Deccan Trap' is formed through

Question

Accepted Answer

Deccan Trap' is formed through **Besalt**

**Explanation:**

The Deccan Traps are a large igneous province located on the Deccan Plateau of west-central India. They are one of the largest volcanic features on Earth. The Deccan Traps were formed by massive volcanic eruptions that occurred approximately 66 million years ago, near the Cretaceous–Paleogene boundary. These eruptions poured out vast quantities of lava over a relatively short period.

*   **Why Basalt (Option 4) is Correct:** The lava that erupted during the formation of the Deccan Traps was primarily basaltic in composition. Basalt is a dark-colored, fine-grained extrusive igneous rock formed from the rapid cooling of lava exposed at or very near the surface of a planet or moon. The Deccan Traps are composed of multiple layers of solidified basalt lava flows, stacked one on top of the other. The characteristic stepped (or "trap") appearance of the region is due to the differential weathering of these basalt layers.

*   **Why the other options are incorrect:**

*   **Granite (Option 1):** Granite is a coarse-grained, intrusive igneous rock. This means it forms deep underground from slowly cooling magma. Granite is not associated with the volcanic eruptions that created the Deccan Traps.

*   **Sandstone (Option 2):** Sandstone is a sedimentary rock formed from cemented sand grains. It has nothing to do with volcanic activity or lava flows.

*   **Gneiss (Option 3):** Gneiss is a metamorphic rock formed when other rocks (like granite or shale) are subjected to high heat and pressure. It is not directly related to the volcanic origin of the Deccan Traps.
