Jika ada satu momen paling dramatis dalam sejarah planet kita, maka tabrakan asteroid raksasa 66 juta tahun lalu adalah salah satunya. Peristiwa ini bukan hanya mengakhiri kejayaan dinosaurus, tetapi juga membentuk ulang kehidupan di Bumi—membuka jalan bagi munculnya mamalia, dan pada akhirnya… kita. Jadi, di mana sebenarnya lokasi bekas hantaman asteroid yang legendaris itu? Jawabannya ada di Chicxulub, sebuah wilayah yang terletak di Semenanjung Yucatán, Meksiko. Kawah yang dihasilkan asteroi...

penjelasan 👇👇 Asteroid Chicxulub Sekitar 66 juta tahun lalu, sebuah asteroid berukuran sekitar 10–15 km menghantam Bumi di wilayah yang sekarang menjadi Semenanjung Yucatán, Meksiko. Asteroid tersebut bergerak dengan kecepatan sekitar 20 km/detik sebelum menghantam permukaan. Tumbukan ini membentuk Kawah Chicxulub, yang memiliki diameter sekitar 180 km. Energi tumbukannya diperkirakan mencapai sekitar 10²³ joule. Besarnya energi tersebut menyebabkan perubahan lingkungan dalam skala global. #A

Sistema Sac Actun adalah sistem gua bawah air yang terletak di sepanjang pantai Karibia di Semenanjung Yucatán dengan jalur ke utara dan barat kota Tulum. Penemuan koneksi ke Sistema Dos Ojos pada tahun 2018 menjadikannya sistem gua bawah air terpanjang yang diketahui. Pada Januari 2023, ini adalah sistem gua bawah air terpanjang kedua di dunia, hanya dilampaui oleh Sistema Ox Bel Ha. Sisa-sisa dari bukti tertua keberadaan manusia di benua Amerika telah ditemukan di da...

penjelasan . . . . Kawah Chicxulub saat ini terkubur di bawah Semenanjung Yucatán, Meksiko, sebagian di daratan dan sebagian di bawah laut, dengan batasannya ditandai oleh cincin cenote , tidak terlihat langsung sebagai kawah besar di permukaan, dan ditutupi oleh lapisan batuan serta sedimen tebal hasil dari jutaan tahun. Ilmuwan mempelajari sisa-sisa kawah ini dengan mengebornya untuk memahami dampak asteroid yang memusnahkan dinosaurus 66 juta tahun lalu. Ciri-ciri Ch...
