Question

Deep-ocean circulation currents are described as ____________ circulation.

  1. Ocean floor
  2. Thermohaline
  3. Sub-surface
  4. Interface

hintHint:

Thermocline circulation

The correct answer is: Thermohaline


    • The deep-ocean currents are driven by differences in the water's density, which is controlled by temperature (thermo) and salinity (haline). Hence, known as thermohaline circulation.
    • So, the correct option is b.

    The Westerlies are__________.

    • Westerlies are the Permanent winds that blow in the middle latitudes.
    • The winds that change their direction with onsets of different seasons are called seasonal winds.
    • Variable winds are those winds which blow in a small area and are related to the pressure systems.
    • Mesoscale winds are better known as local winds or regional winds. These wind channels extend over long distances around the Earth.

    What is the effect of altitude on temperature? 

    • Air at higher altitude is under less pressure than air at lower altitude because there is less weight of air above it.
    • So it expands and cools.
