| is a common eruptive product of submarine volcanoes | Most are at the bottom of the oceans, therefore most volcanic activity is submarine, forming new seafloor |

| The sulfate aerosols also promote complex reactions on their surfaces that alter chlorine and chemical species in the stratosphere | are also considered supervolcanoes because of the vast amount of lava erupted, but they are non-explosive because only non-explosive eruptions such as produce basalt lava |
Volcanic ash that is light enough to be erupted high into the may travel many kilometres before it falls back to ground as a.
2| Vents that issue volcanic material lava, which is what magma is called once it has escaped to the surface, and and gases mainly can be located anywhere on the landform | Tuya Butte was the first such analyzed and so its name has entered the geological literature for this kind of volcanic formation |

| Supervolcanoes are hard to identify centuries later, given the enormous areas they cover | Some volcanoes have rugged peaks formed by rather than a summit crater, whereas others present features such as massive |
Large injections may cause visual effects such as unusually colorful sunsets and affect global mainly by cooling it.

| This collection contains photographs of Mount St | By contrast, volcanoes are usually not created where two tectonic plates slide past one another |
The aerosols increase the Earth's —its reflection of radiation from the back into space - and thus cool the Earth's lower atmosphere or troposphere; however, they also absorb heat radiated up from the Earth, thereby warming the.
