Essay On Volcano Activity

Introduction A volcano is a location on the surface of the Earth where magma has erupted out of the interior of the planet. Magma is molten rock, which has melted from the extreme heat (2200°C to 5000°C) and pressure that the Earth’s surface, it is called lava. As lava spreads on the surface, it cools and becomes solid rock again. The buildup of lava forms hills and mountains on land, and it forms islands if the volcano began on the ocean floor. The Hawaiian Islands, for example, exists because of volcanoes.
Volcano Facts
1. Volcanoes are mountains that are on the Earth’s surface.
2. When volcanoes erupt, rocks and other fragments shoot up through the volcanos opening, and lava spills out of the volcanos.
3. A 20-mile radius is the most dangerous area a

The most deadly volcano eruption occurred in Indonesia. Tens of thousands lives were lost to no food, tsunamis, ash flows, and mud flows.

Stages of Volcanic Activity We will be talking about the three stages of volcanic activity the Eruption Stage, the Cooling, and the Inactive Stage.
Eruption Stage The first part of the Eruption stage is the invasion of magma. Magma forms when rocks melt in the Earth’s crust. Then it builds up pressure in the magma chamber. Next, the magma in the volcano, gases will be trapped because it is thick and sticky. When the pressure builds up it can cause an explosive eruption. When the volcano explodes the lava flows down the volcano.
Cooling Stage When liquid magma explodes out of a volcano it turns into a solid rock, while it is cooling. An igneous rock is a rock that is made from magma. Lava slowly cools because lava is a poor guide of heat. Lava slowly goes down and gets thicker as it hardens.
Inactive Stage A dormant volcano is a volcano that hasn’t erupted in the past 10,000 years. But it might erupt again. Some examples of dormant volcanos are Mount Kilimanjaro, Four-peaked Mountain, and Mount Meager. An extinct volcano that no one ever thinks it will not erupt
