What is this answer True or false all volcanoes at some point can erupt even if it was dormant for a long time?
True. All volcanoes have the potential to erupt again, even if they have been dormant for long periods. Dormant volcanoes can become active again due to changes in geological conditions, such as the movement of magma beneath the surface. However, predicting exactly when a dormant volcano will erupt can be challenging.

What is erupted volcano called?
The second eruption is called a reawakening or re-eruption.Most volcanoes erupt multiple times over the course of their lifespan; the period during which a volcano doesn't erupt is called its dormant period or dormancy.
Which volcanoes have erupted before?
Some well-known volcanoes that have erupted in the past include Mount Vesuvius in Italy, Mount St. Helens in the United States, Mount Krakatoa in Indonesia, and Mount Pinatubo in the Philippines. These volcanoes have had significant eruptions that have impacted their surrounding areas and sometimes even global climate.
Why do people still live dangerously near volcanoes?
People living near a dormant volcano may be unaware of the danger. A dormant volcano may become active at any point of timeand the people living near the volcano may not realize it is about to erupt.
Is mt fuego active or dormant?
Mount Fuego in Guatemala is an active volcano. It has frequent eruptions and is one of the most active volcanoes in Central America.
What is the difference from a non volcano and active volcano?
Effusive eruptions occur when hot, (1200oC) runny basalt magmas reach the surface. Dissolved gases escape easily as the magma erupts, forming lava that flows downhill quite easily. Effusive eruptions build up gently-sloping Shield Volcanoes like Hawaii. Explosive eruptions occur where cooler, more viscous magmas (such as andesite) reach the surface. Dissolved gases cannot escape as easily, so pressure may build up until gas explosions blast rock and lava fragments into the air! Lava flows are much more thick and sticky so do not flow downhill as easily. These eruptions build up more steeply-sloping Composite volcanoes like this one in Chile.
Why might people living near dormant volcanoes be unaware of the danger?
People living near a dormant volcano may be unaware of the danger. A dormant volcano may become active at any point of timeand the people living near the volcano may not realize it is about to erupt.
Do all volcanos erupt?
no all the volcanoes do not erupt.there are three types of volcanoes extinct,average and active. no because there are dome mountains that do not erupt and they are full of lava and they will erupt in more or less than 300 years.
What is erupted volcano called?
The second eruption is called a reawakening or re-eruption.Most volcanoes erupt multiple times over the course of their lifespan; the period during which a volcano doesn't erupt is called its dormant period or dormancy.
Why did the Yellowstone volcano erupt?
It will erupt for the same reason that all volcanoes erupt: magma is collecting in the magma chamber and pressure is increasing. This will eventually reach a breaking point and result in an eruption. The chances of that occuring in our lifetimes however, are very small.

Can cold lava ever come out of an active volcano?
Not from any volcano on Earth. Volcanoes on Earth erupt molten rock, which has a rather high melting point. The "coldest" lava on Earth is the carbonatite lava of Ol Doinyo Lengai in Tanzania which erupts at temperatures of 500-600°C (930-1100°F). However, some icy moons of the outer solar system may have cryovolcanoes. Instead of lava, these volcanoes erupt an extremely cold mixture of water, ammonia, methane, and other volcatiles.
Why are some volcanoes more dangerous than others?
Yes. There are active volcanoes that does not affect any one to this date. There has been others that has wiped out an entire civilization such as the case of the pompeian civilization completely devastated by a volcano.
Where does magma erupt through the crust?
Magma erupts through the crust at volcanic vents, which are openings in the Earth's surface where molten rock, gases, and ash are expelled during volcanic eruptions. These vents can be found at various locations such as at mid-ocean ridges, subduction zones, and hotspot volcanoes.
How do volcanoes erupt in glaciers in countries like Iceland when they are so cold?
Volcanoes in glaciers, like those in Iceland, can erupt due to geothermal activity, where the magma's heat melts the ice above it. The interaction between magma and ice can lead to explosive eruptions, producing ash, steam, and meltwater flows. The cold temperatures can also create a rapid cooling effect on the lava, forming glassy volcanic rocks called "tuff."
