Overfishing is a significant issue threatening marine ecosystems. According to the text, why is the practice of bottom trawling particularly destructive?

It specifically targets only large, endangered predator fish.

It introduces invasive species into new marine environments.

It catches everything in its path and destroys the seabed habitat.

It causes chemical pollution from the large fishing vessels.

None

A mid-ocean ridge is formed by which specific geological process?

The collision of two oceanic plates, with one bending downward.

Magma rising from the mantle as two plates move apart.

The horizontal sliding of two plates against each other.

Thick layers of sediment accumulating over millions of years.

None

Coral reefs require clear water to thrive. What is the primary reason for this requirement?

Clear water has a higher dissolved oxygen content necessary for coral respiration.

Predatory fish are less able to hunt in clear water, protecting the reef’s inhabitants.

Sediment in murky water can physically smother and kill the coral polyps.

Sunlight needs to penetrate the water for the symbiotic algae (zooxanthellae) to perform photosynthesis.

None

Organisms like phytoplankton, which are primary producers in the ocean, belong to which kingdom?

Animalia

Fungi

Monera

Protista

None

Which ocean floor mapping technique uses pulses of light, often from an aircraft, to measure the depth of shallower coastal waters?

Sound Navigation and Ranging (SONAR)

Subduction Zone Imaging

Satellite Altimetry

Light Detection and Ranging (LiDAR)

None

Which of the following factors would lead to a decrease in the salinity of ocean water?

Melting of glaciers and icebergs

Formation of sea ice

Low precipitation over the ocean

High rates of evaporation

None

Which type of tectonic plate boundary is primarily responsible for the formation of deep ocean trenches like the Mariana Trench?

Abyssal boundary

Transform boundary

Convergent boundary

Divergent boundary

None

The daily rise and fall of sea levels, known as tides, are primarily caused by the gravitational pull of which celestial body?

The Moon, because of its close proximity to Earth.

Both the Sun and Moon equally.

The Earth’s own rotation on its axis.

The Sun, because of its immense mass.

None

What is the primary mechanism behind the phenomenon of 'upwelling'

Gravitational pull from the moon causing deep water to rise.

Surface winds pushing warmer surface water away from a coastline.

The Coriolis effect forcing deep ocean currents towards the surface.

Volcanic activity heating the seabed and causing water to circulate upwards.

None
