a planet made up of rocks and metals, with a hard surface and a molten core. The four terrestrial planets in our solar system are Mercury, Venus, Earth, and Mars
Compound
refers to the mineral that has two or more substances formed together
Non-Silicates
group of minerals that do not contain silicon oxygen tetrahedra as basic building block . Groups are carbonates, oxides, sulfides, sulfates, halides
Polymorph
A mineral which has the same chemical composition as another mineral, however their atoms are arranged differently; subsequently, have very different properties
Solid-State Diffusion
process where atoms or ions move through a solid material
Batholith
a large mass of intrusive igneous rock that forms deep within the earths crust, composed of granite or similar types of rock
Decompression
process in which a decrease of pressure with a constant temperature makes a rock melt
Effusive Eruption
steadily flows out of volcano in eruption
Pahoehoe
Lava flow form extremely hot basalt that forms with a skin that is rolled into smooth ropy ridges
Sheen
smooth shiny surface that develops due to metamorphism, weathering or abrasion.
Solid-state Change
when rocks are subject to high temperature and pressure, they can undergo solid state changes that lead to the formation of new minerals or changed in the arrangement of existing minerals. E.g. shale can transform into schist or slate.
Amber
body fossils can be preserved in it. Sap or resin
Cretaceous-Paleogene (K-Pg) Extinction
meteorite that wiped out dinosaurs
Inclusions
objects enclosed in rock are older than the rock itself
Moho Line
the boundary between the earths crust and mantle. Marks a sudden change in seismic wave speed
Fjord
u shapes glacial troughs flooded by the sea
Distilling
purifying a liquid by heating until it turns to Vapor
Ductile
refers to the ability of a metal to withstand stress without rupturing, stretched into thin wires
