project 1

please provide short answers for the following:

· Explain how geology incorporates the other sciences, and how it is different from the other sciences

· Discuss why we study the Earth and what type of work geologists do

· Define some of the properties of a mineral and explain the differences between minerals and rocks

· Describe the nature of atoms and their constituents, particularly the behavior of electrons and the formation of ions

· Apply your understanding of atoms to explain bonding within minerals

· Describe mineral lattices and explain how they influence mineral properties

· Categorize minerals into groups based on their compositions

· Describe a silica tetrahedron and the ways in which tetrahedra combine to make silicate minerals

· Differentiate between ferromagnesian and other silicate minerals

· Explain some of the mechanisms of mineral formation

· Describe some of the important properties for identifying minerals





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
