Light & Color 1
Any surface that reflects light
What is mirror?
The three primary light colors
What are blue, green, and red?
A naturally occurring, inorganic solid with a crystal structure and a definite chemical composition
What is a mineral?
The five Earth layers
What are the crust, upper mantle, lower mantle, outer core, and inner core?
Term that means "the strength of an earthquake"
What is magnitude?
Objects that produce and give off their own light, such as the Sun
What are luminous objects?
The color that results when the three primary pigment colors are mixed equally
What is black?
The scale used to describe mineral hardness
Rigid slabs of rock that Earth's crust is made of
What are plates?
The point where an earthquake starts, usually below Earth's surface
What is the focus?
Objects that give off light that they do NOT produce, like the Moon
What are illuminated objects?
Type of reflection that forms an unclear image when light bounces off a rough surface
What is diffuse reflection?
The process that forms rock from sediment
What is lithification?
The three types of plate boundaries
What are convergent, divergent, and transform?
Type of volcano that is a crack in Earth's crust, expels large amounts of lava, and has no central crater or volcano-like features
What is a fissure volcano?
Energy from a light wave is transferred to the medium through which it traveled
What is absorption?
A mirror that curves inward like the inside of a spoon
What is a concave mirror?
The process that forms metamorphic rock from a parent rock
What is metamorphism?
Process that occurs in the lower mantle and causes tectonic plates to move (like a conveyor belt)
What is mantle convection?
Type of seismic wave that is the slowest and most damaging
What is a surface wave?
Light passing through a material
What is transmission?
A measurement of how quickly or slowly light moves and how much light changes direction in a transparent material
What is an index of refraction?
The series of processes that continually change one rock type into another
What is the rock cycle?
The name of the proposed supercontinent that all continents were once part of
What is Pangaea?
Type of volcano that is a small, steep-sided cone with a bowl-shaped crater at the top, formed from lava ejected from a volcanic vent
What is a cinder cone volcano?
