CHAPTER 4
1. Be able to draw
the rock cycle
2. Define the
following terms to whoever you want. If they get bored, find someone else, but
never give up!!!!!!!!
magma; lava;
intrusive; extrusive; pluton; dike; geothermal gradient; differentiation;
continuous branch; discontinuous branch; bowen’s reaction series; mafic;
intermediate; felsic; partial melting; viscosity; phaneritic; porphyritic,
aphanitic, vescicular; glassy; pyroclastic; sill; Dyke, laccolith; batholith;
In what kind of rocks would you expect them?
3. sketch Bowen’s
reaction series showing all the minerals, and label it, and you’ll see your
spouse is going to admire you. Understand how the chemical composition of the
remaining magma changes during crystallization!
4. It is time to
explain what is magmatic differentiation, how different rocks could form from
one magma? Or how can different magmas form in different plate tectonic
environments?????
5.Texture of
igneous rocks
6. Classification
of igneous rocks?
7. Describe rocks
in the mafic, intermediate, felsic group. For this, I think it is better to find
someone who is also taking this class for credit.
8.What is
viscosity, and explain the effects of temperature and SiO2 content.
9. Understand the
different igneous bodies, and be able to sketch them.
