Rotakasi Bumi Melambat? This is fact

February 16, 2025 By earthnowadmin

Some know that Bumi rotasi isn’t always the same. Rotasi Bumi justru bisa melambat dan diputar lebih cepat. Lantas how?
We know that Bumi rotasi is peredaran Bumi on poros or sumbunya. While rotating, Bumi will go from left to right or turn left to right.

Rotation Bumi lasts 23 hours 56 minutes or 24 hours 4 minutes for each putaran. In this Bumi Rotation, the atmosphere that selects the bumi will also rotate.

Rotation of the body can cause several problems in makhluk life. Examples include siang-malam, different times in different regions, gerak all day, air Laut airflow, and Bumi gravity speed.

According to BBC Science Focus, scientists define a day as 86.400 days or 24 hours. This also requires Bumi to berotasi once.

Rotasi Bumi justru can melambat till its daily average is 1.8% million dollars per year. That is, 600 million years ago, one day lasted 21 hours.

Alastair, astronom ologist at Pusat Astrofisika Jodrell Bank di Universitas Manchester, said, “Variasi panjang hari ini disebabkan oleh beberapa faktor, yaitu efek pasang surut Bulan dan Matahari, penggabungan inti-mantel di Bumi, dan distribusi massa secara keseluruhan di planet

In addition, seismology, glasiasi, cuaca, lautan, and magnetism can affect daily life.

Though called melambat, scholars have found opposites. In 2020, researchers found that Bumi justru berputar faster.

According to them, Bumi berputar faster than before in 50 years. Actually, all 28 days of terpendek happened in 2020.

Even so, until now, scientists don’t know what causes Bumi’s rising laju rotasi.

Some scientists believe this is caused by gletser during ke-20 or air accumulation in large reservoirs in the Bumi utara.

However, according to the author, this perception is only temporary and Bumi will begin to change with time.

In a June 2024 study, gelombang and serupa variables were considered, affecting inti at different times.

Seismogram data from gempa and ledakan berulang in Bumi shows that inti rotation at the center of the island is rapidly decreasing compared to Bumi’s surface over the past few years.

According to new studies in Nature, a factor that can increase Bumi rotation and slow its perception beyond its cair is a dramatic kutub.

This happens due to rising global temperature. Airflow causes massive mass redistribution on Earth, slowing rotation.

Interaction with other factors that slow planet rotation can also change how people in the Bumi adjust time.

“Hanya dalam beberapa tahun, kita mungkin harus melakukan penghapusan “detik kabisat” untuk pertama kalinya,” said Scripps Institution of Oceanography geogeologist Duncan Agnew.

“Ini adalah salah satu hal yang ‘belum pernah terjadi sebelumnya’ yang kita lihat dari pemanasan global: gagasan bahwa efek ini cukup besar untuk mengubah rotasi seluruh bumi,” ya.

Agnew found that pencairan-induced delays effectively compensate for Bumi-induced slowdowns. One day was 0,0025 detik smaller than 50 years ago.

If global warming doesn’t happen, humans may need to finish a book faster. Because to pemanasan, this kabisat detik was completed in 2028 or 2029, against his predictions.
