Earth Science Unit 2 Vocabulary

TermDefinition
Igneous Rocks formed by magma and lava as it cools
Metamorphic Rocks formed from other rocks under extreme heat and pressure
Sedimentary Rocks formed when sediments are compressed and/or cemented together over time and become a rock
Intrusive formed when magma penetrates existing rock, crystallizes and solidifies underground to form intrusions
Extrusive hot magma from inside the earth flows out onto the surface as lava or explodes violently into the atmosphere to fall back as pyroclastics or tuff
Compaction
Cementation process of sedimentary rock formation that occurs when dissolved minerals precipitate out of groundwater and either a new mineral grows between the sediment grains or the same mineral grows between and over the grains
Foliated metamorphic rock, such as schist or gneiss, whose minerals are squeezed under high pressure and arranged in wavy layers and bands
Non-foliated metamorphic rocks like quartzite and marble, composed mainly of minerals that form with blocky crystal shapes
Mechanical Weathering process that breaks down rocks and minerals into smaller pieces but does not involve any change in their composition
Chemical Weathering process by which rocks and minerals undergo changes in their composition due to chemical reactions with agents such as acids, water, oxygen, and carbon dioxide
Erosion removal and transport of weathered materials from one location to another by agents such as water, wind, glaciers, and gravity
