Mengapa Pecahan Karang di Air, berduri-duri? Mengapa laut berombak?
(sumber: Rosda Group.1994. Ensiklopedi Laut dan Samudera. Jakarta: PT Rosda Jayaputra.)
A) Mengapa Pecahan Karang di Air?
Jika, perpecahan karang terus menerus dihantam air, bermacam jenis kerang dan binatang air lainnya akan melekat dengan kuat pada karang itu. Di karang itulah mereka berlindung agar tidak hanyut. Ombak selalu datang membawa air laut yang baru. Dari sanalah kerang dan binatang kecil itu mendapatkan makanan. Jika kalian melihat sepotong karang, kalian tidak akan mengenali binatang kecil yang menempel padanya. Hal itu karena binatang itu bisa menyamar dengan baik sehingga bentuknya tidak bisa dibedakan dengan karang tempat mereka menempel. Jika ada ganggang air tumbuh di atas batu, batu itu berarti lunak. Batu yang lain berduri dan dilapisi pecahan kulit kerang yang sangat tajam
B) Mengapa Laut Berombak?
Jika kalian meniup air kuat-kuat dalam baskom, permukaan air itu akan bergerak, bahkan bisa sampai tumpah. Hal itu terjadi di laut. Angin yang bertiup mengakibatkan terjadinya ombak. Badai di lepas pantai yang jauh dan terbuka menggerakkan air dalam jumlah yang sangat besar. Itulah yang disebut gelombang laut. Gelombang dari tengah laut bisa sampai membentur pantai. Gelombang laut ini sangat berbahaya bagi para perenang di pantai. Mereka bisa terseret ke tengah laut. Binantang di bawah laut pun menghindari gelombang laut seperti itu. Mereka menyelam lebih dalam lagi. Di kedalaman tidak terasa gerakan air yang ada di permukaan.

Why Denomination reefs in water, barbed-thorns? Why choppy seas?
(source: Rosda Group.1994. Encyclopedia of Marine and Ocean.Jakarta: PT Rosda Jayaputra.)
A) Why Denomination Reefs in Water?
If, split rock continuously hit the water, various kinds of shellfish andother aquatic animals will be attached firmly to the rock. On the reefthat they hide so as not to drift. Waves always come with newseawater. From there, clams and small animals that get food. If yousee a piece of coral, you will not recognize the small animalattached to it. That's because the animal can be disguised so well that looks indistinguishable from the reef where they were attached.If there is water algae growing on the stone, it means the software.Another stone fences and broken coated shells are very sharp
B) Why Wavy Sea?
If you blow hard water in the basin, the water will move, even to thespill. It happened at sea. Winds blowing resulted in waves. Storm off the coast of the remote and open moving water in a very large number. That's called the ocean waves. The waves of the sea could be up against the shore. The ocean waves are very dangerous for swimmers at the beach. They can be dragged out to sea. The animals under the sea to avoid any waves like that. They divedeeper. In depth does not feel the movement of water on the surface.
