Below shows how the natural water cycle is formed.

Water \(\rightarrow\) Water vapour \(\rightarrow\) Clouds \(\rightarrow\) Rain

The heat from the Sun causes water to evaporate from oceans, lakes and streams.

Evaporation occurs when liquid water on Earth’s surface turns into water vapour in our atmosphere.

Water vapour rises up through Earth’s atmosphere.

As the water vapour rises higher and higher, the cool air of the atmosphere causes the water vapour to form the clouds.

When a cloud becomes full of liquid water, it falls from the sky as rain.

Rainwater flows back into rivers, lake and sea and the process starts all over again

Di bawah menunjukkan bagaimana kitaran air semula jadi terbentuk.

Air \(\rightarrow\) Wap air \(\rightarrow\) Awan \(\rightarrow\) Hujan

Panas daripada Matahari menyebabkan air disejat dari lautan, tasik dan sungai.

Penyejatan berlaku apabila air di permukaan Bumi berubah menjadi wap air di atmosfera kita.

Wap air naik melalui atmosfera Bumi.

Semasa wap air naik lebih tinggi dan lebih tinggi, udara atmosfera yang sejuk menyebabkan wap air membentuk awan.

Apabila awan menjadi penuh dengan air, awan akan turun dari langit sebagai hujan.

Air hujan mengalir kembali ke sungai, tasik dan laut dan prosesnya bermula berulang kali.
