Final answer:
The northern supercontinent formed from the break-up of Pangea is called Laurasia, which includes the Earth's northern continents.
Step-by-step explanation:
The break-up of the supercontinent, Pangea, around 200 million years ago, led to the formation of two smaller supercontinents. The northern supercontinent that emerged from this division is called Laurasia. This supercontinent included what are now the Earth's northern continents. Similarly, the southern supercontinent known as consisted of the Earth's southern continents. The biogeographical patterns we observe today, such as the distribution of the plant family Proteaceae, can be attributed to the existence of these ancient landmasses and the subsequent drift of Earth's tectonic plates.
The fragmentation of the supercontinent Pangea approximately 200 million years ago resulted in the creation of two smaller supercontinents. The northern counterpart formed from this breakup is referred to as Laurasia, encompassing what are now Earth's northern continents. Conversely, the southern supercontinent is known as Gondwana, comprising the Earth's southern continents. The biogeographical patterns observed today, including the distribution of plant families like Proteaceae, can be traced back to the existence of these ancient landmasses and the subsequent movement of Earth's tectonic plates. The separation of Laurasia and Gondwana played a pivotal role in shaping the current distribution of flora and fauna across the planet, as continents drifted and climates shifted over geological time scales. This underscores the profound impact of plate tectonics on Earth's biodiversity and geographical features.
