Sediments The particles of matter
Deposits To leave an amount of something overtime
Organic of, relating to, or derived from living matter
Fossils Organic. The remains from an organic organism preserved in rock.
Fossils in Sedimentary Rocks Most commonly found. The rocks form at temperatures and pressures that do not destroy fossil remnants.
Fossils in Igneous Rocks Not as common because they are formed from hot lava or magma and they would just burn up or destroy.
Law of Superstition Oldest rocks are on the bottom
Theory of Plate Tectonics The earths crust and upper mantle are broken into sections called plates. They float on the mantle and move slowly

Alfred Wagner Proposed the continental drift in 1912
Uniformitarianism Assumption that all scientific laws have been the same throughout time
Sea Floor Spreading The Spreading of the sea floor from molten rock
What Causes Plate Tectonic Movement Convection of heat from the core of the earth to the plate.
Types of Heat Conduction, Convection, Radiation
Conduction Transfer of heat of something that is touching
Convection The movement of heat from liquids to gases
Radiation Movement of heat without matter
Structure of the Earth The earth is made up of 3 main layers: -Core -Mantle -Crust
Lithosphere Made up of the crust and upper part of the mantle. Tectonic Plates are made up of this.
Plate Boundaries 3 Types: Divergent Convergent Transform
Divergent Boundaries Pulling apart Ex. Mid Atlantic Ridge
Convergent Boundary Going together Ex. Himalayas
Transform Boundary Where Plates Slide past each other Ex. San Andreas Fault
Subduction When two plates meet one goes under creating a volcano
Ring of Fire A circle of plate boundaries there is volcanoes (Circles the Pacific Plates)
