How many volcanoes erupted so far?
well , that is a good question ! About 1,300 has happened in the last 10,000 year. Most of these are shield volcanoes. Shield volcanoes are found under water or and form easily. three quarters ( 3/4 ) of volcanoes are shield volcanoes. SO if you subtract all of the shield volcanoes from the amount of volcanoes that have happened in the last 10,000 years it will come up to 6,000 eruptions in the last 10,000 years. This is not including under water or shield volcanoes. WELL, that's all . BYE ! (:
When magma reaches the surface what happens to the gases?
When magma reaches the surface, the gases dissolved in the magma are released due to the decrease in pressure. This release of gases can lead to explosive volcanic eruptions as the gases expand rapidly and forcefully.
What is a volcano that starts with m found on the us island Hawaii?
i believe it is on one of the islands of hawaii called maui.
Why do scientists want to know about volcanic eruptions in remote areas?
Scientists want to know about volcanic eruptions in remote areas because they can pose significant hazards to local populations, infrastructure, and the environment. Monitoring these eruptions helps in predicting potential hazards, establishing evacuation plans, and mitigating risks to nearby communities. Additionally, studying volcanic activity in remote areas can provide valuable insights into the Earth's geological processes and volcanic behavior.
What are the primary impacts of sakurajima?
The primary impacts of Sakurajima, an active volcano in Japan, include frequent eruptions that result in ash fall, pyroclastic flows, and lava flows. These eruptions can disrupt air travel, affect local agriculture, and pose risks to nearby communities. Sakurajima's activity is closely monitored to ensure the safety of residents and visitors in the area.
Does hot lava become rock or soil?
It cools to form igneous rock, which over time may be eroded down to become a component of the soil. The larger contributor to rich soil around volcanoes is the ash which settles after an eruption.
How does volcanic activity affect the formation of volcanic rock?
Volcanic activity heats up and melts existing rock beneath the Earth's surface, creating molten magma. This magma is then forced to the surface through volcanic eruptions, cooling and solidifying to form volcanic rocks such as basalt, andesite, or rhyolite. The specific composition and characteristics of the volcanic rock depend on factors like the type of magma, eruption style, and cooling rate.
Arenal Volcano in Costa Rica has been in a resting phase since 2010, with no recent eruptions or significant volcanic activity. It is still considered to be an active volcano, but it is closely monitored by scientists for any signs of potential activity.
Mount Unzen is not located on a hot spot. It is a volcano in Japan situated on the island of Kyushu, which is part of the Ring of Fire, a region known for frequent volcanic and seismic activity due to the movement of several tectonic plates.
Which boundaries are likely to result in volcanic island arcs?
Volcanic island arcs are likely to result from convergent boundaries where an oceanic plate subducts beneath another oceanic plate or a continental plate. The subducted plate can melt, causing magma to rise and form a series of volcanic islands above the subduction zone.
Where is mount hibok-hibok located?
Mount Hibok-Hibok is located on Camiguin Island, part of the Philippines. It is an active stratovolcano in the northern Mindanao region.
Is the silica content in igneous rock of low viscosity?
Different igneous rocks have different silica contents. I could go into loads of detail about mineralogy but what you probably need to know is that magma (as rock is immeasurably viscous as it is solid) containing high Si is more viscous that that with low Si (Silicon being Si). Basalt has low Si, andesite has high Si. Both are extrusive igneous, but form at different plate boundary types.
How many times mt paricutin erupted?
Mount Paricutin erupted only once, starting on February 20, 1943, and continuing until 1952. It is considered one of the most famous and unique volcanic eruptions in history due to its sudden formation in a cornfield.
How is it possible for magma to have a higher silica content than the rock from which it was formed?
Magma could have higher silica content than its parent rock, if during melting or movement it is gets in contact with silicic country rocks and absorbs them. This is reffered to as Assimillation.
Is it likely for the Olympus Mons to erupt in front of tourist?
Seeing as Olympus Mons is on Mars, and there won't be any tourists on Mars for quite some time, answer would have to be NO.
Mars is also likely geologically dead at this point, so it is unlikely that Olympus Mons will ever erupt again. (Though, recent data suggests that Mars may not be dead yet.)
What is the viscosity of lava flow from a cinder cone volcano?
The viscosity of lava flow from a cinder cone volcano is typically high, leading to slower-moving lava flows. This is due to the higher silica content of the lava, which increases its viscosity. As a result, cinder cone volcanoes often produce short, thick flows that can cool and solidify quickly.
What reference source largest volcanoes in the world?
I think you mean a reference source for the space view of volcanoes, THE source is the ASTER (acronym for Advanced Spaceborne Thermal Emission and Reflection Radiometer) Volcano Archive (AVA) hosted by NASA's JPL.
There you find a link to the alphabetic listing of volcanoes, containing practically every volcano in the world, even officially unnamed ones, and another link to Google Maps where you can browse the globe (each volcano clearly marked). For each volcano you will find the entry of the Smithsonian volcano catalog and ASTER Very Near Infrared (VNIR) daytime satellite images (updated regularly containing old ones and very recent ones; a total of 40,000 photos).

What is a shield volcanoes shape and size?
A shield volcano can range in size depending on scale, but in height they are relatively low compared to diameter. They have shallow slopes. They are shaped, as the name suggests, like round shields of the classical world.
Do volcanoes occur anywhere other than at subduction zones?
Volcanoes exist on every continent on Earth, and even under the ocean. They also exist on other planets, such as Olympus Mons on Mars.
Volcanoes tend to exist along the fault lines of tectonic plates, where the Earth's magma core more easily penetrates the Earth's crust.
What are the top 5 tips for preparing for a surviving a volcanic eurptions?
Is active or inactive volcano Taal Volcano?
Taal Volcano is an active volcano located in the Philippines. It is one of the most active volcanoes in the country and has had several eruptions in recent history, with the most recent one occurring in January 2020.
How might a volcano be hazardous for plants and animals that live nerby?
Lava flows from vents, setting fire to and often burring everything in its path, it also belches out a mixture of dangerous materials this can burn trees and plants, also bury and kill animals and it affects their environment.
How might plants have arrived on surtsey?
Plants likely arrived on Surtsey through wind dispersal of seeds, floating of plant material from neighboring islands, or transportation by birds. It is possible that some plant seeds were also brought to the island by researchers or accidental human activity.

Does Mars have lava plains like the lava flows on Earth's moon?
Yes, Mars has lava plains similar to those found on Earth's moon. The largest volcano on Mars, Olympus Mons, is believed to have been formed by extensive lava flows. These lava plains contribute to Mars' diverse surface features.
