Question 1
1 / -0

which of the following statements about the effects of ocean currents is true?

A
West coasts of continents in tropical and subtropical latitudes are characterized by warm waters and arid climates.

B
Warm currents flowing parallel to the east coasts of continents in tropical and subtropical latitudes result in cool summers and mild winters.

C
Mixing of warm and cold currents helps deplete oxygen levels in the ocean, negatively impacting marine life.

D
The best fishing grounds of the world are typically found in areas with uniform water temperatures and low plankton growth.

Solution

Mixing of warm and cold currents helps replenish oxygen and favors the growth of plankton, which are the primary food for fish populations. Therefore, the best fishing grounds are usually found in these mixing zones where favorable conditions for plankton growth exist.
Question 2
1 / -0

How do tidal currents differ from ocean currents?

A
Tidal currents are caused by winds, while ocean currents are caused by the moon's gravitational pull.

B
Tidal currents occur only in enclosed seas, while ocean currents occur in open oceans.

C
Tidal currents are caused by the rise and fall of tides, while ocean currents are continuous flows of water.

D
Tidal currents are influenced by atmospheric pressure changes, while ocean currents are influenced by temperature variations.

Solution

Tidal currents are caused by the rise and fall of tides, leading to temporary water movements, while ocean currents represent continuous flows of water in specific directions.
Question 3
1 / -0

Which of the following statements regarding tides in the Bay of Fundy is correct?

A
The tidal bulge in the Bay of Fundy is approximately 10-11 meters.

B
There are four high tides and four low tides every day in the Bay of Fundy.

C
The tide rises at a rate of approximately 240 cm per hour in the Bay of Fundy.

D
Tides in the Bay of Fundy occur within a 12-hour period.

Solution

The tide rises at a rate of approximately 240 cm per hour in the Bay of Fundy.
Question 4
1 / -0

What determines the height of spring tides?

A
Position of the sun with respect to the moon

B
Earth's rotation speed

C
Strength of the wind

D
Atmospheric pressure changes

Solution

The height of spring tides is determined by the position of the sun, moon, and Earth in alignment, resulting in higher tidal ranges.
Question 5
1 / -0

What provides energy to waves in the ocean?

A
Earth's magnetic field

B
Gravitational pull of the moon

C
Wind

D
Ocean currents

Solution

Wind provides energy to waves in the ocean, causing them to travel across the surface and release energy on shorelines.
Question 6
1 / -0

What influences the height of tidal bulges on Earth's surface?

A
Earth's magnetic field

B
Centrifugal force

C
Wind patterns

D
Depth of the ocean

Solution

The height of tidal bulges on Earth's surface is influenced by centrifugal force, which counterbalances the gravitational pull of the moon and sun, resulting in tidal variations.
Question 7
1 / -0

How do neap tides differ from spring tides?

A
Neap tides occur during spring, while spring tides occur during neap.

B
Neap tides have lower tidal ranges than spring tides.

C
Neap tides occur only in the Northern Hemisphere, while spring tides occur in the Southern Hemisphere.

D
Neap tides are caused by the moon, while spring tides are caused by the sun.

Solution

Neap tides have lower tidal ranges compared to spring tides and occur when the gravitational forces of the sun and moon partially cancel each other out.
Question 8
1 / -0

How do the shapes of bays and estuaries affect tidal magnitudes?

A
They have no effect on tidal magnitudes.

B
They decrease tidal magnitudes.

C
They increase tidal magnitudes.

D
They cause tidal currents to reverse.

Solution

The shapes of bays and estuaries can magnify tidal magnitudes, leading to increased tidal ranges and intensities.
Question 9
1 / -0

Which tide occurs when the Sun, Moon, and Earth are in a straight line, resulting in higher tidal ranges?

A
Neap tide

B
Semi-diurnal tide

C
Spring tide

D
Mixed tide

Solution

Spring tides occur when the Sun, Moon, and Earth are in a straight line, aligning their gravitational forces and resulting in higher tidal ranges.
Question 10
1 / -0

Where is a tidal power project located in India?

A
Sunderbans of West Bengal

B
Kerala backwaters

C
Mumbai coastline

D
Gujarat coast

Solution

A 3 MW tidal power project is under construction at Durgaduani in the Sunderbans of West Bengal, India, utilizing tidal energy to generate electricity.
