Every aggregation and division of supercontinents in history has a profound impact on the entire Earth system. Many hypotheses link supercontinents to events such as climate change and life evolution that have occurred in Earth's history.
For example, some scientists have suggested that the supercontinent of Rhodinia was cracked due to a super mantle plume event 800 million years ago, producing a large area of basalt. Basalt is more easily weathered than other rocks. During the weathering process, it absorbs a large amount of carbon dioxide from the atmosphere, which rapidly reduces the carbon dioxide content in the atmosphere, causing the earth to produce an "ice chamber effect." The decline in the earth's temperature may further drive the "glacier catastrophe", causing the climate to lose control and eventually forming a global ice age event about 720 million years ago. The earth at this time is also called the "Snowball Earth."
Some scientists have suggested that more than 500 million years ago, when the Gondwana continent was formed, large-scale orogeny would bring large amounts of nutrients such as iron and phosphorus to the oceans in the equatorial region. This has undoubtedly greatly stimulated the prosperity of marine microorganisms and algae. Through photosynthesis, they absorb large amounts of carbon dioxide and release oxygen, greatly increasing the oxygen content in the atmosphere. The abundant nutrients and the increase in atmospheric oxygen content are extremely beneficial to the reproduction of life on earth, providing the most basic guarantee for the "Cambrian explosion of life" during this period.
