Why are dark colored igneous rocks heavier than light colored ones?
As a first approximation, the colour of igneous rocks gives an estimate of the concentration of iron in it. Very dark igneous rocks commonly a large fraction of minerals with iron as a major constituent. As those minerals are denser than most other silicate minerals occuring in igneous rocks, dark colored igenous rocks are usually denser than the ligher ones.
Does andesite thus have more or less dark minerals?
That depends on what you are comparing it to. It has more dark minerals than rhyolite but fewer than basalt.
The mantle is denser than the crust because it contains more what?
The mantle is denser than the crust because it contains more iron and magnesium-rich minerals. These minerals have a higher density compared to the minerals found in the crust, such as silica and aluminum.
Do minerals float on water?
Most minerals are denser than water, so they will sink rather than float. However, some minerals like pumice have a low enough density to float on water.
Is air denser than bromine?
No, air is not denser than bromine. Bromine is a dense, dark red liquid at room temperature, while air is a mixture of gases, with a lower overall density.
Why Seawater is typically denser than freshwater?
Seawater is denser than freshwater because it contains dissolved salts and minerals, such as sodium and chloride, which add weight to the water molecules. These dissolved substances increase the overall mass of seawater and make it denser than freshwater.
Does malachite float on water?
No, like the vast majority of minerals, malachite is considerably denser than water.
Is water heavier than everything?
No. For example, a kilogram of water is lighter than a ton of marzipan. If you mean is water denser than everything than the answer is still no. Many substances including nearly all metals and minerals are denser than water.
Who is denser white dwarf or a planet?
A white dwarf is denser than a planet. White dwarfs are stellar remnants that have collapsed under gravity, packing a large amount of mass into a small volume. Planets, on the other hand, have much lower densities compared to white dwarfs due to their composition and structure.
Why seawater lighter than river water?
sea water is less denser than river water.
Is red denser then blue?
Photographically, both reflect about 50% of the white light falling on them, depending, of course, on their hue. A really dark blue would reflect far less than a light red, same with blue.
How dense is the white dwarf to your sun?
A white dwarf is much denser than the Sun. White dwarfs have a typical density around 1 million times greater than the density of the Sun, resulting in a mass similar to the Sun's but packed into a much smaller volume.
