What type of rock forms when lava solidifies?
Extrusive igneous rock forms from solidifying lava.
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.
Which is not a common extrusive igneous rock?
There are so many rocks that can be classified as not a common extrusive igneous rock. The most common extrusive igneous rock is basalt. Extrusive rocks are formed as a result of lava solidifying.
Which type of lava would most likely form lava tube caves?
Basaltic, low viscosity lava would form lava tube caves.
How thick is basalt?
Basalt is a rock formed from rapid cooling of lava or magma. The thickness of basalt depends on how much lava is present during cooling. Basalt can be anywhere from a few centimeters thick to many tens of meters thick.
Where would you expect to find lava solidifying into basalt?
You would expect to find lava solidifying into basalt on the flanks of a volcano, most likely a shield volcano.
Is basalt formed by lava?
yes.... it cant +++ Strictly speaking no because lava is magma erupted from a volcano whereas a pluton is frommagma solidifying below ground. That doesn't exclude volcanoes accompanying plutons.
What type of rock forms when lava solidifies?
Extrusive igneous rock forms from solidifying lava.
How would you connect the words lava and basalt?
Most lava forms a rock called basalt when it cools.
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.
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 was the basalt and igneous rock formed by?
Basalt and igneous rocks were formed by what we would call magma/lava
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.
Which is not a common extrusive igneous rock?
There are so many rocks that can be classified as not a common extrusive igneous rock. The most common extrusive igneous rock is basalt. Extrusive rocks are formed as a result of lava solidifying.
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)
Which type of lava would most likely form lava tube caves?
Basaltic, low viscosity lava would form lava tube caves.
