Step 1: Recall the configuration of supercontinents.
During much of the Mesozoic Era, the Earth's landmass was divided into two supercontinents: Laurasia in the north and Gondwana in the south.
Step 2: Locate the Tethys Sea.
The Tethys Sea was a vast ocean that separated Laurasia from Gondwana.
Step 3: Identify the modern continents derived from Laurasia and Gondwana.
- Laurasia included most of what is now North America and Eurasia.
- Gondwana included South America, Africa, Antarctica, Australia, and India.
Step 4: Conclude the position of the Tethys Sea.
The Tethys Sea was situated between the landmasses that would become Eurasia and Africa. The eventual collision of the African and Eurasian plates closed the Tethys Sea and formed the Alpine-Himalayan mountain range.
