Genel Dünya Hakkında Bilinmeyenler 02 Mart 2019 00:16
Üzerinde yaşadığımız gezegenden ne kadar haberimiz var? Dünya, nasıl bir gezegen ve dünyada neler oluyor? İşte bazı cevaplar.
Dünya’nın çekirdek kısmı 5500 santigrat derece sıcaklıktadır. Bu sıcaklık, Güneş’in yüzey sıcaklığına hemen hemen eşittir.
Dünya’nın en uzaktan çekilmiş fotoğrafı, yaklaşık 6 milyar kilometre öteden çekilmiştir ve Soluk Mavi Nokta olarak bilinir.
Dünya üzerinde keşfedilmiş en dayanıklı canlı olan Tardigrad, vakumlu uzay ortamında 10 gün hayatta kalabilme özelliğine sahiptir.
Uluslararası Uzay İstasyonu yapımına 150 milyar dolar harcanmış Dünya’da üretilen en pahalı yapıdır.
Dünya, bir bowling topundan bile daha pürüzsüz bir yapıdadır. Bowling topunun üzerindeki, hissedilemeyen pürüzlerin aksine, en yüksek dağ ile en derin okyanus bile Dünya yüzeyinin kalınlığının sadece 5 binde 1’ini oluşturur.
Antarktika’daki toplam buz miktarı, Atlas Okyanusu’ndaki su miktarına eşittir.
Okyanuslarda ortalama 1.000.000 adet tür yaşadığı düşünülmektedir. Üstelik tüm okyanus türlerinin sadece %33’ünün keşfedildiği tahmin ediliyor.
Dünya üzerindeki tüm volkanik aktivitelerin, %90’ı okyanus tabanlarında gerçekleşmektedir.
Dünya, Güneş Sistemi içerisinde levha tektoniğine sahip tek gezegendir. Ancak eğer levha hareketi olmasaydı, karbon tüketilip yenilenemezdi ve Dünya, tıpkı Venüs gibi aşırı ısınırdı.
Dünya’nın en büyük kristalleri, 55 ton ağırlığındadır. Bu kristaller, Meksika’nın altındaki Naica gümüş madenlerindedir.
