Compare the ways in which ironmagnesium minerals and feldspars crystallize from magma?

In Bowen's reaction series, feldspar minerals go through a continuous change of composition, while iron-magnesium groups have an abrupt change of mineral types.
When magma cools, the feldspars that form are calcium-rich. As cooling continues, the feldspars react with magma and the feldspar composition changes. The result is a zoned crystal with sodium-rich outer layers and calcium-rich core.
For iron-magnesium minerals, when magma starts cooling, a mineral begins to crystallize. However, when the magma temperature drops, a whole new mineral begins to form. The previously formed minerals reacts with the magma and is converted into the new mineral.

How can you compare the density of two different minerals?
If you use the formula: M/V it will compare the different minerals
How do you compare and contrast rocks and minerals?
You can put a Venn Diagram and on top of 1 side you can put rock and on top of another side you put minerals and the middle part is how both are alike. Then you write how minerals are different then rocks on the minerals side and write how rocks are different on the rock side.
Compare and contrast granite and diorite?
Contrast: Granite consists mainly of quartz, feldspar, and ferromagnesian ("dark") minerals Diorite may be incorrectly called "granite". Diorite contains virtually no quartz, no muscovite, and no K-feldspar. It also contains a higher percentage of dark silicate minerals. Diorite has a salt and pepper appearance. Compare: Both granite and diorite are phaneritic (course-grained) rocks. Diorite is primarily sodium- rich plagioclase feldspar and amphibole, with lesser amounts of biotite. On other minor constituents of granite include muscovite and some dark silicates, particularly biotite and amphibole.
What kind of machine could you compare a glacier to?
What kind of machine could you compare a glacier to ? You can compare it to a freezer.Because glacier is ice and a freezer makes ice.
Why do scientists classify and compare climates?
So that they can compare regions of the earth more easily.

What are some other ways in which scientists might compare minerals?
some other way the scientist can compare minerals is crashing each other or take some elements and them revise it.
Compare the chemicals or minerals in our tap water and NEWater ..?

What is special about bare minerals?
What is special is that bare minerals don't give you that "cakey" look, it feels like you're not wearing anything either. They usually compare bare minerals to everyday minerals. Everyday minerals are said to be cheaper and come in different shades.
Compare the chemicals or minerals found in your tap water and the new water?
because it is lame

What is the Chemical formula for plagioclase?
Feldspar makes up over half of the earth's crust. It consists of continuous, negatively charged, three-dimensional framework that is made up of corner-sharing tetrahedrons and positively charged cations.
Why was Freidrich Mohs work important?
Mohs created the Mineral Hardness scale in 1822. It is a comparison table showing 10 common minerals and their relative hardness values. Scientists can use it to compare to other unknown minerals and for classification of minerals. In science you always want to be able to compare something to something else. So instead of saying something is soft or hard, the Mohs Scale gives a relative value to the description.
Does metamorphic rock have a lot of pores or openings?
Rocks that have undergone metamorphism, have been changed by heat and pressure, such that their mineral assemblage is changed. The micas are among the last of the minerals to crystallize, and are often used as samples to define the date of that metamorphism. In general the metamorphosed rock will be more dense than the original. Compare marble and limestone. Marbles are about the least metamorphosed rock. Where the rock has been completely melted, and no trace of their original structure remains, they are called plutonic.
How do rocks that astronauts gathered on the moon compare with rocks and minerals on the earth?
They appear to be igneous in nature with earth common minerals. Because the earth is geologically active and has flowing water, we see all rock types on the surface.
Why are some rocks and minerals more special than other rocks?
because it has some precious value s compare to the oters metals
