Volcanic Landforms -II
Have you ever thought about how new land appears on Earth? One way this happens is through volcanic eruptions.
When volcanoes erupt, molten rock called lava is released onto the Earth's surface. As the lava cools and solidifies, it creates new landforms.
These volcanic eruptions also happen underwater. When lava erupts beneath the ocean, it cools quickly upon contact with water, creating new land that may eventually rise above the surface.
The Hawaiian Islands are an example of this. These islands are made of shield volcanoes, which produce fluid lava that spreads out in layers.
Over time, as more lava flows and hardens, the island grows larger, adding new land along the coast.
Not all landforms result from surface eruptions. Deep underground, magma cools slowly and hardens into giant rock formations called intrusions. If erosion or natural forces expose them, they create unique landscapes.
The Sierra Nevada mountain range in California is a perfect example. These mountains formed from granite intrusions that became visible over millions of years through geological changes.
