Are fissure eruptions explosive?
A fissure vent, also known as a volcanic fissure, eruption fissure or simply a fissure, is a linear volcanic vent through which lava erupts, usually without any explosive activity.
What do fissure eruptions look like?
Fissure eruptions are quiescent, and the height of the airborne eruptive material is small, often only a few tens of meters. The basaltic fragments in the curtain of fire thus remain largely liquid when they hit the ground. These coherent lumps of hot, fluid lava are called spatter.
What do you call a steep hill that has sticky fragmented lava?
Answer: A volcanic cone is a hill-shaped landform that forms around a volcano. Volcanic cones can be steep or gently sloping depending on the type of eruption that forms them.
What type of volcano has a steep conical hill of volcanic debris deposited around a volcanic vent?
pyroclastic cone hill created by tiny bits of lava blown out of a volcano and fallen down around the volcanic vent. Also called a cinder cone.
Which volcanoes have high eruptive force?
Composite volcanoes are some of the most dangerous volcanoes on the planet. They tend to occur along oceanic-to-oceanic or oceanic-to-continental boundaries because of subduction zones. They tend to be made of felsic to intermediate rock and the viscosity of the lava means that eruptions tend to be explosive.
Why are volcanoes cone-shaped?
They form when different types of eruptions deposit different materials around the sides of a volcano. Alternating eruptions of volcanic ash and lava cause layers to form. Over time these layers build up. The result is a cone that has a gentler slope than a cinder cone but is steeper than a shield volcano.
Which do you think is the most attractive volcano cone?
Answer: Mayon Volcano is the most attractive volcanic cone for me because Mayon Volcano is praise for its symmetry and outstanding conical shape,by far the one of the most beautiful and photographed volcanoes on Earth.
