What does lava have to do with volcanoes?
Lava is molten rock that flows out of a volcano.
What is the name of mountain from which the lava flows out?
A volcano is a mountain from which lava flows out during an eruption.
Why is it that pahoehoe and AA lava are more frequent in shield volcanoes than in composite volcanoes?
Shield volcanoes have low viscosity basaltic lava, which typically creates pahoehoe and AA lava flows due to their ability to flow easily. Composite volcanoes have higher viscosity lava, such as andesitic or dacitic, which tend to form thicker and blockier lava flows rather than pahoehoe and AA flows.
What planet is covered with lava flows and has several volcanoes?
Venus.
Molten material that flows from volcanoes?
Molten material that flows from volcanoes is called lava. This hot, liquid rock can reach temperatures of over 1,300 degrees Fahrenheit. As it cools and solidifies, it forms igneous rocks like basalt or andesite.
Which volcanoes are Massive gently sloping volcanoes built of successive basaltic lava flows?
Massive gently sloping volcanoes built of successive basaltic lava flows are called shield volcanoes. Examples of shield volcanoes include Mauna Loa in Hawaii and Mount Etna in Italy. These volcanoes are characterized by their broad, low-profile shape and the relatively peaceful eruptions of fluid lava.
Are composite volcanoes predominantly erupting with lava flows?
No. Composite volcanoes erupt mostly ash and pumice.
Why does a cinder cone volcanoes have such steep sides?
when lava flows down it the lava that stayed on it gets hard
What are constructive volcanoes?
Constructive volcanoes, also known as shield volcanoes, are characterized by their broad, gently sloping sides and low viscosity lava flows. These volcanoes are typically formed from multiple eruptions of basaltic lava, which spreads out in thin layers to create a gradual and shield-like shape. Constructive volcanoes are associated with effusive eruptions, where lava flows steadily and continuously.
Why is venus hot than mercury?
Because Venus is global warming x1000 the gases caused by the volcanoes and lava flows trap Heat in
What is magma called that comes out of volcanoes?
Magma that comes out of volcanoes is called lava. Lava is molten rock that flows out of a volcano during an eruption.
What are all kinds of volcanoes?
The main types of volcanoes are stratovolcanoes (composite volcanoes), shield volcanoes, cinder cone volcanoes, and lava dome volcanoes. Stratovolcanoes have steep slopes due to the alternating layers of lava flows, ash, and other volcanic debris. Shield volcanoes have gentle slopes due to the low-viscosity lava flows. Cinder cone volcanoes are small and steep-sided, formed from explosive eruptions. Lava dome volcanoes are formed from slow, viscous lava flows piling up near the vent.
