A Guyot (or seamount) is an isolated, flat-topped submarine mountain. Geographically, they are the plateaus of the ocean floor. They were originally volcanic islands that were leveled by wave erosion at the sea surface and subsequently submerged as the ocean ...
Regur soil, also known as Black Cotton Soil, is formed by the long-term weathering of basaltic rock. In India, this soil is found extensively across the Deccan Plateau, which was formed by ancient volcanic lava flows. The mineral-rich basalt gives ...
A Volcanic Neck (or plug) is a landform created when magma hardens inside the “throat” or vent of an active volcano. Over millions of years, the softer outer layers of the volcanic cone are eroded away by wind and water, ...
The Deccan Traps were formed nearly 66 million years ago by fissure eruptions, where highly fluid basaltic lava flowed out of long cracks in the Earth’s crust. This “flood basalt” covered over 500,000 square kilometers, creating a stepped (trap) landscape. ...
