Label and colour the diagram of an erupting volcano. Location and why they occur.

Here are the labels for the diagram and the explanation for Activity 5.

Activity 4: Label the diagram of an erupting volcano.

• Top cloud: Ash cloud
• Opening at the top: Crater
• Molten rock flowing outside: Lava
• Molten rock inside the volcano: Magma
• Main channel for magma: Vent
• Smaller channel branching off: Side vent
• Outer layer of the Earth: Crust

Activity 5: Location and why they occur.

Volcanoes and earthquakes occur predominantly along tectonic plate boundaries because these are zones where the Earth's large, rigid plates interact. When plates collide, pull apart, or slide past each other, immense stress builds up. This stress is released as earthquakes. The movement of plates can also cause one plate to subduct beneath another, melting rock and forming magma that rises to the surface, leading to volcanic eruptions. The "Pacific Ring of Fire" is a prime example of such a region, where numerous plate boundaries result in frequent seismic and volcanic activity.
