位于环流路径上的陆块会得到大量的垃圾。

This caused huge rifts between these land masses and ultimately created the continents we see today.

这导致这些陆块间出现巨大裂缝，并且最终形成了我们今天看到的各个大陆。

Through the forces of plate tectonics, the land masses shifted and sea level rose flooding large areas.

通过板块构造的力量，陆块移位，海平面上升淹没了大片区域。

The island is located in the Indian Ocean roughly 300 miles east of Africa over the Mozambique Channel and is otherwise isolated from significant land masses.

马达加斯加岛位于印度洋，离非洲以东大约300英里，间隔莫桑比克海峡，远离大陆地板块。
