Tides are the periodic phenomenon of alternate rise and fall in the sea level . They are resultant of the gravitational interaction of earth, moon and the sun.
a. Waves
b. Tides
c. Tsunami
d. None of the above
View Answer / Hide AnswerANSWER: a. Waves
Waves are caused by an alternate rise and fall of the sea surface. There are other types of waves that are not caused merely by winds, viz catastrophic winds and stationary winds.
a. Underwater volcanic explosions
b. Underwater landslides
c. Slippage of seafloor along earthquake fault
d. All the above
View Answer / Hide AnswerANSWER: d. All the above
Waves are caused by an alternate rise and fall of the sea surface. The oscillatory movements in the water produced by winds are called waves.
i. Salinity increases towards the poles.
ii. Salinity is minimum at tropics.
a. I only
b. ii only
c. both
d. none
View Answer / Hide AnswerANSWER: d. none
Salinity decreases towards the poles. Salinity is maximum at tropics.
a. Hypolimnion layer
b. Thermocline layer
c. Epilimnion layer
d. None of the above
View Answer / Hide AnswerANSWER: a. Hypolimnion layer
The ocean temperature determines the type and distribution of fauna and flora living in the water. There are three important layers and the cold layer that extends up to the ocean floor is hypolimnion layer.
