Answer:

As explained below.

Step-by-step explanation:

  • The three major factors that help determine the flow of air at lower altitudes, are Coriolis force, convective currents and the presence of frictional force.
  • As we know the air in the troposphere consists of 99% of the moisture and dust and gases and hence most of the weather phenomena take place under or up to this layer hence known as homosphere.
  • The Coriolis force which related to the rotational spinning of the earth on its axis is a force that leads to the flow of air current and the movement of winds in right in the north and the left in southern direction.
  • The impact of the sun's rays have on the earth produced a convective current that warms up the equatorial zones and this warm air moves upwards and reaches the polar and the descent of the polar winds created a high and low-pressure belt, all of these factors are accompanied by the landscape of the earth.
