The Paleo-Tethys Sea was a significant ancient ocean that played a crucial role in the separation of major continental landmasses during the Paleozoic and Mesozoic eras.
During geological history, Earth's continents have shifted and broken apart. The Paleo-Tethys Sea acted as a barrier between specific large continental regions.
The Paleo-Tethys Sea specifically separated the northern supercontinent of Laurasia from the southern supercontinent of Gondwanaland.
Therefore, the Paleo-Tethys Sea was the body of water situated between these two major continental blocks.
| Plate boundary Type | Example | ||
| A. | Oceanic Divergent | F. | San Andreas fault |
| B. | Continental Divergent | G. | Himalaya |
| C. | Oceanic-Continental convergence | H. | Mid Atlantic Ridge |

| E. | Transform | J. | Andes |

The above diagram shows a schematic planar configuration of three tectonic plates P-1, P-2 and P-3 and two plate boundaries at a spreading ridge (MOR) and subduction zone. A-B-C is a 1000km long hot spot track formed over a hotspot (HS) and for a period of 40 Myr. The ages of the volcanoes on the track would yield which one of the following relationships against their distances from the current location of the hotspot?
