What kind of igneous rock makes up most continental crust rocks?
granite or rhyolite
Describe the different minerals that determine the color of granite?
Magma that is high in silica usually forms light-colored rock, such as granite. Grantis, however, comes in many shades and colors, from nearly black to light gray, red, and pink. The mineral composition of granite determines its color. ^______^
How do geologists estimate the age of mountains?
First: geologists look at the general shape of the mountain: Sharper peaked mountains are generally younger than rounded ones because erosion has had less time to wear them down (ie the Rockies are younger than the Appalachians). Second: geologists look at what type of rock is exposed. Not only does this tell us something about when the formation began, it also gives us something to base our erosion estimation off of. Sandstone erodes faster than granite, so you could have a rounded mountain peak made of sandstone that was the same age as a sharp granite peak. Third: geologists will consult with paleontologists and archaeologists to try to determine the age of the mountain based off of remains that may be present on the mountain. (If, for instance, we find fossil sea-shells, we know that the mountain formation has to fall within certain ranges).
What type of rock is the El Capitan Rock?
Granite
What is the characteristics of granite?
Granite is coarse grained, has a uniformly dispersed crystalline structure, has a specific gravity of 2.6-2.7, is composed of varying amounts of various feldspars, quartz, micas, and other minerals, even small amounts of uranium. Granite is hard, tough, and resistant to fracture because of the interlocking structure of the minerals within. Granite's colors are varied; pinks, reds, and gray are most common. Its porosity is negligible, between 0.3 to 4%. It's weather resistant, heat resistant and even chemical resistant.
Who studied rock?
Geologists study the rocks that compose the earth or other terrestrial planets. Mineralogists classify and name types of lava. Stone cutters study granite , which is an igneous rock.
How do geologists determine the mineral compostion of granite?
They basically cut or slice the granite apart exposing the "real" minerals inside.

How geologists determine the mineral composition of granite?
The minerals are for the most part observable in a coarse grained igneous rock such as granite. If necessary, however, thin slices of rocks are made to be viewable under a microscope that could help identify trace minerals.
Describe one use for the igneous rocks granite basalt and pumice?
granite: sismecology basalt: hyperbole pumice: your big fat butt
How do you describe kneeling statute of hatshepsut?
She was knelling alright. The statute was make out of granite.
Which term or terms could be used to describe this sample of granite?
heterogeneous mixture
Is gneiss clastic organic or chemical?
None of the above. These terms describe sedimentary rocks. Granite is igneous.

Is granite foliate?
No. Foliation is a texture most often used to describe the banded, platy, or layered appearance of certain metamorphic rocks.
