Supercontinents in a sentence

Because Pangaea is the most recent of Earth's supercontinents, it is the most well known and understood.

During the accumulation of supercontinents with times of regional uplift, glacio-epochs seem to be rare with little supporting evidence.

However, the lack of evidence does not allow for the conclusion that glacio-epochs are not associated with collisional assembly of supercontinents.

Influence on paleoclimate and life Unlike later supercontinents, Rodinia would have been entirely barren.

In general the interaction of supercontinents and climate is similar to the interaction between present-day continents and climate, just on a different scale.

It is thought that the Earth's oxygen content has risen in stages: six or seven steps that are timed very closely to the development of Earth's supercontinents.

On time scales lasting hundreds of millions of years, the supercontinents have formed and broken up three times.

Orogenic belts can form during the assembly of continents and supercontinents.

Pangaea's supercontinent cycle is a good example for the efficiency of using the presence, or lack of, these entities to record the development, tenure, and break-up of supercontinents.

Supercontinental climate Continents, in particular large or supercontinents, will affect the climate of the planet drastically.

Supercontinents have a larger effect on climate than do continents.

Supercontinents have assembled and dispersed multiple times in the geologic past (see table).

Tectonic history (Supercontinents) Evidence of collision and rifting between continents raises questions as to what exactly the movements of the Archean cratons composing Proterozoic continents were.

The breakup of supercontinents may have affected local precipitation.

The effects of mantle plumes possibly caused by slab avalanches elsewhere in the lower mantle on the breakup and assembly of supercontinents.

The process of Earth's increase in atmospheric oxygen content is theorized to have started with continent-continent collision of huge land masses forming supercontinents, and therefore possibly supercontinent mountain ranges (supermountains).

There is an association between the rifting and breakup of continents and supercontinents and glacio-epochs.

This causes the continents to push together to form supercontinents and was evidently the process that operated to cause the early continental crust to aggregate into Protopangea.

This may be due to high seafloor spreading rates after the breakup of Precambrian supercontinents and the lack of land plants as a carbon sink.
