how does cinder cone volcano flows?
please help
To understand how a cinder cone volcano flows, we need to consider two important factors: the eruptive style and the characteristics of cinder cone volcanoes.
1. Eruptive Style: Cinder cone volcanoes typically have explosive eruptions that are driven by a high gas content in the magma. This gas exerts pressure and causes the magma to explode into the air.
2. Characteristics of Cinder Cone Volcanoes: Cinder cones are small, steep-sided volcanoes composed of loose, fragmented rock called cinders. They are formed by a buildup of pyroclastic materials, such as ash, lapilli (small rocks), and volcanic bombs, ejected from the volcano during explosive eruptions. These materials accumulate around the vent and form a conical shape.
Now, let's explore the flow of a cinder cone volcano step by step:
1. Eruption: When a cinder cone volcano erupts, the highly pressurized magma is expelled forcefully into the air. This explosive eruption hurls volcanic ash, cinders, and other pyroclastic materials into the surrounding area.
2. Pyroclastic Flow: During the eruption, some of the denser volcanic materials, such as large cinders and volcanic bombs, fall back to the ground around the vent area. This accumulation of materials forms the characteristic steep slopes of the cinder cone.
3. Ash Clouds and Ash Fall: Meanwhile, the lighter volcanic ash and smaller volcanic particles get carried away by the wind. These materials may travel long distances, depending on the strength and direction of the winds. The ash can cause ash fall in the surrounding areas, covering the landscape with a layer of fine particles.
4. Lava Flows: While cinder cone eruptions are mainly explosive, some lava may also be produced. However, the lava flows associated with cinder cone volcanoes are typically limited in size and extent compared to other types of volcanoes. These lava flows are often short and don't extend far from the vent.
In summary, the flow associated with a cinder cone volcano primarily includes explosive eruptions, the deposition of pyroclastic materials around the vent, ash cloud dispersal, and the limited flow of lava. It's important to note that the primary characteristic of cinder cone volcanoes is their steep slope and the accumulation of cinders and other pyroclastic materials rather than extensive lava flows.
