Ada apa kat dasar laut paling dalam?
Question:"How deep is the deepest sea?"
Jonas from Amsterdam, Holland
Answer:
The deepest known spot on the planet is called the Challenger Deep, found at the bottom of the Mariana Trench east of the Philippine Islands in the Pacific Ocean. Sounding of the depths in the Mariana Trench measure 11,033 meters (36,198 feet). This is approximately 2180 meters (7152 feet) deeper than the tallest mountain on the Earth抯 surface, Mount Everest (8,846 meters: 29,022 feet)! (Source: NOAA)
makhluk apa yang wujud kat kedalaman 11033 meters tu agaknya?aku teringin nak tengok rupanya,dia makan apa,tak bosan ke dia duduk dalam2 tu..tanampak cahaya matahari,ada komuniti ke tak,kalau dia jumpa ikan yg duduk kat bahagian atas lagi mesti garang macam kucing tak pernah jumpa orang,kikiki.;P
agaknya2 kalau sebiji batu atau metal padu jatuh ke dalam laut,ada chance tak sampai bawah sana.atau,kalau pegi bawah sana,ada kemungkinan tak jumpa barang2 buatan manusia~ 11,033 meter ! tentu tekanan dier teramat tinggi..kalo ader besi jatuh ke sana,mungkin besi itu dikoyak-rabakan oleh tekanan air disana :funk: ...tak tahu ader ke kehidupan kat sana,tak setahu tak ader kapal selam yang withstand tekanan air nie.. :lol: tak pernah terpikir pun ni sume...
takut pun ade gak ni... The deepest known fish in the oceans are brotulids Abyssobrotula found in trenches at over 8000 m and thus in the Hadal or Hadopelagic zone. The record appears to be an Abyssobrotula galatheae at 8372m in the Puerto Rico trench .

kalau bola sepak jatuh sedalam tu,bola tu akan mengecil sekecil guli kerana tekanan yg sgt kuat. aku rasa x der makhluk yg idup kat dalamair yg sedalam tu..
coz tekanan yang gegila,meletup kot ikan tu Originally posted by jimbait at 19-2-2007 22:20

tentu ikan tersebut ader ciri-ciri penyesuain..sbb byk hidupan boleh hidup kat tempat yg extreme..;P

Dalam lautan dalam ada banyak hidupan pelik-pelik.Seram betul aku tengok ikan-ikan lautan dalam tu....:funk: mesti ade makhluk asing tinggal kat sana Jurang Mariana
Kedalaman: 11033 meters
Kedudukan: North Pacific Ocean, to the east and south of the Mariana Islands at 11 kalau nak kira tekanan, pakai equation rho.g.h
rho air laut ~ 1000 kg/m^3
g = 9.81 m/s^2
h = 11033 m
P = 1000 x 9.81 x 11033 = 108233730 Pa = 1082 barg
utk perbandingan, tekanan dlm tayar kereta = 1 barg Dekat lautan dalam aku pernah terbaca mengenai ikan Tanglung.Ada sapa-sapa boleh letak gambar dia tak?Aku dah lupa rupa ikan tu.:)

Ehhh...tambah satu lagi...:)Tekanan,P=Tekanan air + Tekanan atmosfera
=ketumpatan air X tarikan graviti Bumi X jarak antara permukaan dengan titik sasaran + Tekanan atmos.

kalau sapa2 penah tengok spongebob, ada satu siri yg dia terjatuh dlm abyss.ada satu karektor ikan tanglung.
tanglung tu salah satu fungsi dia nak memikat mangsa. Originally posted by orang_awam at 21-2-2007 01:10

ni mcm pic kat atas tu..Idiacanthus antrostomus
fact:
The males are small, about three inches (8 cm) in length, and brownish in color. They have no teeth, no chin barbel and no stomach. Unable to eat, the male lives only long enough to mate.

The fish of the deep sea are among the most elusive and unusual looking creatures on Earth. Since many of these fish live in regions where there is no natural illumination, they cannot rely solely on their eyesight for locating prey and mates and avoiding predators; deep sea fish have evolved appropriately to the extreme sub-photic region in which they live. Many deep sea fish are bioluminescent, with extremely large eyes adapted to the dark, and they can have long feelers to help them locate prey or attract mates in the pitch dark of the deep ocean. The deep sea angler fish in particular has a long fishing-rod-like adaptation protruding from its face, on the end of which is a bioluminescent piece of skin that wriggles like a worm to lure its prey. The lifecycle of deep sea fish can be either permanently deeply submerged or they are sometimes born in shallower water and sink on becoming adults.
Due to the poor level of photosynthetic light reaching deep sea environments, most fish need to rely on organic matter sinking from higher levels, or, in rare cases, hydrothermal vents. This makes the deep sea much poorer in productivity than shallower regions, with most deep sea fish noticeably smaller and have larger mouths and guts than those known to us. It has also been found that the deeper a fish lives, the more jelly-like its flesh and the more minimal its bone structure. This makes them slower and less agile than surface fish.
