Importance of Earth Hydrosphere

         Does hydrosphere important to us? What is hydrosphere all about? if there no hydrosphere what would be the possible things that may happened to us? This is some of the question that bother my mind.
           Hydrosphere have an important role in this planet Earth, it help to manipulate the heat comes from the sun so that we cannot suffer an intense heat. We all know that hydrosphere consist of heavenly body of water such us oceans, lakes, rivers, streams, underground and frozen in glaciers. Hydrosphere also called as "water sphere". Ocean current also help to disperse heat. Water take a long time to heat up and also long time to cool down, its help to regulate temperature here on Earth so that they stay within a range that is acceptable for life to exist. Our planet also have water on surface, which is very unique. Only the have this kind of characteristic that why Earth also called "blue Planet" because of the water surrounded it. It made of fresh water like rivers and streams. The use of hydrosphere  to generally lost the heat to the space. Oceans serve to main purpose in the climate system. First, it is the large reservoir  of chemical that can contribute  to the greenhouse effect of the atmosphere, and help to absorb the solar radiation which hit the surface. This reservoir change very slowly limiting  how past the climate can change. Second, it work with atmosphere to redistribute the energy received from the sun such that the heat and lot or many energy is received from the sun transfer to the poles.

                  Hydrosphere not only can hep the planet or protect the planet from the heat coming from the sun, but it help also to the people to survive and exist their life to the better one. Water is so important in mans life, its the major needs of man. We cant live without water. Human use water in many ways like drinking and washing. Drinking water is obviously very important. This is the some of importance of hydrosphere to us.
                                 
                                       In our high school day we topic about the three primary state of matter on Earth it is the solid, liquid and gas.The distance of Earth from the Sun, by fortunate coincidence, is such that the amount of energy arriving at the surface of most of the planet is sufficient to elevate the ambient temperature to levels above the freezing point of water, yet insufficient to cause all of the water to evaporate into the gaseous state. The capacity of water to store large quantities of heat energy heavily influences the nature of the global climate. The presence of large bodies of liquid water and the atmosphere restrict the range of temperature fluctuations on Earth. These conditions have allowed the existence of the fourth component of Earth's system, the biosphere. Hydrosphere main purpose is to protect the Earth by the help of the water consist it. If there no hydrosphere we cant survive because we can directly received the intense heat coming from the sun , and that is very dangerous to us.

The hydrosphere has provide water for our crops. Crops have provided all our nutrient needs since life exist. The hydrosphere also provides us with water to hydrate our body. Without the hydrosphere we would not be living because it is simply how we survive on this earth.

Advantage and disadvantage of Science and Technology

                In our modern world Science and Technology are important,beside there are many people can't live without such gadgets or invention.But we all know that even its important to us but still there are many disadvantage in us,because of this technology we became dependent and also over using this technology can cause a cancer because of the radiation.Even in our environment it may cause damage.All good thing for us have also their side effect.Now we depend machine to do all our household chores and even our schools assignment and activities.Technology is important in order us to communicate  our love ones outside the country.
              Science is the key by which man go anywhere or travel everywhere at any time in the space and even in land or in the air.Its because of the great invention of our intelligent scientist.It is true that the most striking features of the present century is the process of science.We are lucky that there are many great invention have been born.Computer is one of the useful invention,but there are many teenagers addicted computers.Chatting,playing dota and many more is their priority instead of studying their lesson to be a successful one.We can see that this machine can influence in every aspect of their everyday life both for better and for worst.The advantage of science and technology are:
         1. Less work for human
                           -we don't need to work and work in order us to finish our job faster.We can use machine to help us in doing our work don't need our effort.
          2. Make life more enjoyable
                          -gadgets help people to forget their problems even in a few  minutes/hour.Modern technology now can help people to be more happier that  before,make life people enjoy their life to the fullest.
           3.Medicine easier to synthesize
                         -help the doctors to combine all ingredients needed effective medicine.Help in analyzing the right procedure in making medicine.
                4.Faster to do some jobs
                                   -machine help you to finish your job on time,and it can minimize your time in doing such job or task.You must depend the capability of that machine to do your work without any physical effort.

The disadvantage of Science and Technology

                                         Technology make people to be dependent,can't work without the the help of that machine.People become lazy,can't do in their own.They can't live without gadgets.Most people say that they can't live without computers,maybe that's true because even any school activities almost all student need computer and internet in making their reports and many more.But not that point that cant live without any gadgets,maybe others.Invention have also there disadvantage to us and even in our environment/society.Disadvantage follows:

           1.Environment is polluted and damage
                            -because of the technology and inventions that scientist invent in order  us to finish all our job on time and faster but still there are an effect that can  damage our mother Earth,they made our environment  more polluted because of
 the smoke that the vehicle produce and factories.
         



                                                                  
                                                                                                       2.More weapon created
              -easily in doing any kind of weapon with no license.Making weapon in an illegal way,they can easily make any  kind of weapon in just a minute in the help of such technology.

 3.People become lazy and don't work
                      -they depend on the technology,they usually use any invention to help or do their work.They become so dependent of all the gadgets that invented instead in using firewood in cooking but now we use electricity.
         4.Climate change
                         -the technology that being invented is the one reason for the climate change.Example is the refrigerator,it produce CFC that can make the ozone layer destruct or break the ozone layer that may result to climate changes.
