Lava may form a mountain called a?

Very fluid balsaltic lava may erupt out of fissures in the surface When the lava hardens it may form a feature called a?
Lava plateau
Does lava have gas?
Yes. Gases may be trapped in lava. These may form bubbles on the surfaces of a flow, giving it a vesicular texture when it cools.
Which features may occur when volcano lava cools at the surface?
Lava that cools at the surface can form features such as lava flows, which are large sheets of solidified lava. It can also create lava tubes, which are tunnels formed when the outer layer of the lava flow cools and hardens while the inner lava remains molten and continues to flow. Additionally, lava may form spatter cones or lava fountains when ejected into the air and solidifies before hitting the ground.
What do volancos look like?
Depending on where you are looking from, it changes. From the bottom of it, it would look like a mountain, may be grassy/rock/metamorphic rock. From a birds eye view it would look very different. Depending if it is dormant, living or extinct it would still look like a mountain but with a creater in the middle. This may be steaming, have lava in it or just be rock.
What features may occur when volcano lava cools at the surface?
When volcano lava cools at the surface, it may form different features such as lava rock formations like basalt columns, lava tubes, and aa or pahoehoe lava flows. These features depend on the cooling rate and composition of the lava.
When a volcano erupts lava may flow onto the surface. What type of rock does the lava cooling form?
When lava cools on the surface, it forms igneous rock called basalt.
What rocks come from lava flow?
Lava flows cool to form extrusive igneous rock. Most lava flows consist of basaltic lava, cooling to form a dark rock called basalt. Some, however, may consist of andesite or, rarely, rhyolite and similar lavas.
How do volcanos affect the Earth's surface?
Volcanoes can change the surface of the earth in several ways. The lava that is ejected for the volcano may dry and form a new layer of sediment on the ground. The chambers of magma underground can become too pressurized and make a whole new volcanic mountain. Hope that answers your question!
What is on top of a volcanic mountain?
A volcanic mountain can have a crater at its summit, which may contain a volcanic vent, lava dome, or caldera. The top of a volcanic mountain can also be covered in ash, rock debris, and volcanic gases.
What are lava roses?
A lava rose is a rare drip formation found on floors, with a rose-like appearance. It is a form of drip stalagmite, but instead of driblets, sheets of molten lava fall. Roses may also form, instead, from upwelled lava boiling up out of a partially solidified floor. Boiling of cooling (segregated) lava is probably what propels the upwelling.
How can a cone shaped mountain form?
A cone shaped mountain may be kind of volcano called a stratovolcano, which is built from ash deposits and very viscous lava flows. Some stratovolcanoes have very well formed cones, including Mount Fuji in Japan, and Mount St Helens prior to its cataclysmic eruption in 1980.
