Lava solidifying into basalt typically occurs at volcanic regions, particularly at mid-ocean ridges, where tectonic plates are diverging, and in hotspot areas like Hawaii. It can also form during volcanic eruptions on land, such as those from shield volcanoes, where low-viscosity basaltic lava flows easily. The resulting rock is characterized by its fine-grained texture due to rapid cooling.
What else can I help you with?
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.
Did basalt form slow or quick?
Basalt typically forms relatively quickly, as it is created from lava cooling and solidifying on the Earth's surface. The exact amount of time can vary, but it generally happens within days to weeks, depending on factors like temperature and thickness of the lava flow.
What type of rock forms when lava solidifies?
Igneous rocks form when lava solidifies. These rocks are formed from the cooling and solidification of molten materials that originate from deep within the Earth's mantle or crust. Examples include basalt, andesite, and rhyolite.
If a lava flow at Earth's surface had a basaltic composition what rock type would the flow likely turn into upon solidification?
It would form into the rock basalt, an extrusive, mafic, igneous rock.
Which type of lava would most likely form lava tube caves?
Pahoehoe lava, which has a smooth, rope-like texture and forms by flowing rapidly and cooling quickly, is more likely to form lava tube caves due to its ability to retain heat and flow for long distances before solidifying. Aa lava, with its jagged and blocky texture, tends to move more sluggishly and is less likely to create extensive tube structures.
Where would you expect to find lava solidifying into basalt?
You would expect to find lava solidifying into basalt at the surface of a volcano or lava flow. Basalt is a common volcanic rock that forms when lava cools and solidifies quickly, usually in areas with high volcanic activity.
How would you connect the words lava and basalt?
Most lava forms a rock called basalt when it cools.

Is basalt formed by lava?
Yes, basalt is formed by the cooling and solidification of lava erupting from volcanoes. It is a common type of extrusive igneous rock and has a fine-grained texture due to its rapid cooling on the Earth's surface.
What was the basalt and igneous rock formed by?
Basalt and igneous rocks were formed by what we would call magma/lava
What type of rocks form from lava after a volcanic eruption?
Igneous rocks are formed from the cooling and solidifying of magma. The resulting rock can be instrusive (magma cooling within the crust) and extrusive (lava cooling on the surface). The most common kind of rocks are Granite (intrusive) and Basalt (extrusive).
What type of rock forms when lava solidifies?
Igneous rocks form when lava solidifies. These rocks are formed from the cooling and solidification of molten materials that originate from deep within the Earth's mantle or crust. Examples include basalt, andesite, and rhyolite.
How are lava tube cave foromed?
They form in relatively low-viscosity "basic" (low-silica, basalt) lava flows by the surface solidifying over still-flowing molten rock. If the molten lava drains away it leaves a cavity within the mass of the flow. Main lava caves of the word are on Iceland and Hawaii. Fingal's Cave, on the Isle of Staffa, is in columnar flood-basalt but is a marine-erosion feature.
If a lava flow at Earth's surface had a basaltic composition what rock type would the flow likely turn into upon solidification?
It would form into the rock basalt, an extrusive, mafic, igneous rock.
What kind of lava comes from Mt Fuji?
basalt lava
What is the lava of surtsey?
the magma and lava in Surtsey are of alkali olivine basalt, which is the type of basalt found in Vestmannaeyjar (Westman Islands)
