What else can I help you with?
Would it be possible for volcanoes and lava flows to form on a planet with no liquid water?
Yes, volcanoes and lava flows can form on a planet with no liquid water. Volcanoes are typically formed by tectonic activity, where molten rock (magma) from the planet's mantle is able to reach the surface. The presence of liquid water is not a requirement for this process to occur, as volcanic activity can still take place on planets with dry surfaces or alternative substances that facilitate magma eruptions.
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.
Are composite volcanoes predominantly erupting with lava flows?
No. Composite volcanoes erupt mostly ash and pumice.
What does lava have to do with volcanoes?
Lava is molten rock that flows out of a volcano.
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.
Why are there different shaped volcanoes?
Different shaped volcanoes occur because of the way the magma flows. Three types of volcanoes are shield, composite, and caldera.
Venus surface features?
Venus has a rocky, mountainous terrain with several notable features such as vast plains, massive volcanoes, and deep canyons. The planet's surface is littered with thousands of volcanoes, including the massive Maxwell Montes, as well as a network of deep rift valleys known as tesserae. Venus also has extensive lava flows and highland regions, making it one of the most geologically diverse planets in our solar system.
What are tyes of volcanoes?
There are three main types of volcanoes: shield volcanoes, cinder cone volcanoes, and stratovolcanoes. Shield volcanoes have gentle slopes and are formed by thin lava flows. Cinder cone volcanoes are made up of pyroclastic material, such as ash and rock fragments. Stratovolcanoes are large, steep-sided volcanoes that erupt a mixture of lava flows and explosive eruptions.
Which type of magma causes quiet volcanoes?
Mafic magma (low in silica content) typically causes quiet eruptions because it is less viscous and flows more easily, leading to gentle lava flows. These eruptions are characterized by low explosivity and can result in shield volcanoes or lava plateaus.
What are the broad slightly dome-shaped volcanoes called?
a broad-domed volcano is formed by lava flows. the amount of times the volcano has erupted effects how broad the dome would be, because when the lava flows it wears away the dome of the volcano.
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.
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.
