Is lava a volcano part?
Very much so. A volcano is the eruption of molten rock as lava.
Layers of lava emitted by the volcano?
The different layers of a volcano are made from the lava and ash produced by the volcano. Some volcanoes have different thicknesses of layers or only one type of layer depending on the kind of eruption and how much ash it produces.
Does higher magma viscosity lead to more violent eruotions?
Typically, yes. Larger volcanoes such as shield volcanoes erupt more frequently than smaller ones. However, the speed of eruption depends on the type of volcano and lava. If the volcano is an acid-lava volcano or a composite volcano, the eruption may be slow and noisy and the acidic lava is viscous, which means it flows slowly, and that it solidifies up the vent and block the lava from flowing out easily, creating a huge "BANG" during eruptions.
How explosively or quietly a volcano erupts is not affected by?
If a volcano erupts more explosively, the lava spewing out tends to reach farther, possibly ruining a near by town. If it erupts more quietly, not as much lava tends to spew out. However, any eruption will cause harm to the atmosphere because it releases harmful pollutants.
Are areas near the volcano hot or cold?
They can be either. Most of the time a volcano is not actively erupting. So the temperature mostly depends on what the weather is. Even during small eruptions, lava and gasses do not heat most the outside of the volcano very much.

How big does lava can affect?
Lava has a much more intense, but much smaller effect than ash from a volcana eruption. The lava only effects the immediate area around the volcano, because it cools and hardens quickly.
What is a volcanic discharge?
A volcano erupts because there is mass pressure under it. In a volcano there is hot, melted rock called lava. The hot lava produces gasses that build up underground until there is too much for the rock to contain, that makes the eruption. When there is too much, it bursts the volcano. There are two types of eruptions. Non explosive and explosive. When they are explosive, it is caused by clouds of hot debris and gases.

How much magma can cotopaxi can hold?
Cotopaxi volcano is in Ecuador. A volcano magma can be measured during and after volcano eruption. The Cotopaxi eruption in 1987, its lahar has travelled for 60 miles.
When can you say a volcano is in a quiet eruption?
Quiet volcanoes explode with much less suddenness, because lava does not cool and harden. The lava that creates a quiet volcano is still runny and flowing, and do not plug the craters and trap huge quantities of explosive gas. However, pockets of hot gas form that squirt fountains of lava into the air. Because lava flows away before hardening, broad sheets of lava and wide, gently sloping domes are formed around the volcano. When the lava has dried, it forms a rock known as basalt

Contrast magma to lava?
Magma is inside of the volcano and has molten rock in it. To where lava is outside the volcano and does not have as much molten rock in it as Magma does.
