Question

E. Give short answers for the following questions.
1. Describe the general distribution of salinity in the oceans.
2. How do ocean currents influence climate in the coastal areas?
3. Name the main currents of the Pacific Ocean.
4. What is a tsunami? How does it affect life in the coastal areas?​

Answer 1

Answer:

1. The distribution of salinity in oceans is as follows: Ocean water is saline due to the presence of a large amount of dissolved salts, mostly sodium chloride or common salt.In general, salinity decreases towards the equator due to heavy rainfall. The dead sea in Asia has the highest salinity.
2. Warm and cold ocean currents can affect the climate of an area along the coast if the winds blow in from the ocean. Warm ocean currents heat the air above the water and carry the warm air to the land, increasing the temperature of the coastal region.
3. North Equatorial Current (Warm)

South Equatorial Current (Warm)

Counter Equatorial Current (Warm)

Kuroshio System (Warm)

North Pacific Drift (Warm)

4. In the coastal areas, a tsunami may appear as huge wall of water coming towards the coast. With its tremendous energy, the fast moving waves can crush houses and other structures in the coastal areas. Most of the deaths caused by a tsunami are due to drowning
