I added information about the transitions between effusive and explosive eruption patterns. I also reworded the first and second paragraphs of the prior edit, as they were directly plagiarized from other sources. I summarized the information that was plagiarized and cited the original source from which it was copied by the prior author.

An effusive eruption is a type of volcanic eruption in which lava steadily flows out of a volcano onto the ground. It is one of two major groupings of eruptions, the other being explosive. Effusive eruptions form lava flows and lava domes, each of which vary in shape, length, and width. Deep in the crust, gases are dissolved into the magma because of high pressures but, upon ascent and eruption, pressure drops rapidly, and these gases begin to exsolve out of the melt. A volcanic eruption is effusive when the erupting magma is volatile-poor, which suppresses fragmentation, creating oozing magma that spills out of the volcanic vent and out into the surrounding area. Effusive eruptions are most common in basaltic magma, but they also occur in intermediate and felsic magma, and occasionally in silicic magma as well. This video shows lava agitating and bubbling in an effusive eruption of Litli-Hrútur, near the volcano Fagradalsfjall in Iceland, in 2023.
