Arrange the following zones in ascending order in terms of their...

The latitudinal zones from the equator towards the poles are arranged as follows:

Equatorial zone: Located roughly between $0^{{}^{\circ}}$ and $10^{{}^{\circ}}$ latitudes.

Tropical zone: Extends roughly from $10^{{}^{\circ}}$ to $23.5^{{}^{\circ}}$ latitudes.

Midlatitude zone: Located roughly between $30^{{}^{\circ}}$ and $60^{{}^{\circ}}$ latitudes.

Subarctic zone: Extends roughly from $50^{{}^{\circ}}$ to $70^{{}^{\circ}}$ latitudes.

Arranging them in ascending order of their latitudes (from lowest to highest) gives the sequence Equatorial zone, Tropical zone, Midlatitude zone, and Subarctic zone.

This corresponds to the code $1 - 4 - 2 - 3$.

Answer: 1 – 4 – 2 – 3
