Which rock has more silica in it likely to be lighter or darker than a rock with less silica in it?

It will be lighter. Because the silica makes the rocks explode from the valcanos. The only rock that has height silica content and is dark is Quartz.

Does gabbro have a higher silica content than granite?
Gabbro has less silica than granite.
Does soil color change as you get deeper?
Yes. As you get deeper, soil starts getting less water, so it gets lighter in color, whereas the surface is always darker due to watering :)
What type of plate boundary would have less silica content?
divergent boundary
What is a light colored rock that has high silica?
Felsic igneous rocks with alkali feldspars, quartz, and mica. Examples would include rhyolite, pumice, granite, and obsidian.
Why does plates sometime sink into the mantle?
Because a "lighter" (less dense) plate floats above it. Note; continental plates are less dense than seabed.
Is a rock with more silica in it likely to be lighter or draker than a rock with less silica in it?
more silca means lighter color less silca means darker color.
Has anyone been able to explain why lighter hair has less oil than darker hair?
i think that you are just more likely to see the oil in darker hair than in lighter hair because the oil stands out more in dark hair.
Why is magma that contains little silica less likely erupt explosively?
Magma with less silica is thinner and runnier.Therfore, gases can move out of the magma easily.

Why is your hair color they color it is?
Hair color is caused by the pigments in your body. The less pigment you have the lighter your hair. Less pigment also means you will have lighter skin that is why people who have darker skin have darker natural hair usually and why people with lighter skin have lighter hair. the amount of pigment you have depends on who your parents are. If your parents have more pigment you will probably have more pigment and if your parents have less pigment you will probably have less. Hope this helps! :)

What is the role of the melanin in the skin?
It is what gives your skin color. If you have more melanin in your skin, your skin will be darker, if you have less, your skin will be lighter.
Light colored igneous rocks are less what than dark igneous rocks?
basaltic rocks are darker because they are more dence granitic rocks are less dence so they are lighter
Is something wrong with you if your pee turnes darker?
When your pee is darker it means it's more concentrated so you need to drink more water, the more water you drink the lighter your pee will be and the less smelly too.
In general how does the density of a light colored igneous rock differ from that of a dark colored igneous rock?
Light-coloured igneous rocks, such as granite, have a higher silica content and lower iron and magnesium than darker ones, such as basalt. Since iron and magnesium are very dense minerals, this makes darker igneous rocks more dense than lighter ones.
Why is magma with less silica less likely to cause explosive eruptions?
The silicate compounds are more viscous and hold gases and water under pressure, and the gases and steam expand violently once the lava reaches the surface. Less silica means that some of these gases will bubble out before reaching critical pressure.
