Answer: (d)
Dolphin ridge and challenge ridge area in the Atlantic Ocean. Dolphin ridge is in North Atlantic Ocean while Challenge ridge is in South Atlantic Ocean.
Cocos ridge is in the Pacific Ocean.
South-East Indian ridge is in the Indian Ocean.
Lomonosov ridge is an unusual underwater ridge of continental crust in the Arctic Ocean.
Answer: (d)
Dolphin ridge and challenge ridge area in the Atlantic Ocean. Dolphin ridge is in North Atlantic Ocean while Challenge ridge is in South Atlantic Ocean.
Cocos ridge is in the Pacific Ocean.
South-East Indian ridge is in the Indian Ocean.
Lomonosov ridge is an unusual underwater ridge of continental crust in the Arctic Ocean.
Answer: Option C. -> Both A and R are true and R is the correct explanation of A.
Answer: (c)
The circum-Pacific belt or The Ring of Fire is a major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur.
In a 40,000 km (25,000 mi) horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and/or plate movements. It has 452 volcanoes (more than 75% of the world’s active and dormant volcanoes).
About 90% of the world’s earthquakes and 81% of the world’s largest earthquakes occur along the Ring of Fire. The next most seismically active region (5–6% of earthquakes and 17% of the world’s largest earthquakes) is the Alpide belt, which extends from Java to the northern Atlantic Ocean via the Himalayas and southern Europe.

Answer: Option C. -> There will be no North-East Atlantic fishing grounds
Answer: (c)In absence of cold Labrador current there will be no North East Atlantic fishing ground.
Answer: (c)In absence of cold Labrador current there will be no North East Atlantic fishing ground.
Answer: Option D. -> Seamounts
Answer: (d)
Answer: (d)
Answer: Option C. -> North Sea - Baltic Sea
Answer: (c)
Answer: (c)
Answer: Option B. -> Gravitational potential energy
Answer: (b)
Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun and the rotation of the Earth.
Tidal barrages make use of the potential energy in the difference in height (or head) between high and low tides. When using tidal barrages to generate power, the potential energy from a tide is seized through the strategic placement of specialized dams.
When the sea level rises and the tide begins to come in, the temporary increase in tidal power is channelled into a large basin behind the dam, holding a large amount of potential energy.
With the receding tide, this energy is then converted into mechanical energy as the water is released through large turbines that create electrical power through the use of generators
