What are advantages and disadvantages of volcanoes?
Volcanoes can create more land but can kill plants and animals while flowing lava.
What is the difference between acid lava cones and ash and cinder cones?
Acid lava cones are smaller and much steeper than ash/cinder cones. Acid lava cones are almost convex in shape and are formed due to thick lava that does not flow freely and cools before reaching very far. This gives in the conical 'dumpy' shape. While ash and cinder cones are more symmetrical and concave in shape. They are formed due to volcanic lava or volcanic bombs (of solidified lava) that was shot up in the air, cool and hardened and broke up into tiny pieces (of ash or cinders) before coming back down to the earth's surface.
Are volcanoes constructive?
Yes. What happens is when the lava cools down, it turns into rock.
What lava would be very painful to walk across with bare feet?
All
This lava would be very painful to walk across with bare feet?
Aa
What is the tunnel where the lava travels to the top called?
lava tube
How far on average does lava travel?
There's a range for lava flow that stretches from a few inches to a number of miles. It depends mostly on a lava's viscosity. Highly vuc\\iscous lava volcanoes, such as Mt. St. Helens, tend to erupt violently, but lava flows are slow and quick to solidify. Underwater eruptions may have lava that solidifies on the outside almost instantly. Extremely low viscosity lava flows, like those in Hawaii, may run for days and cover miles before solidifying.
What is the term for lava flow that travels downhill at over 100mph?
Pyroclastic flow
Is there a difference between lava and lava flow?
Yes, there is a difference between lava and lava flow. Lava is the molten rock beneath the Earth's surface, while lava flow refers to the movement of lava as it travels down a volcano or hillside. Lava flow is the result of the eruption of molten rock, which can vary in speed and direction.
What is the tube that lava travels through?
It travels through a "Pipe" and explodes out the "Vent", or possibly the "Side Vent", and another world for the hole at the top is the Crater.
How lava travels?
It travels as a liquid, in response to gravity and obstructions, until friction or solidification overcome the force of gravity.
What is the phenomenon that occurs when molten lava flows through a natural tunnel-like structure underground, known as a lava tube, and what travels through it?
The phenomenon is called lava tube formation, where molten lava flows through a natural tunnel-like structure underground. Lava travels through these tubes, allowing it to move further away from the volcanic vent.
What is the tunnel that lava travels to reach the top of the volcano called?
The tunnel through which lava travels to reach the surface of a volcano is called a volcanic conduit. It is a passage that connects the magma chamber below the volcano to the vent at the surface. The lava moves through this conduit under pressure before erupting onto the surface.
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 the difference between a pahoehoe and AA?
Pahoehoe is so much more smoother and duller than AA, because it travels down a gentler slope. You can drive over Pahoehoe. AA, travels down a much steeper slope, and stumbles over itself, and when it hardens, it becomes VERY SHARP AND RAGGED. You wouldn't even be able to walk on AA lava without seriously messing up your feet.
How long can magma flow until cooling?
Magma flows for a long period of time but named lava when out of the ground. It depends how fast the lava is travels, but you can usually run from it:)
What is lava that travels 100 mph down a hill called?
The closest match to this is a pyroclastic flow, but it isn't exactly lava: it is a cloud of hot ash, rock, and gas.
