An igneous rock that contains quartz and potassium feldspar would have a mineralogic content placing it in the range of
granitic or fesic rocks
What is a coarse-grained rock composed of intermediate plagioclase feldsapr and pyroxene?
Texture is fine-grained
Chemical Composition: Granitic (Felsic)
Dominant Minerals: Quarts, Potassium Feldspar, Sodium-rich plagioclase feldspar
Chemical Composition: Andesitic (Intermediate)
Dominant Minerals: Amphibole Sodium and calcium rich plagioclase feldspar
Chemical Composition: Basaltic (Mafic)
Dominant Minerals: Pyroxene, Calcium-rich plagioclase feldspar
Chemical Composition: Ultramafic
Dominant Minerals: Olivine Pyroxene
Igneous Rock Textures
and intrusive and extrusive crystal formation characteristics show that igneous rocks can have the smae mineral composition, but be different rocks.
Can you determine what types of igneous rock share the same mineral composition butr are different in texture and therefore different rocks?
Rhyolite, Diorite, Gabbro, Peridotite
In the list shown below, label each item for the location where it primarily occurs:
see image to the right
In the image below, lable the arrows for the correct processes of the rock cycle
Weathering, transport, deposition,
Metamorphism (heat, intense pressure)
Can you determine by what process the following rocks formed? Sort the images into their correct vins based on whether they were formed by igneous, sedimentary, or metamorphic processes
Can you determine what type of igneous rock would result from various cooling histories and locations?
Can you determine what types of igneous rock share the same mineral compostion, but are different in texture, and are therefore different rocks?
see image (Rhyolite, Diorite, Gabbro, Peridtite)
When do all locations on Earth experience equal lengths of day and night?
September and March Equinox
to be classified as rain, water droplets that fall from a could must be of what minimum diameter?
In which direction would winds move at the poles if Earth rotated in the opposite direction?
Wind from the north pole would move to the southeast, and the wind from the south pole would move to the northeast.
Which of the following celestial bodies has a geocentric orbit?
Which of the following scientists first constructed the heliocentric model for the solar system?
Which of the following best explains the formation of the four inner (terrestrial) planets?
