Why is there different types of volcano?
Why is there different types of volcano?
When magma erupts at the surface as lava, it can form different types of volcano depending on: the viscosity, or stickiness, of the magma. the amount of gas in the magma. the composition of the magma.
How are volcanoes created what are the 3 main types?
Individual volcanoes vary in the volcanic materials they produce, and this affects the size, shape, and structure of the volcano. There are three types of volcanoes: cinder cones (also called spatter cones), composite volcanoes (also called stratovolcanoes), and shield volcanoes.
What are the 3 classification of volcano?
Volcanoes are classified as active, dormant, or extinct. Active volcanoes have a recent history of eruptions; they are likely to erupt again.
What are 3 different types of volcanoes for kids?
What are the different stages of volcanoes? Scientists have categorized volcanoes into three main categories: active, dormant, and extinct. An active volcano is one which has recently erupted and there is a possibility that it may erupt soon.
What are the 3 types of volcanoes describe the differences between each type?
There are three main types of volcano – composite or strato, shield and dome. Composite volcanoes, sometimes known as strato volcanoes, are steep sided cones formed from layers of ash and [lava] flows. When composite volcanoes erupt they are explosive and pose a threat to nearby life and property.
How are volcanoes different from each other?
Volcanoes differ in appearance because of the composition of their magma and the processes that originally created them. The tall cone shape you usually think of when you think of a volcano describes a composite volcano, one common form of volcanoes.
What are the differences between the three types of volcanoes?
Size Differences 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 different types of volcanic eruption how do they differ?
There are two types of eruptions in terms of activity, explosive eruptions and effusive eruptions. Explosive eruptions are characterized by gas-driven explosions that propels magma and tephra. Effusive eruptions, meanwhile, are characterized by the outpouring of lava without significant explosive eruption.
What is the difference between the three types of volcanoes?
The Difference Between the Three Types of Volcanoes Composite volcanoes are explosive, towering giants. Shield volcanoes quietly produce broad, massive structures through lava flows. Cinder cone volcanoes are the smallest and simplest, but still pack a volcanic punch.
What are the different types of volcanoes ks2?
Shield volcanoes are the biggest type and have large, gentle slopes. Stratovolcanoes, which are also called composite volcanoes, are large and often have steep slopes. A caldera volcano is big, round, and shaped like a cauldron. The fourth type of volcano is called a cinder cone, which forms a straight, steep mound.
How do different types of volcanoes vary in appearance and eruption?
