3. INTRODUCTION
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. Earth's volcanoes occur because its crust is broken into 17 major, rigid tectonic plates that float on a hotter, softer layer in its mantle

4. PARTS OF VOLCANO Magma chamber Vent Crater Lava flow
There are different parts in volcano. We will see some parts of the volcano, they are:-
Magma chamber
Vent
Crater
Lava flow

6. Magma Chamber
A reservoir of magma within the earth's crust beneath a volcano is called as magma chamber.

7. Vent
The magma chamber is a collection of magma inside the Earth, below the volcano. The main vent is the main outlet for the magma to escape. Secondary vents are smaller outlets through which magma escapes.

8. Crater
A volcanic crater is a roughly circular depression in the ground caused by volcanic activity. It is typically a bowl-shaped feature within which occurs a vent or vents. During volcanic eruptions, molten magma and volcanic gases rise from an underground magma chamber, through a tube-shaped conduit, until they reach the crater's vent, from where the gases escape into the atmosphere and the magma is erupted a lava.

10. Lava Flow
Lava flows are the least hazardous of all processes in volcanic eruptions. How far a lava flow travels depends on the flows temperature, silica content, extrusion rate, and slope of the land. A cold lava flow will not travel far and neither will one that has a high silica content.

11. Different types of volcanoes
There are 4 major types of volcanoes:
Cinder Cone Volcanoes
Composite Volcanoes
Shield Volcanoes
Lava Domes
