What else can I help you with?
What forms as result of lava that has cooled at the top of a volcano?
When lava cools at the top of a volcano, it forms igneous rocks such as basalt or andesite. These rocks can sometimes create formations like lava domes or hardened lava flows.
What is the fastest lava can travel?
IT is travelling at its fastest when it gushes out of a vent to form a lava fountain.
What is an area covered by lava as it pours from a vent?
An area covered by lava as it pours from a vent is a lava flow.
What is the hardened layer of lava called?
The hardened layer of lava is called "igneous rock".
Is hardened lava a mineral?
Hardened lava is considered igneous rock, composed of minerals.
When magma leaves the vent of a volcanowhat is it called?
Lava if it is liquid, which then freezes. Ejecta if it is in the form of bombs or ash.
Where do lava tube caves form?
Lava tube caves form when low viscosity lava flows beneath the hardened surface of lava flow while the volcano is active. Then when the volcano is dormant or extinct, it leaves cave like channels.
What are the cycles of lava?
The cycles are molten rock, lava, and then hardened lava like obsidian.
What is a secondary vent?
a secondary vent is a vent or tube that connects to the secondary cone for the lava to flow.
Is mount Pelee a pipe a vent a cone or a crater?
Mount Pelee is a stratovolcano, which is a type of cone-shaped volcano built from many layers of hardened lava, tephra, pumice, and volcanic ash. It is not a pipe, vent, or crater, although it does have a central vent that allows magma to reach the surface during eruptions.
What forms from hardened lava?
igneous rocks
Compared to the particles in a hardened lava sample the particles in a liquid lava sample?
The particles in a hardened lava sample will be solidified and compacted, while the particles in a liquid lava sample will be molten and in a flowing state. The hardened lava particles will have a crystalline structure, whereas the liquid lava particles will lack a fixed arrangement due to their high temperature.
