These include:
- The volume of volcanic products.
- The interval length between eruptions.
- The composition of volcanic products.
- The variety of volcanic eruption types.
- The geometry of the vent.
- The environment into which the volcanic products are erupted.
What are the 3 types of volcano according to its eruptive history?
The Three Classic Types of VolcanoesCinder Cone Volcanoes.Composite Volcanoes (Stratovolcanoes)Shield Volcanoes.
What are the primary factors affecting the volcanoes eruptive style affect the viscosity of magma?
Magma's viscosity depends on how much silica is within its composition. If it has a high concentration, the magma will be thick. These type of volcanoes typically have large explosions with magma moving slowly out.
What are 3 characteristics that determine how violently a volcano erupts?
There are three main factors that influence the violence of a volcanic eruption: magma viscosity, magma temperature, and the number of dissolved gases.
What are the 3 types of volcano according to shape?
The three cone shapes are cinder cones, shield cones, and composite cones or stratovolcanoes.
What are the 3 factors affecting lava viscosity?
The three factors that influence the viscosity of a lava are temperature, the dissolved gases it contains, and its chemical composition.
What factors control eruptive styles of volcanoes?
Eruptive style depends on a set of feedback involving interrelated magmatic properties and processes. Foremost of these are magma viscosity, gas loss and external properties such as conduit geometry.
What are 3 characteristics of a volcano?
Characteristics of volcanoesA volcano is formed by eruptions of lava and ash.Volcanoes are usually cone shaped mountains or hills.When magma reaches the Earth's surface it is called lava. ... Volcanic eruptions can happen at destructive and constructive boundaries , but not at conservative boundaries or collision zones .More items...
What are 3 positive effects of volcanoes?
Positive effects Geothermal energy can be generated in areas where magma lies close to the surface. This is good for increasing renewable energy use. Ash ejected by the volcano acts as a good fertiliser for soils. Volcanoes attract many tourists, who enjoy the dramatic scenery that they produce.
What are the 3 factors affect the earthquake and volcanic activity distribution in the lithosphere?
Answer: The factors that affect the distribution of earthquakes and volcanic activities are plate boundaries, presence of active volcanoes and the place is along a fault line.
What are the 4 primary types of volcanoes?
Different types of volcanoes erupt in different ways. Geologists usually group volcanoes into four main types: cinder cones, composite volcanoes, shield volcanoes, and lava domes. You can learn about some of the different types of volcanoes in order to understand the dangers of volcanoes.
What are 4 different types of eruption styles of volcanoes?
There are four types of eruptions with properties determined mostly by the silica content of magma, and the amount of gas it contains. In order of increasing explosiveness, these are Hawai'ian, Strombolian, Vulcanian, and Plinian eruptions.
What are the 3 types of volcanoes describe the differences between each type?
Cinder cone volcanoes are relatively small, rarely exceeding 1,000 feet tall. Composite volcanoes, also known as stratovolcanoes, are towering structures, often rising more than 10,000 feet. Shield volcanoes are broad, typically 20 times wider than they are high. These volcanoes can be massive.
What are the primary factors that affect the viscosity of magma?
A magma's viscosity is largely controlled by its temperature, composition, and gas content (see downloadable programs at the bottom of this page). The effect of temperature on viscosity is intuitive. Like most liquids, the higher the temperature, the more fluid a substance becomes, thus lowering its viscosity.
Which of the following factors that affects the viscosity of the magma?
Viscosity of Magmas Viscosity depends on primarily on the composition of the magma, and temperature. Higher SiO2 (silica) content magmas have higher viscosity than lower SiO2 content magmas (viscosity increases with increasing SiO2 concentration in the magma).
