Detailed explanation-1: -Water eventually returns to the ocean as precipitation that falls directly into the sea and as precipitation that falls on land and flows to the ocean through rivers.

Detailed explanation-2: -The water cycle is an important phenomenon of returning water back to the oceans. The water from the oceans evaporates. This evaporated water condenses and falls back as rain. The water that falls on land flows into the rivers and ultimately falls into the oceans.

Detailed explanation-3: -When molecules of water vapor return to liquid or solid form, they create cloud droplets that can fall back to Earth as rain or snow-a process called condensation. Most precipitation lands in the oceans.

Detailed explanation-4: -Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow. Water in different phases moves through the atmosphere (transportation).
