1.because it is called a extrusive rock
2. it doesnt have big crystals
Basalt cools off quickly because it is formed under water.
Since basalt is extrusive it cools quickly and forms small crystals.
Basalt cools fast because it is at the surface, where air carries heat away rather quickly.
Lava will cool quickly compared to underground magma.
When lava cools down quickly at the surface of the Earth, it forms an igneous rock called basalt. Basalt is dark in color, fine-grained, and contains minerals such as olivine and pyroxene.
Igneous rock, specifically basalt, is formed when lava cools quickly. Basalt is characterized by its fine-grained texture due to rapid cooling at the Earth's surface.
it comes from magma inside the volcanoes then it cools and it turns in to basalt
A gas filled rock that cools quickly is likely a vesicular basalt. This type of rock forms from lava that is erupted from a volcano and cools rapidly, trapping gas bubbles inside. The rapid cooling prevents the bubbles from escaping, creating a porous texture.
Pillow basalt forms when basaltic lava erupts underwater and cools rapidly, creating pillow-shaped structures. Water cools the lava quickly, causing it to solidify into distinctive pillow-like shapes as it is extruded.
i dont know thats why i am asking you do you know
Basalt is formed when low-silica lava erupts from a volcano and later cools.
Igneous rock that cools quickly may have a fine-grained texture, with small mineral crystals that are not easily visible to the naked eye. Examples include basalt and rhyolite.
