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.
What else can I help you with?
Is basalt chemical clastic or organic?
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.
What happens to the film on water after boiling?
After boiling, the film on water evaporates and disappears.
Is basalt have silicon in it?
Yes. All igneous rocks contain silicon. By weight basalt is 45-53% silica, which works out to 21-24% silicon.
What is an alkali basalt?
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.
What happens when silver is added with water?
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.
Why are the basalt that were born in water are smaller than the ones on ground?
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.
Is basalt less dense than water?
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.
What happens to basalt when acid is added?
nothing it has no calcite
Does basalt can float on water?
No, basalt is a dense volcanic rock formed from solidified lava, so it will sink in water.
Is basalt found under water and by volcanoes?
yes. some types of basalt is found of volcanoes.
Why does basalt rocks cool slowly?
Basalt cools off quickly because it is formed under water.
Does basalt float in 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.
What type of rock will you find at a bottom of bodies of water?
Basalt.
Why are crystals in basalt that formed under water smaller than those in basalt that formed on ground?
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.
Why are the crystals smaller in basalt pillows?
Pillow basalt forms underwater. Water absorbs heat from lava much more quickly than air does.
Is basalt used to make salt?
No. Salt is extracted from deposits left by salt water bodies. The similarity in names between salt and basalt is purely coincidence.
Why are the crystals in pillow basalt smaller than the crystals in basalt that forms in the ground?
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.
