Why the quality of water is deteriorating? (Speak this answer into the response)

Answer explanation

Quality of water is deteriorating because

                          i.        River water, which is our primary source of water, gets contaminated due to various reasons such as direct disposal of sewage by municipalities, excessive discharge of industrial pollutants, use for daily chores like washing, bathing, livestock bathing, garbage disposal, etc.

                        ii.        Water sourced from groundwater too has deteriorated due to the excessive use of pesticides & insecticides in agriculture, which seep into the groundwater as well as get washed away into the rivers.

Answer explanation

Write a short note on Tsunami?

Ans. Tsunami

                        i.        Tsunami is a Japanese word that means “Harbour waves” as the harbours get destroyed whenever there is tsunami.

                       ii.        An earthquake, a volcanic eruption or underwater landslides can shift large amounts of ocean water.

                      iii.        As a result a huge tidal wave called tsunami, that may be as high as 15m., is formed. The largest tsunami ever measured was 150m. high. These waves travel at a speed of more than 700 km. per hour.

                     iv.        The tsunami of 2004 caused wide spread damage in the coastal areas of India. The Indira point in the Andaman and Nicobar islands got submerged after the tsunami.

Write a short note on ocean currents? What is the first statement of the audio clip?

• Ocean Currents                Ocean currents are streams of water flowing constantly on the ocean surface in definite directions.

• The ocean currents may be warm or cold. Generally, the warm ocean currents originate near the equator and move towards the poles.

• The cold currents carry water from polar or higher latitudes to tropical or lower latitudes. The Labrador Ocean current is cold current while the Gulf Stream is a warm current.

• The ocean current influence the temperature conditions of the area. Warm currents bring about warm temperature over land surface.

• The areas where the warm and cold currents meet provide the best fishing grounds of the world.

What are the major movements of ocean water? What is the first statement of the video clip?

• Introduction to tides Ocean currents and

  waves. oceans one of the most intriguing forces of nature are truly vast and majestic resources

• that contains many beautiful

  plant and animal species. For thousands of years, people have depended on oceans as their source of food and a highway for trade

• people at one time believed that the ocean floor was smooth and flat. But in the 1920s scientists began mapping the ocean flows using instruments called Echo Sounders that measured the ocean depth with the help

  of sound waves

• The instruments used

  proved that the ocean flow had dramatic physical features such as huge mountains, deep canyons, steep cliffs, and wide plains
