If they are very hot it is because the ash had been molten lava just a while ago.
However ash often cools quickly due to its large surface area compared to a bomb or block, which remain hot much longer.
lower magma reserves or the volcano tube has closed/shifted.
It will plug up the volcano, which will usually keep the volcano from erupting for about 100 years. However, after that, the entire volcano itself will explode.
A caldera usually is no warmer than the surrounding land. A caldera is a depression formed when a volcano collapses in a cataclysmic eruption, but if it isn't erupting or has not erupted very recently, then it will not be unusually hot, with the possible exceptions of hot springs.
VERY hot
Some volcano words are: boiling hot lava molten metamorphic rock erupting tall volcano(of course)
They can be either. Most of the time a volcano is not actively erupting. So the temperature mostly depends on what the weather is. Even during small eruptions, lava and gasses do not heat most the outside of the volcano very much.
An erupting hot spring occurs when pressure builds up underground, causing a sudden release of steam, water, and rocks. This eruption can be triggered by changes in temperature or other geological factors. Erupting hot springs are natural phenomena that can be dangerous if not approached with caution.
The hazards of a volcano can be quite serious. For example, the lava which is extremely hot and can burn you to death. The volcanic ash goes into your lungs when you breath in and when a volcano erupts, it may cause earthquakes. I hope this answer helps!!!
It is usually around 2,000 degrees Fahrenheit.
A caldera is a large depression in the ground that forms when a volcano produces a very large eruption. So much magma is drained from below that the volcano collapses into the space left behind. A caldera that is erupting or has just erupted may contain hot ash, lava, or cinders from the eruption. Others may have hot springs as water is heated by hot rocks below ground. Otherwise you will not find any abnormal temperatures in a caldera.
Generally, yes. When a volcano is dormant the temperatures are generally no different from what you would find on a non-volcanic mountain. One exception would be the occasional hot spring or fumarole venting hot gas.
Snow can accumulate on the higher elevations of volcanoes where temperatures are colder, even while the volcano is erupting. The heat from the eruption may melt the snow temporarily, but since snowfall continues at higher altitudes, it can still accumulate on the volcano. Additionally, volcanic ash and debris can cool the surrounding area, allowing the snow to remain despite the heat from the eruption.
