NCEA Level 3 Earth and Space Science Practice Questions - New Zealand NCEA Level 3 Earth and Space Science Exam - NCEA Level 3 Earth and Space Science Practice Questions - New Zealand NCEA Level 3 Earth and Space Science Exam

Question 1

Which of the following primary mechanisms drives deep-ocean thermohaline circulation?

Density differences resulting from variations in seawater temperature and salinity Surface wind stress driven by the prevailing trade winds and westerlies Gravitational attraction between the Earth, Moon, and Sun causing tidal flow Geothermal heat flux from mid-ocean ridge hydrothermal vents

Correct Answer:

Density differences resulting from variations in seawater temperature and salinity

Question 2

How does the permanent thermocline in low-latitude (equatorial) ocean waters differ from high-latitude (polar) ocean waters?

Equatorial waters exhibit a steep, pronounced thermocline, whereas polar waters lack a permanent thermocline due to uniformly cold surface waters Equatorial waters have no thermocline because surface water is cold, whereas polar waters have a very steep thermocline Both equatorial and polar oceans have identical thermocline profiles regardless of latitude Polar oceans display a steep thermocline only during winter months due to intense ice melting

Correct Answer:

Equatorial waters exhibit a steep, pronounced thermocline, whereas polar waters lack a permanent thermocline due to uniformly cold surface waters

Question 3

In the Southern Hemisphere, how does the Coriolis effect alter the direction of moving ocean surface currents relative to wind direction?

It deflects moving ocean currents to the left of their path of motion It deflects moving ocean currents to the right of their path of motion It accelerates currents directly parallel to the wind vector without deflection It forces surface currents downwards into deep trench subduction zones

Correct Answer:

It deflects moving ocean currents to the left of their path of motion

Question 4

What is the direction of net water transport in the Ekman spiral within the Southern Hemisphere relative to the prevailing surface wind direction?

90 degrees to the left of the wind direction 90 degrees to the right of the wind direction 45 degrees to the left of the wind direction 180 degrees opposite to the wind direction

Correct Answer:

90 degrees to the left of the wind direction

Question 5

Which combination of wind direction and coastal orientation produces coastal upwelling along the western coast of a Southern Hemisphere landmass?

Northerly wind blowing equatorward along a west-facing coast, causing net offshore Ekman transport Southerly wind blowing poleward along a west-facing coast, causing net onshore Ekman transport Easterly wind blowing offshore from the land, dragging cold surface water inland Westerly wind blowing onshore from the ocean, creating a surface water wedge against the coast

Correct Answer:

Northerly wind blowing equatorward along a west-facing coast, causing net offshore Ekman transport
