Question

Six hundred and fifty million years ago, a giant amalgamated southern supercontinent — Gondwana — did indeed exist, centred roughly around present-day Antarctica. Things were quite different then: humans hadn't arrived on the global scene, and the climate was much warmer, hosting a huge variety of flora and fauna. For 500 million years Gondwana thrived, but around the time when the dinosaurs were wiped out and the age of the mammals got underway, the landmass was forced to separate into countries, shaping the globe much as we know it today.

When was Gondwana forced to separate into countries?

पर्याय

• When dinosaurs were wiped out and mammals evolved.

• When an earthquake shook the continent.

• When mammals started living on earth.

• When something unusual happened on the continent.

Answer 1

When dinosaurs were wiped out and mammals evolved.

Explanation:

Gondwana prospered for 500 million years, but when the dinosaurs were killed out and the age of mammals began, the landmass was forced to break into countries, establishing the world as we know it today.
