960 - How do volcanic eruptions occur, and what are their effects on the environment?
Imagine the Earth is like a big ball with layers of liquid rock called magma inside. When magma builds up pressure and gets too hot, it tries to escape through a volcanic vent or crater. This is called a volcanic eruption.
Here's what happens during an eruption:
- Magma rises to the surface, often causing the ground to shake.
- When the magma comes out, it's released as lava, ash, and gas.
- The lava flows out and can create new land, while ash and gas go into the air, blocking sunlight.
Effects on the environment:
- Ash can pollute the air, water, and soil, making it hard for plants and animals to survive.
- Lava can burn everything in its path and change the landscape.
- Ash and lava can also affect the climate, making it cooler or warmer.
- Volcanic eruptions can also create new land and habitats for plants and animals.
So, volcanic eruptions are both powerful and important natural events that shape our planet.
