Đề bài
The diagram below shows the water cycle, which is the continuous movement of water on, above, and below the surface of the Earth. Summarize the information by selecting and reporting the main features, and make comparisons where relevant.
Sample Answer (Band 9)
The diagram illustrates the natural process of the water cycle, demonstrating how water moves through various stages from the ocean to the atmosphere and back to the land.
The cycle begins when solar energy heats the ocean surface, causing evaporation. Water vapour rises into the atmosphere, where it cools and condenses to form clouds. As the clouds become heavier, precipitation occurs in the form of rain or snow, falling onto both land and water bodies.
On land, some precipitation infiltrates the ground, forming groundwater, while the rest flows as surface runoff into rivers and streams, eventually returning to the ocean. Additionally, plants absorb water from the soil through their roots and release it back into the atmosphere via transpiration, contributing to the formation of clouds.
Overall, the water cycle is a continuous and balanced system where water is recycled through evaporation, condensation, and precipitation, ensuring a constant supply of fresh water on Earth.
