The document discusses water resources and the hydrological cycle. It begins by defining the hydrological cycle and discussing its major processes. It then explains that water exists in three forms - solid, liquid, and gas - due to climatic variations. Water is essential for life but must be preserved and used carefully. The document further analyzes the hydrological cycle and how water circulates between the oceans, atmosphere, and land in vapor, liquid, and solid forms. It also notes that while water is abundant globally, freshwater availability does not always meet demand.

WHAT IS THE HYDROLOGICAL CYCLE
DEFINING WHAT THE H.C IS?
DISCUSSING THE MAJOR PROCESSES OF THE H.C
A FURTHER ANALYSIS OF THE WATER CYCLE
A PRE BRIEF ANALYSIS OF THE DIFFERENT STATES OF WATER
A PRE BRIEF OF THE WATER CYCLE CONTINUED
DIFFERENT FORMS OF WATER IN THE WORLD Water is present almost everywhere. If the earths map is observed keenly, it is found that most of the area is blue in colour, indicating the presence of water. About 71% of the earths surface is covered with water. Water is present in oceans, seas, lakes, rivers, ice caps, as groundwater and in the atmosphere. However take note that Water exists in different forms. On the earths surface, there are three different forms of water namely solid, liquid and gaseous. Water exists in different forms due to the variations in climatic conditions. Water is a very important resource as it is used for drinking, cleaning, cooking etc. It should be preserved and carefully used as it is required for the survival of life on earth.

DIFFERENT FORMS OF WATER IN THE WORLD, CONTINUED: Water is being continuously used and water conservation is the major concern in the present scenario. The water cycle has helped in maintaining water on the surface of the earth for millions of years. The water circulated in water cycle takes three different forms solid, liquid and gaseous. The solid form of water ice, is found at the poles of the earth, the snow covered mountains and the glaciers. The liquid form is present in the rivers, lakes, seas, and oceans. The gaseous form of water, water vapour is present all around us (Even at this moment, the air we breath contains water vapour.
DIFFERENT FORMS OF WATER IN THE WORLD, CONTINUED: Water present in the oceans and seas evaporate due to the suns heat and get converted into water vapor. Ice caps and snow can directly sublimate into water vapor. The atmosphere has lower temperatures in some parts of the world which causes water vapor to condense into tiny droplets. These tiny droplets are heavier than air and therefore may fall if not supported by any uplift. A huge concentration of these tiny droplets results in the formation of visible clouds. The cloud particles collide with dust particles and precipitation occurs.
DIFFERENT FORMS OF WATER IN THE WORLD, CONTINUED: Precipitation occurs in the form of rain or snow. Rainwater falls on earth and flows to the rivers and lakes and some of the rainwater is absorbed by the earths surface. The groundwater gets replenished by rains. This cycle continues in order to maintain the water balance on the surface of the earth.
