leading edge of the plate

The ridge is formed primarily from marine sediments scraped off the top of the Australia plate and piled up on top of the leading edge of the Sunda Plate.

洋脊的形成主要是由于从澳大利亚板块顶端刮落的海洋沉积物，在巽他板块的前端表面堆积起来了；

As the leading edge of one plate is consumed beneath the other, some of the magma finds its way up between cracks and crevices in the continental crust.

随着一个板块的前边缘被淹没在另一个之下，有些岩浆会顺着大陆地壳中的裂缝和缝隙向上涌出。

As these volcanoes grow, they rise above the ocean surface to form lines of islands along the leading edge of the overriding plate.

随着这些火山的生长，它们上升到海面以上会沿着仰冲板块的前缘形成岛链。
