, caused by asteroid impacts.
What is maria?
The color of a mineral in powder form after it is dragged across a non-glazed piece of porcelain.
What is streak?
The model we use to describe how rocks change from one type to another.
These types of metamorphic rocks have noticeable parallel bands, meaning they look like a 'rock lasagna'.
What are foliated rocks?
This theoretical star will exist when a white dwarf fully cools down.
What is a black dwarf?
This is the result of a star not gaining enough mass and not starting fusion. (This is a failed star)
What is a brown dwarf?
These are the four parts of the definition for 'mineral'
What are naturally occurring, inorganic, definite chemical composition, and orderly arrangement of atoms?
This is formed from completely melted and cooled rocks
These sedimentary rocks are composed of things that were once living.
What are organic sedimentary rocks?
This is how the sun produces energy and heat. This process shoves atoms together hard enough to combine them
What is fusion?
