Finding the Northernmost Geographical Location

The question asks us to identify the northernmost geographical location among the given options: New Delhi, Kathmandu, Thimphu, and Dhaka. To determine which location is northernmost, we need to compare their latitudes. Latitude is a geographical coordinate that specifies the north–south position of a point on the Earth's surface. Locations further north have higher positive latitude values (in the Northern Hemisphere).

Comparing Latitudes of South Asian Cities

Let's consider the approximate latitudes of the capital cities listed:

• New Delhi, India: Approximately 28.61 degrees North latitude (\(\small{28.61^{\circ} N}\))
• Kathmandu, Nepal: Approximately 27.72 degrees North latitude (\(\small{27.72^{\circ} N}\))
• Thimphu, Bhutan: Approximately 27.47 degrees North latitude (\(\small{27.47^{\circ} N}\))
• Dhaka, Bangladesh: Approximately 23.81 degrees North latitude (\(\small{23.81^{\circ} N}\))

Determining the Northernmost Point

By comparing the latitudes, we can see which location is furthest north:

\(\small{28.61^{\circ} N \text{ (New Delhi)}}\)

\(\small{27.72^{\circ} N \text{ (Kathmandu)}}\)

\(\small{27.47^{\circ} N \text{ (Thimphu)}}\)

\(\small{23.81^{\circ} N \text{ (Dhaka)}}\)

The highest latitude among these is approximately \(\small{28.61^{\circ} N}\), which corresponds to New Delhi. Therefore, New Delhi is the northernmost geographical location among the given options.

Conclusion on Northernmost Location

Based on the comparison of latitudes, New Delhi has the highest positive latitude value among the given cities, placing it furthest north on the globe relative to the other options. Kathmandu, Thimphu, and Dhaka are all located further south than New Delhi.

Additional Information on Latitude and Geography

Latitude is a fundamental concept in geography used to pinpoint locations on Earth. It is measured in degrees, minutes, and seconds, ranging from \(\small{0^{\circ}}\) at the Equator to \(\small{90^{\circ} N}\) at the North Pole and \(\small{90^{\circ} S}\) at the South Pole.

• Lines of constant latitude are called parallels, and they run east-west around the globe, parallel to the Equator.
• Latitude helps determine the climate of a region; locations closer to the poles (higher latitude) generally experience colder climates than locations closer to the Equator (lower latitude).
• Longitude is another coordinate, measuring the east-west position relative to the Prime Meridian (\(\small{0^{\circ}}\) longitude).

Understanding latitude is essential for comparing the north-south positions of different geographical locations, as demonstrated in finding the northernmost city in this question.
