Apa Gunung Es itu? Apakah laut juga bisa membeku?
(sumber: Rosda Group.1994. Ensiklopedi Laut dan Samudera. Jakarta: PT Rosda Jayaputra.)
A) Apa Gunung Es itu?
Di wilayah kutub, gletser yang bagaikan sungai besar tertutup es, meluncur sampai ke laut. Gletser itu berupa balok es raksasa yang kadang-kadang pecah atau patah. Hal itu merupakan kelahiran gunung es. Orang menyebutnya juga dengan gunung es “beranak”. Pada saat badai atau angin bertiup, balok e situ meluncur ke tengah laut. Lama kelamaan bagian atas balok es itu mencair oleh panas matahari. Beberapa bagian ujungnya terlepas oleh perairan panas. Di bawah permukaan air bagiannya yang lebih besar masih tetap utuh, seperti es batu dalam gelas berair. Oleh karena itu, gunung es sangat berbahaya bagi kapal yang sedang berlayar. Hal itu disebabkan hanya per sepuluh bagian gunung e situ saja yang tampak di atas permukaan air.
B) Apakah Laut juga bisa membeku?
Air laut tidak membeku secepat air tawar karena air laut mengandung garam. Garam bisa digunakan untuk mencairkan es. Di daerah kutub yang sangat dingin, lautnya membeku. Lapisan itu terdiri atas bongkahan es yang bergerak bersama atau saling menabrak. Anjing laut yang terperangkap dibawahnya membuat lubang untuk bernapas. Lubang itu tambak seperti cerobong asap. Jika lapisan e situ mencair dan pecah oleh sinar matahari, bermacam binatang, seperti penguin dan beruang es, mulai mengungsi. Mereka mengikuti bongkahan es yang hanyut.

What's Iceberg? Is the sea can also be frozen?
(source: Rosda Group.1994. Encyclopedia of Marine and Ocean.Jakarta: PT Rosda Jayaputra.)
A) What is the iceberg that?
In the polar regions, glaciers covered like a great river of ice, sliddown to the sea. Glaciers in the form of a giant block of ice that sometimes cracked or broken. It was the birth of an iceberg. Peoplealso call it the iceberg "childless". At the time of the storm or the wind blows, there e beam sliding into the sea. Eventually the top of the block of ice was melted by the heat of the sun. Some of the edges removed by hot water. Below the water surface the largerpart still intact, like an ice cube in a glass of water. Therefore, theiceberg is very dangerous for a ship sailing. That is because themountain is only a ten-part e there are visible above the water.
B) Is the sea can also be frozen?
Sea water does not freeze as quickly as fresh water because sea water contains salt. Salt can be used to melt ice. In the polar regionsare very cold, the sea froze. Layer is composed of chunks of ice that move together or hit each other. Seals were trapped underneath a hole to breathe. The hole pond like a chimney. If there e coatingmelts and broken by sunlight, a variety of animals, such as penguinsand polar bear, began to flee. They follow the drifting icebergs.
