How are light colored igneous rocks different?
Igneous rocks are divided into four groups based on their composition (often determined by observing density and color).Felsic (also called Silicic) igneous rocks have a lower density, and are generally lighter in color (white, tan, pink). They have a higher silica content and a lower iron and magnesium content than the other types of rock. Granite and rhyolite are felsic igneous rocks.Intermediate igneous rocks have a density between felsic and mafic rocks. They have a high silica content and a medium iron and magnesium content. These rocks are usually gray or a similar, medium-toned color. Andesite and diorite are intermediate igneous rocks.Mafic igneous rocks are quite dense, and have a much higher iron and magnesium content than felsic or intermediate igneous rocks. Mafic rocks are usually black or blackish. Gabbro and basalt are mafic igneous rocks.Ultramafic igneous rocks are the densest type, and have the highest iron and magnesium content. Ultramafic rocks are usually (surprise!) green. Peridotite is an ultramafic igneous rock.

What are the five processes by which minerals form?
There are four ways that minerals can be formed. From molten rock, from solution, within living cells and by recrystallization.Minerals are formed in nature by a variety of processes. Among them are:Crystallization from melt (igneous rocks)Precipitation from water (chemical sedimentary rocks, hydrothermal ore deposits)Change to more stable state - (the processes of weathering, metamorphism, and diagenesis).Precipitation from vapor. (not common, but sometimes does occur around volcanic vents)
What are four things that affect the formation of rocks?
Temperature, pressure, availability of minerals...

What are the four kinds of igneous rock?
Igneous rocks are usually classified first by their color index. The color index is separated into four categories. Felsic rocks are the lightest and are composed of mostly quartz and potassium feldspar. Intermediate rocks are the second lightest and are made up of mostly plagioclase feldspar, pyroxene, amphibole, and biotite. Mafic rocks are made up of plagioclase feldspar, pyroxene, and amphibole. Ultramafic is made up of mostly olivine, with pyroxene and amphibole.

What are a map's four intermediate directions?
The four intermediate directions are northeast (NE), northwest (NW), southeast (SE), and southwest (SW). They fall between the four cardinal or standard directions of north (N), east (E), south (S), and west (W).
