Рассматриваются различные механизмы и темпы роста при формировании Земли. Этот вопрос неразрывно связан с динамикой формирования других планет земной группы и различий в их строении и химическом составе. Формирование Земли и планет земной группы связано с различного рода ограничениями: геохимическими, космохимическими, геологическими, радиоизотопными и др. Показано, что начальное тепловое состояние Земли, определяющее дальнейшую тепловую эволюцию планеты, может служить дополнительным ограничением, накладываемым на механизмы и динамику ее формирования.

Various mechanisms and growth rates during the period of the planet Earth formation are considered. This issue is inextricably linked to the dynamics of other terrestrial planets formation and differences in their structures and chemical composition. The formation of the planets of the Earth group is associated with various kinds of limiting conditions: geochemical, cosmochemical, geological, radioisotope, etc. It is shown that the initial thermal state of the Earth, which determines the further thermal evolution of the planet, can serve as an additional restriction imposed on the mechanism and dynamics of its formation.
