It's a crack in the Earth's surface that runs as far as the eye can see.
這是地球表面的一道裂縫 一眼望不到頭
But even this is is just a small part of something far bigger.
然而這僅僅是整體中一個很小的部分
To the left is a gigantic slab of the Earth's crust
這是地殼上一個巨大板塊的邊界
which runs unbroken for over 4,000 miles
完好無損的延綿了7千公里
from here,under the Atlantic,
就從這里開始 穿過大西洋
across the USA,all the way to California.
橫跨美國 一直到達加利福尼亞
It's what's known as the North America Plate.
也就是北美大陸板塊
The earth's surface is broken up into seven major chunks called plates.
地殼表面分成七大塊，稱為板塊
They are so enormous, that they can carry an entire continent
他們是如此的廣袤 他們連同大陸板塊
and extend far under the sea.
一直延伸到海底
Strip away the Atlantic and the long boundary between two of plates
剝離掉大西洋你會看到兩個板塊間
that runs along the ocean floor,is exposed,
長長的分界線 沿著海底
until it rises above the waves,
一直延伸到海岸上
and cuts through Iceland,
穿過冰島
to eventually join up with the rock face at Thingvellir.
最終在古議會遺址處和巖層匯合
These sheer rock faces were once joined together,
這些巖層曾經是連在一起的
but driven by the churning force of molten rock beneath them,
但受到熔巖下方龐大地質力量的作用
the land was split apart.
陸地被分裂開
