Mengapa Laut mengalami Pasang naik & Pasang Surut? Mengapa pasang tidak sama di semua tempat?

A) Mengapa Laut mengalami Pasang naik dan Pasang surut?
Jika kalian menggerakkan tangan dengan air di baskom, air itu akan naik turun di pinggir baskom. Setelah kalian menghentikan gerakan tangan itu, air dalam baskom masih bergerak untuk beberapa saat. Di pantai, air bergerak naik turun dua kali dalam sehari. Itulah yang disebut pasang naik dan pasang surut. Hal itu terjadi karena pengaruh bulan dan sedikit pengaruh matahari. Keduanya seperti magnet yaitu menarik air ke atas. Jangan kuatir! Air itu tidak dibawa jauh dari planet kita. Perlahan air itu akan kembali segera setelah bulan menghilang dan tidak ada lagi gaya tarik yang bekerja.
B) Mengapa Pasang Naik dan Pasang Surut tidak sama di semua tempat?
Pasang naik dan pasang surut dipengaruhi oleh bulan dan matahari. Bulan berputar mengelilingi bumi dan bumi berputar mengelilingi matahari. Jika dalam perjalanan panjang itu bulan dan bumi berada pada titik yang sama. Keduanya mempunyai gaya tarik yang sangat kuat pada air laut. Air naik dan terus naik. Ketika air turn lagi, garis pantai akan mundur sangat jauh. Akan tetapi, nanti akan kembali seperti semula lagi, terutama di pantai yang sangat besar dan datar. Hanya di laut kecil atau tertutup atau danau yang besar, naik dan turunnya air tidak terlalu besar.

Why Sea experienced Plug & Tidal up? Why not put the same everywhere?

A) Why Put up and the sea had ups and downs?
If you move your hands with water in the basin, the water was goingup and down on the edge of the basin. Once you stop the movement of the hand, the water in the basin is still moving for a while. On the beach, the water moves up and down twice a day. That is calledhigh tide and low tide. It happened because of the influence of the moon and the sun a little influence. Both are like a magnet thatdraws water upwards. Do not worry! The water was not taken awayfrom our planet. Slowly the water will come back as soon as moondisappeared and no longer attractive force that works.
B) Why Put Up and Tidal not the same everywhere?
High tide and tidal influenced by the moon and the sun. Moonrotates around the earth and the earth revolved around the sun. If in the long journey that the moon and the Earth are at the same point.Both have a very strong attractive force in the sea water. The waterkept rising and rising. When the water turn again, the coastline will retreat very far. However, it will be back to normal again, especiallyon a very large and flat. Only in small or enclosed sea or a largelake, the rising and falling water is not too large.
