Water is Precious
Did you know that water is a vital ingredient for life on earth, and that we share it with every other living thing on the planet? As humans, we borrow water from nature to use in our homes, schools, and workplaces, but we always have to send it back to the environment, so that it can be used by other living creatures as well.
Let’s talk about The Water Cycle.
The Water Cycle
Water is precious
Over 70% of planet Earth’s surface is covered in water, but did you know that less than 1% of it is actually all we have to share, not only with each other, but with all living things?’
Water is so important to maintain life, that it’s one of the key markers scientists use in searching the universe for life, or planets where life could at least be possible.
The amount of water we have on Earth hasn’t really changed much over time. The amount we need to use as humans keeps growing. This means we need to be careful about how we use water; and be sure that we use is returned to the environment in good condition.
70% of the earth’s surface is covered in water
Of this, only 3% is fresh water
But only 1% is accessible for human consumption
Precipitation
Water vapour can collect as clouds in the atmosphere. When conditions are right, clouds release their water to fall back to Earth.
Find outEvaporation
Evaporation is the process of liquid water turning to a gas, or water vapour. As a gas, water rises from Earth’s surface into the sky.
Find outCondensation
As the water vapour rises, it reaches cooler air and forms back into tiny droplets of water. This is what we see as clouds.
