Crust, Mantle, and Core
What are the divisions based on LAMOI and the Crust, Mantle, and Core
Lithosphere - makes up the crust and the top of the Mantle Asthenosphere and Mesosphere - make up the Mantle Outer Core - makes up the outside of the Core Inner Core - Makes up the inside of the Core
How does pressure, density, and temperature vary with depth
The further you go down the more the pressure, temperature, and density increase
What makes a mineral a mineral.
Solid - A definite volume and shape Naturally occurring - Created by natural processes Crystal structure - Particles that line up in a repeating pattern Forms by inorganic - Formed from materials that were not living things Definite chemical composition - Contains the same element in defined proportions
What is the mineral property that describes the color of powder produced by a mineral
Mineral streak
What is the mineral property that describes how a mineral breaks cleanly
Mineral Cleavage
What is the mineral property that describes how a mineral breaks unevenly
Mineral Fracture
What is the mineral property that describes how a mineral reflects light
Mineral Luster
How does convection work
Convection is when warmer less dense material rises causing it to become denser and cooler making it fall, starting a cycle
What properties does convection rely on.
Convection relies on the fact that the material’s density changes whenever it gets hotter or cooler.
How do you calculate density
Mass divided by volume (mass in the numerator and volume is a denominator)
What is density
Mass packed/squished into a given amount of space
