Correct Answer <span style="">Only A and D</span>

Only about three percent of Earth's water is freshwater.

  • Of that, only about 1.2 percent can be used as drinking water; the rest is locked up in glaciers, ice caps, and permafrost, or buried deep in the ground.
  • Most of our drinking water comes from rivers and streams.
  • Out of 71% of water, 97% of water is saltwater which is present in oceans, seas, and saltwater lakes.
  • Only 3% of water present on earth is freshwater, out of which 2% is frozen in the form of ice caps and glaciers.
  • We can only use rest 1% water for our daily needs.

Additional Information

  • Water circulates in three forms- solid, liquid and gas.
  • In solid form water is present as snow, ice, as ice caps in the poles of earth, in mountains, and glaciers.
  • In liquid form, water is present in oceans, lakes, rivers, and ground water.
  • In gaseous form, water is present as water vapor in the air.

Modern civilisation is completely dependent on energy, which has therefore to be abundant and also economical. About 85% of the world's energy is supplied by oil, coal and natural gas while nuclear, hydro, wind and solar power and biomass supply the rest. Coal, nuclear and hydro are used primarily to generate electricity while natural gas is widely used for heating. Biomass is used both for heating and cooking. The wind and solar power is the future's hope as they are sustainable energy sources. Oil powers almost all machines that move and that makes oil uniquely versatile. Oil powered airplanes carry 500 people across the widest oceans at nearly the speed of sound. Oil powered machines produce and transport food. Oil powered machines are ubiquitous. Clearly, we live in the age of oil but it is drawing to a close. According to data available if oil production remains constant until it's gone, there is enough to last 42 years. Oil wells will produce less as they become depleted, which will make it impossible to keep production constant. Similarly natural gas and coal will last another 61 years and 133 years respectively. Naturally, as they become scarce, they become expensive, leading to a worldwide energy crisis. If we are to survive on this planet, we have to make a transition to sustainable energy sources. The transition may be willy-nilly or planned - the choice is ours. The dawning era of limited and expensive energy will be very difficult for everyone on earth but will be even more difficult if it is not anticipated. It is of utmost importance that the public and policymakers understand the global energy crisis and act in tandem to ensure that the species 'homo sapiens' does not become extinct. The energy sources of the future are
