Assignment:
For project 2, please provide short answers for the following:
Briefly describe the processes that lead to the formation of igneous, sedimentary, and metamorphic rocks
Explain partial melting and the geological processes that lead to melting
Describe, in general terms, the range of chemical compositions of magmas
Discuss the processes that take place during the cooling and crystallization of magma, and the typical order of crystallization according to the Bowen reaction series
Explain how magma composition can be changed by fractional crystallization and partial melting of the surrounding rocks
Apply the criteria for igneous rock classification based on mineral proportions
Describe the origins of phaneritic, porphyritic, and pegmatitic textures
Explain the relationships between plate tectonics, the formation of magma, and volcanism
Describe the range of magma compositions formed in differing tectonic environments, and discuss the relationship between magma composition (and gas content) and eruption style
Briefly identify the types of hazards posed to people and to infrastructure by the different types of volcanic eruptions
