VOLCANO

Volcano is the natural phenomena which occurs due to the pressure inside our earth and errupts in the form of hot molten magma through the cracks.

CAUSES OF VOCANO Pressure: Volacano causes due to the pressure created inside our earth. Magma is a red hot material which is present inside our earth and when it's hotness increses due to the increase in the pressure inside our earth leading hot molten magma to reach earth surface.

TYPES OF VOLCANOES

There are mainly three types of volcanoes based one the period of erruption. They are: 1. ACTIVE OR FREQUENT VOLCANO: Active volcanoes are those which errupts oftenly and frequently. This the reason that active volcanoes are also called as frequent volcanoes. 2. DORMANT OR SLEEPING VOLCANO: These are the volcanoes which do not errupts for a long time but sometimes they errupts suddenly without any alert. 3. EXTINCT VOLCANO: These volcanoes are those which errupted once upon a time and there is no expectation of future erruption. But if at all again it errupts them it could be called as dormant volcano.

DIFFERENT ELEMENTS OF VOLCANO

MAGMA CHAMBER: It is a part or chamber where hot red molten material is stored inside our earth.

VENT: It is a pipe or cracks on our earth surface through which hot molten magma errupts.

LAVA: It is semi liquid which occurs on the earth surface when volcano errupts. The difference between magam and lava is; when this semi liquid material is present inside our earth then it is called magma. When magma occurs on the surface then it is called as lava.

CRATER: It is a round and circled part created at the mouth of the volcano due the erruption of magma.

NEGATIVE EFFECTS OF VOLCANO

Volcano can change the weather. It can bring rain and it can cause thunder, lightening and disturbance in the environment. Volcano causes death to many living things such as: 1. Human beings: Volcano takes away the life of the human beings who are staying in the surrounding area of the volcanic erruption. 2. Flora and Fauna: Volcano not only takes away the life of human beings but also take away the life of animals and plants. If volcano occurs in the sea or an ocean the it kills marine species and leads to water pollution. Air pollution also happens due to the smoke created because of volcanic erruption. The magma is too hot it just burns all the properties also which are around the place where volcano errupts.

POSITIVE EFFECTS OF VOLCANO

Soon after the term volcano most of the people think of negative effects but there are some positive effects too like: The vocanic ash which remains on the earth surface after volcanic erruption is very good for soil. Volcanic erruption makes mountain steep and such region is more suitable for the growth of plants and trees. Many animals make their stay more protected in such region.

CAN WE PREDICT VOLCANIC ERRUPTION?

The scientists who studies on volcano are called as Volcanologists and according to them it is said that, it is possible to predict vocanic erruption through the behaviour of animals and rumbles inside grumbling mountains.

COCLUSION

Volcano is one of the natural phenomena which is more dangerous like any other natural phenomena such as earthquake, tsunami and cyclone etc. Each of these are having their own advantages and disadvantages. In this page itself one will come to know the posive and negative effects of volcano.
