Water Cycle

     Water is very important for human, animal, and plant. Water moves from one place to another. Do you know how water cycle works? Solar energy evaporates exposed water from seas, lakes, rivers and wet soil, the majority of this evaporation takes place over the seas. Water is also released into the atmosphere by the plants through photosynthesis. During this process, known as evapotranspiration, water vapour rises into the atmosphere.

     Clouds are formed when air becomes saturated with water vapour. The two major types of cloud formation are stratified or layered grey clouds called surutus and following white or dark grey cloud called cumulus clouds.
Precipitation as rain or hail ensures the heated water reruns to earth’s surface in a fresh form. Some of this rain, however, falls into the seas and is not accessible to humans. When rain falls, it either washes down hill slopes or seeps underground, when snow and hail melt, this water may also shrink into the ground.

     Rain fall also replenishes river water supplies so does underground water. Snow fall may consolidate into glaciers and ice sheet which, when they melt, release their water into the ground, into streams or into the seas.

     That is how water cycles from one place to another, from one form to other forms. This kind of text explain how a thing processes into the fixed form. 

Why Do Seasons Change?

     Seasons come to us regularly. We have probably noticed that it gets warmer in summer or dry season while it get colder in the winter or wet season. However do we know how these seasons change?

Seasons happen and change every year. This happens because the earth tilts back and forth as it goes around the sun. During the summer, the earth tilts toward the sun. It makes half of the earth hotter. this condition is what we call summer. During the other half of the year, the earth tilts away from the sun. As a result, it makes that half of the earth cooler. This cool condition is then what we call winter.

     The different parts of the world have the same season at different times. In the northern half of the world , winter happens during the months of December, January and February. The regions are such North America and Europe. In the other hand, the southern half of the world have winter during the months of June, July and August.The regions are like South America and Australia. How does this difference happen? The same season happens at different times because the top and bottom halves of the earth tilt away from the sun at different times.
