WHAT TWO ELEMENTS MAKE UP WATER

HYDROGEN AND OXYGEN ARE WHAT TWO ELEMENTS MAKE UP WATER

INTRODUCTION:

From outer space, earth appears blue. The reason behind this is the presence of water in the sea and ocean. Water is present in 71 % of the earth. About 98% of water is present in sea and ocean, that means maximum part of water is salty.  What two elements make up water are hydrogen and oxygen ,  out of which saline water  is not fit for human consumption.  Even plants and other living organisms cannot consume it. Very small amount of fresh water is available in this planet.

DIFFERENT FORMS OF WATER IN WHAT TWO ELEMENTS MAKE UP WATER

There are three forms of water like :

  • SOLID FORM : In the earth, we can see solid form of water as ICE or SNOW. We can notice it as ice caps, glaciers, or snow covered mountain  in polar region or high altitude of land in what two elements make up water.
  • LIQUID FORM: We find this form everywhere as rivers, ponds, lakes, spring, well (ground water), and ocean.  
  • GASEOUS FORM: Water vapor present in the atmosphere is the gaseous state of water, what two elements make up water. This moisture turns into rain drops after condensation. The earth gets rain fall after this in what two elements make up water.

GROUND WATER IN WHAT TWO ELEMENTS MAKE UP WATER

Water source of well, tube wells and hand pumps is ground water. These devices provide maximum amount of water to the people. Water comes to the devices from upper limit of ground water which we term as water table. The label of water depends upon the amount of rain water. Precipitated rain water seeps into the ground water to increase the water table. This process is called infiltration. Industries and  agricultural pumps draw out maximum ground water. At some places there is a storage of ground water in between hard rock layers under the water table. This source can be exhausted in time.

DEPLETION OF WATER TABLE IN WHAT TWO ELEMENTS MAKE UP WATER

There are various reasons of depletion of water table like scanty rain fall, deforestation etc, out of these some are man-made abd some are natural. Here I will discuss about different reasons of decreasing water table.

Increasing population in what two elements make up water

With the increase of population, we use water resource  for drinking, washing, cooking and cleaning. To fulfill the demand of residence, we construct a large numbers of houses, offices, shopping malls etc. By these construction, we get less open place where rain water can seep. Large number of under ground water is used for the construction. So more population leads to less water resources.

Industrialization in what two elements make up water

In heavy or light industries, water is used everywhere. Now in modern days we are increasing number of industries, as well as  decreasing water table.

Agricultural activities in what two elements make up water

To meet the increasing population, we have to produce more food. So we use maximum ground water for irrigation purpose. Canals from rivers contain less water due to scanty

 Deforestation in what two elements make up water

We do destructive fall of trees in large scale to accommodate the growing population. Other causes of deforestation are to grow food by turning the forest land into agricultural land and to provide spaces for industries. Another cause of loss of vegetation is overgrazing. If the soil is covered by green vegetation then flowing of water is reduced. It increases the absorption of water by soil. Cutting down of trees interferes the natural process of seepage of water into the underground. In this way there is the depletion of ground water table.

 QUESTIONS

Qs1: What is bawris?

Ans1: It is an ancient method of collecting water.

bawris used in storage of rainwater

We can find these structure still in old building like palaces and forts. These are large scale rain water storage system at the basement of buildings. With time, in what two elements make up water the bawris fell into disuse and garbage dumping place. Today the situation is that these places are useful for water source due to scarcity of rainwater.

Qs2:  In case of less water what are the effects we find in plants?

plant cannot do photosynthesis in drought
lack of water affects photosynthesis

Ans2: The effects are:

Water scarcity will effect nutrient uptake from soil by the plants.

Photosynthesis rate will decrease. It results less evolve of oxygen.

Transpiration rate will also decline, so atmosphere will contain less moisture which affect the water cycle.

SHORT QUESTION ON WHAT TWO ELEMENTS MAKE UP WATER

Qs3: The earth looks blue from space. Justify your answer.

 Ans3: 71% of earth surface contains water which imparts blue color to the earth.

Qs4: What does the slogan jal hai to kal hai ?

Ans4: This slogan means if we have water, we can think of future. It means there is no life possible without water.

Qs5: How does the reservoir of dam help us to manage water in what two elements make up water?

Ans5: The reservoir of dam or river can release water at our will. We can divert the flow of water at desired places whwre it is really needed and we can manage water resources effectively.

HIGHER ORDER THINKING SKILLS

Qs6: If we dug wells to get groundwater, then it dry up after sometime. What initiative we must take to get water fromit again?

Ans6: In this condition, the groundwater can be recharged through the process of infiltration. In this process we can replenish the groundwater table.

Qs7: What are the main causes of water scarcity in our country?

Ans7: The causes on what two elements make up water are:

 Changing of rural area into urban area rapidly.

Rapid growth of factories.

 Fast growth of population.

Qs8: There is lack of water due to a typical rain fall pattern in India. What is the pattern? There are two times of rainfall in certain part of country. Mention that place.

Ans8:  Due to uneven distribution of rainfall we use to face scarcity of water problem.  North east India gets rainfall through out the year causing flood, whereas desert of Rajasthan get very less rainfall resulting drought.  

 Kerala and other south Indian states get rainfall twice in the year.
