Lava may form a mountain called a?
volcanoe
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.
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 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!
Describe pillow lava?
Because it solidifies outside the surface of the earth, it is an extrusive igneous rock.
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.
A caldera is a depression in a volcanic mountain A caldera may form when?
The mountain collapses into an emptied magma chamber
When lava gets in oceans can people die swimming in it?
It is possible. The lava would heat the water a lot. The people may die from that.
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.
The hole in the top of a volcano?
The top of a volcano may be a peak, lava dome, vent, crater, or caldera (empty magma chamber), depending on the state of the volcano. The top of any mountain can be called its summit.
