Why do the oceans play such a large part in the water cycle?

Oceans are the source of water for the water cycle.

The oceans play a large part in the water cycle primarily because they cover a vast majority of Earth's surface, which facilitates a significant amount of water evaporation. Oceans contribute to about 90% of the evaporated water in the hydrologic cycle, which is essential for the biodiversity and the climate regulation of our planet. Additionally, the oceans function as a crucial reservoir, holding approximately 95% of the world's water, thereby playing a vital role in shaping the weather and the various ecosystems on Earth.
Over time, oceans have collected water which has been cycling as it evaporates and returns as precipitation. The cycling of water is significant not just for ecosystem dynamics but also for maintaining climate balance. Impacts of human activities such as pollution and overfishing are detrimental to the oceans, threatening this important natural cycle and the overall health of our environment.

Oceans are essential to the water cycle, acting as the main source of evaporation and storing the majority of Earth's water. They help regulate the climate and support diverse ecosystems. The ocean's vastness allows for significant water exchange between land and air, crucial for sustaining life on Earth.
