WATER CYCLE
Background:
The earth is referred to as the blue planet – ¾ or 75% of the earth is covered with water.
Water is also known as the universal solvent.
Water can be in liquid form, as in oceans, seas, rivers, lakes, and other bodies of water. It can also be in a solid form
such as in glaciers and ice caps. Water can also be presented in water vapor, the invisible gas in the air that you take in as
you inhale.
The water on Earth is always recycled. It is used, returned to the environment and used over and over again.
Water Cycle or Hydrological Cycle is the continuous movement of water rising from the earth to sky and back to earth.
STEPS OF THE WATER CYCLE

1. Evaporation is when the sun heats up water in rivers or lakes or the ocean and turns it into vapor or steam. The water
vapor or steam leaves the river, lake or ocean and goes into the air.
People perspire (sweat) and plants transpire. Transpiration is the process by which
plants lose water out of their leaves. Transpiration gives evaporation a bit of a hand in
getting the water vapor back up into the air.
2. Condensation. Water vapor in the air gets cold and changes back into liquid, forming clouds.
Dew is formed when water vapor comes into contact with cold
surfaces such as leaves and glass
3. Precipitation occurs when so much water has condensed that the air cannot hold it anymore. The
clouds get heavy and water falls back to the earth in the form of rain, hail, sleet or snow.
Some droplets fall on land and are absorbed by the ground, while others fall into bodies of
water and this process is called collection. The water cycle then starts all over again.

IMPORTANCE OF WATER CYCLE

Water cycle is an extremely important process because it enables the availability of water for all living organisms and
regulates weather patterns on our planet. If water didn't naturally recycle itself, we would run out of clean water, which is
essential to life. When water falls to the Earth, the water seeps into the soil because of the force of gravity. Water cycle is
a process that is constantly recycling the Earth's supply of water. This is important because humans, animals and plants all
need water to survive and grow. Water Cycle sustain life and create the ecosystems around us. Some
organisms are very sensitive to changes in the water cycle. A prolonged drought can destroy a population of plants or a
certain animal which may require an amount of water in the soil in order to avoid dehydration.
Learning Competency: Identify the importance of the water cycle. Code: S4ES-IV
Activity 1: Arrange the jumbled words below to form the processes in the Water
Cycle. Using the descriptive phrases as your clue.
____________________1. (R A T S P I N T A R I O N) - is the process by which plants release water from

their leaves.
____________________2. (T A T P O I N R E C I P I) – is the process by which the condensed water vapor
falls back on the Earth’s surface in the forms of rain, hail, snow, and sleet.
____________________3. (A S O N T E N D I C O N) - is the process of changing water vapor (gas) into
liquid water.
____________________4. (T I N O P O V A E R A) - is the process of changing liquid water into gas (water
vapor).
____________________5. (N S U) - causes the water to become warm and evaporate
