Zvakazorodza muAtlantic Ocean paburiro. The chikuru zviri kuedza kuAtlantic Ocean uriri

Ngationgororei zvakadzama zvakazorodza muAtlantic Ocean paburiro. dingindira iri mune mamwe mabhuku akawanda iri kukurukurwa zvechipameso. Naizvozvo akakodzera nokuti vazhinji ndiyo mubvunzo: "? Kupi ini angawana rondedzero Atlantic Ocean" Dzimwe nguva zvinoda kunyatsodzidza chidzidzo ichi. Munyaya ino isu vakaedza napo pachena nyaya yacho.

Sezvo tsanangura pasi kwakaita nzvimbo yacho kuti Atlantic Ocean, tinoona kuti Mid-Atlantic Ridge - yayo huru orographic maatomu akafanana. Maererano nzvimbo ndiye chete zvishoma zvishoma pane seafloor (24.6% uye 37,6% azvaitwa). All yomugungwa muhomba runoparadzanisa migove miviri. Vari kuda vakaenzana kukura. General ruzivo pamusoro Atlantic Ocean, uyewo vakawanda ruzivo jogirafi kuchaita kuti tinzwisise zviri nani zviri mungozi munyaya ino. Kuti kumiririra nani nzvimbo penyanza yatiri vanofarira, isu zano kuti vanyatsoziva pamwe kadhi.

Kumavirira muMedhia akapiwa muhomba

Newfoundland muhomba iri kumadokero epakati yomugungwa akatevedzana. Plateau Rio Grande, nokumutsa Ceará, Ridge Barracuda uye Bermuda ebani, uyewo maberere of Mid-Atlantic Ridge uye Continental kumahombekombe pasi mvura, vagovane kumadokero hafu penyanza pauriri kuArgentina, Brazil, Guiana (the Guyana), North America, Newfoundland uye Labrador Basin . Norwegian-Zimbabwe Basin uye Sea Baffin zvinowanzonzi sechikamu yakasiyana mumakungwa - kweArctic.

Labrador uye Newfoundland Basin

Tinoenda nyaya iri chivezwa muAtlantic Ocean paburiro. Rondedzera muchidimbu nembiya mbiri - Newfoundland uye Labrador (kufadza kudzama vekupedzisira - 5160 mamita). Ivo, Chokwadi, vanoumba chete chimwe. Vazhinji vavo inoremekedzwa flat abyssal mubani. In dzesub Meridian nhungamiro nayo chinoyambuka abyssal mumupata Hazen. Newfoundland Basin kudzivirirwa kubva kumaodzanyemba akatevedzana chete zita. Ndiye ari kuunganidza hofori chimiro, riri chokuita kufamba yakadzika-dzomugungwa sedimentary zvinhu sezvinoratidzwa siyana zvizivikanwe nemichina acoustic kudzidza.

American nembiya North, Guiana uye Ceará

North American Basin - iyi ndiyo imwe nembiya kupfuura kuti ungaona zvakazorodza muAtlantic Ocean paburiro. A tsananguro pfupi zvayo acharamba nyaya yedu. Mukuru kudzika bheseni ndiyo 7110 mamita. Bermuda rwenze iri rinenge pakati nechekuchamhembe. It zvakare pachena kuputika massif Corner (zvimwe unonzi chisina kutsetseka anosimudza) neGomo Kelvin. Wavy abyssal bani rinoenderera Bermuda rwenze nechokumaodzanyemba. On arikunze pakati bheseni vari sandara abyssal mumapani Nares, Hatteras uye Catfish. North America Basin bordered neZasi-kumadokero kubva Blake-Bahama Ridge, uyewo kwokunze Antilles mugodhi. Last kunosvika achitevedza Puerto Rico mugoronga. Anoparadzanisa, pamwe blocky muhomba Barracuda, riri pamusoro wayo rakazotevera, kuti Guiana bheseni kubva North America. Inflow terrigene sedimentary zvinhu anopa anenge nokudenga kusimudzira sandara abyssal mapani inonzi bani Demerara mukati mhango Guiana. Guiana Basin ane kunonyanyisa kudzika 5109 metres kuchamhembe-yokumadokero chikamu, iyo inozivikanwa kunyanya nemumakomo. Small kadikidiki vachisimudza Ceará rakaoma nokuda pemvura anoputika, zviri akaparadzaniswa wamashekeri Ceará. Mukuru udzamu ndiyo 4700 mamita wokupedzisira. Pasi bheseni inogarwa rakati sandara mubani chete zita. Zvinofanira kucherechedzwa mumwe 2 mumipata abyssal. Uyu Wild, izvo incision udzamu rinosvika mamita 250 (richibatanidza Guiana uye North America nembiya) uye Pernambuco (rinobatanidza Brazilian uye Guiana Basin).

Brazilian Basin

Kudeuka bheseni kumadokero chikamu penyanza - Brazil. Pano, zvakazorodza muAtlantic Ocean uriri vainyanya nemumakomo. Pabani Pernambuco, duku kunharaunda bheseni, zviri Wavy. Yepasi pemvura anoputika iri muzvizhinji mu wokushambidzira wokuBrazil. Vamwe simukai pamusoro pegungwa, pova chitsuwa kuputika (Martin iwe, Trinidad, Fernando of Noronha).
