When basalt comes into contact with water, chemical weathering occurs due to the presence of water and ions like H+ and OH- that can react with the minerals in basalt. Over time, this weathering can lead to the breakdown of basaltic minerals and the formation of secondary minerals like clays and oxides.
Basalt is a type of igneous rock that is formed from the cooling and solidification of lava. It is considered a chemical sedimentary rock, as its minerals crystallize directly from magma and do not involve the accumulation of organic or clastic material.
After boiling, the film on water evaporates and disappears.
Yes. All igneous rocks contain silicon. By weight basalt is 45-53% silica, which works out to 21-24% silicon.
Alkali basalts are a type of basaltic rock that is enriched in alkali metals (such as potassium and sodium) compared to other basaltic rocks. They typically have a higher content of minerals like feldspar and pyroxene, and are associated with volcanic activity in rift zones and oceanic hotspots.
When silver is added to water, it does not react with the water. Silver is a noble metal and is relatively unreactive with water at room temperature.
I am not sure what you mean by "smaller" BUT - Most piles of basalt on the planet (eg hawaii) are in water - Indeed the whole oceanic seafloor is basalt, so there is more basalt in water than ALL the basalt to be found on land.
No, basalt is more dense than water. The density of basalt ranges from 2.8 to 3.0 grams per cubic centimeter, while the density of water is 1 gram per cubic centimeter.
nothing it has no calcite
No, basalt is a dense volcanic rock formed from solidified lava, so it will sink in water.
yes. some types of basalt is found of volcanoes.
Basalt cools off quickly because it is formed under water.
No, basalt does not float in water because its density is higher than the density of water. Basalt is a dense volcanic rock formed from the solidification of lava, which causes it to sink when placed in water.
Basalt.
Crystals in basalt that formed underwater are smaller because they cool faster in the water, resulting in less time for the crystals to grow. On the other hand, crystals in basalt that formed on the ground have more time to grow as they cool more slowly, leading to larger crystal sizes.
Pillow basalt forms underwater. Water absorbs heat from lava much more quickly than air does.
No. Salt is extracted from deposits left by salt water bodies. The similarity in names between salt and basalt is purely coincidence.
Pillow basalt is formed from solidifying lava which erupts under the surface of a body of water. Because of this, it cools much faster, allowing less time for crystal growth.
