After new oceanic crust forms, the lithosphere cools and thickens as it moves away from the ocean ridge. An alternative to an active mantle thermal anomaly is greater stretching of the mantle lithosphere than the crust

在新的洋殼形成後，岩石圈隨著遠離洋脊的移動而冷卻和變厚。活動的地幔熱異常的替代方法是地幔岩石圈的拉伸大於地殼

Besides, both north-east and south-west monsoons have a higher level of rainfall which may discourage farmers from applying more fertilisers.

此外，東北季風和西南季風的降雨量都較高，這可能會阻礙農民施用更多肥料。

The occurrence of major pulses of oceanic water has proved unpredictable, being non-existent during the 1980s. The two eastern forks of Long Island jut into oceanic waters, creating a mixing zone for currents and coastal and offshore migratory species.

事實證明，海洋水的主要脈衝的發生是不可預測的，在 1980 年代不存在。長島的兩個東部分叉伸入海洋水域，為洋流和沿海和近海遷徙物種創造了一個混合區。
