Un equipo internacional de geocient\u00edficos <\/strong>ha publicado un estudio que revela un hallazgo significativo: la rotaci\u00f3n de la Tierra se est\u00e1 ralentizando,<\/strong> un proceso que ha ocurrido durante \u201cvarios millones de a\u00f1os\u201d. Los investigadores identificaron que esta desaceleraci\u00f3n sigue un patr\u00f3n escalonado, <\/strong>marcado por dos per\u00edodos de estabilidad importantes, uno coincidiendo con la diversificaci\u00f3n de la vida en la Tierra y el otro con un proceso de extinci\u00f3n masiva.<\/p>\n\n\n\n

La Tierra gira cada vez m\u00e1s lento: detalles del estudio<\/mark><\/strong><\/p>\n\n\n\n

Seg\u00fan Phys.org<\/em>, investigaciones anteriores hab\u00edan demostrado que la velocidad de rotaci\u00f3n de la Tierra disminuye, en parte debido a la disipaci\u00f3n de las mareas. Sin embargo, los registros no siempre han sido consistentes. Para llegar a las conclusiones del presente estudio, los cient\u00edficos analizaron muestras de sedimentos con 650 millones de a\u00f1os de antig\u00fcedad. Con ocho conjuntos de datos geol\u00f3gicos recopilados a lo largo de varias d\u00e9cadas, tuvieron acceso a informaci\u00f3n hist\u00f3rica sobre la evoluci\u00f3n geogr\u00e1fica y rotacional de la Tierra.<\/p>\n\n\n\n

Las evidencias mostraron que la desaceleraci\u00f3n de la rotaci\u00f3n terrestre no ha sido uniforme<\/strong>. En lugar de un proceso suave y gradual, la Tierra ha experimentado per\u00edodos de desaceleraci\u00f3n seguidos de estabilidad, lo que define el mencionado \u201cpatr\u00f3n escalonado\u201d.<\/p>\n\n\n\n

Uno de estos per\u00edodos de estabilidad coincidi\u00f3 con la explosi\u00f3n c\u00e1mbrica, un evento que provoc\u00f3 un aumento masivo en la diversidad de vida en la Tierra. El otro ocurri\u00f3 durante \u201cla gran mortandad\u201d, la mayor extinci\u00f3n masiva registrada, al final del per\u00edodo P\u00e9rmico, que result\u00f3 en la desaparici\u00f3n de aproximadamente el 96% de las especies marinas y el 70% de las especies terrestres. Con excepci\u00f3n de la era contempor\u00e1nea, en la que los humanos han alterado el medioambiente, los datos indican que la desaceleraci\u00f3n se debi\u00f3 principalmente a la disipaci\u00f3n de las mareas y la energ\u00eda orbital y rotacional transformada en calor en la superficie de la Tierra.<\/p>\n\n\n\n

El estudio, publicado en Proceedings of the National Academy of Sciences<\/em>, tambi\u00e9n se\u00f1ala que, durante el per\u00edodo analizado, la Luna se ha alejado unos 20.000 kil\u00f3metros de la Tierra. Adem\u00e1s, los d\u00edas en nuestro planeta eran aproximadamente 2,2 horas m\u00e1s largos en el pasado.<\/p>\n\n\n\n
