Why is it proposed that continental drift increases ocean biodiversity?

How does continental drift affect oceans?

Continental drift closed an oceanic gateway that once connected the Atlantic and Pacific Oceans, creating the Isthmus of Panama. The continental shift led to changes in ocean circulation and Earth’s climate.

How do you think the movement of the continents affects the environment and ecosystems?

In 1970, James Valentine and Eldridge Moores of the University of California suggested that broken-up continents would create more ecological niches and promote favorable climate and environmental conditions that are conducive to biodiversity. …

How does continental climates change as a result of continental drift?

Continental motion via the movement of tectonic plates can affect earth’s climate by changing the sizes and locations of both land masses and ice caps, and by altering ocean circulation patterns, which are responsible for transporting heat around the earth, which in turn affect atmospheric circulation processes.

What proves continental drift?

The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones.

Why was the continental drift theory replaced by plate tectonics?

Wegener’s theory has now been replaced by the theory of plate tectonics – an extension of continental drift theory that suggests continents migrate due to the movement of the tectonic plates on which they lie.
