What kinds of studies investigate the lithosphere? - ANSWER: Geology and
Geomorphology
Geology - ANSWER: Study of Earth's history, composition, internal structure, surface
features and processes acting on them.
Geomorphology - ANSWER: Study of landforms, relating to the external processes of
Earth.
Endogenic System - ANSWER: Processes which drive the earth's interior, driven by
heat.
Exogenic System - ANSWER: processes operating at Earth's surface, driven by solar
energy and the movement of air, water, and ice
What kinds of phases exist in the history of Earth? smallest to largest - ANSWER:
Epochs, Periods, Eras, Eons

Minerals - ANSWER: building blocks of rocks
Rocks - ANSWER: Assemblage of minerals bound together or a mass composed of a
single mineral.
The 3 rock types - ANSWER: igneous, sedimentary, metamorphic
Igneous - ANSWER: Formed from molten material
Sedimentary - ANSWER: Formed from sediment deposited by water or air.
Metamorphic - ANSWER: Rocks changed by intense heat or extreme pressure
Theory of Plate Tectonics - ANSWER: Alfred Wegener suggested that continents were
at one time connected, using evidence from all over the world in 1912.
Subduction - ANSWER: Key state for plates. Collides slowly & denser floor grinds
beneath lighter continental crust.
