सारांश
Latitude measures angular distance north or south of the Equator; longitude measures angular distance east or west of the Prime Meridian.
मूल विचार
प्रणाली को समझें
Latitude measures angular distance north or south of the Equator; longitude measures angular distance east or west of the Prime Meridian.
क्यों और कैसे होता है
कारण और संदर्भ
A spherical Earth requires angular coordinates to identify position consistently. Latitude is tied to the Equator and the changing angle of solar incidence, while longitude is tied to Earth's rotation and therefore provides the basis for local-time differences.
यह कैसे काम करता है
First, latitude is measured north or south from the Equator along a meridian. Next, longitude is measured east or west from the Prime Meridian along an arc. Their intersection gives a coordinate, while the longitude difference is converted into local-time difference as Earth rotates.
मुख्य तथ्य
- Equator is 0° latitude; poles are 90°N and 90°S.
- Prime Meridian is 0° longitude and passes through Greenwich.
- One degree of longitude equals four minutes of time in local-time calculation.
ज़रूरी शब्द
- parallel

स्थापित आँकड़े
- Equator is 0° latitude; poles are 90°N and 90°S.
- Prime Meridian is 0° longitude and passes through Greenwich.
उदाहरण और केस स्टडी
- A coordinate such as 23.8°N, 90.4°E locates Dhaka approximately.
कारण और घटक
- A spherical Earth requires angular rather than only linear location measures.
- The Equator provides the reference for latitude.
- The Prime Meridian provides the reference for longitude.
प्रभाव और महत्व
- Coordinates allow mapping, navigation, surveying and GIS location.
- Latitude helps explain insolation and climate zones; longitude underpins time calculation.
- Meridians converge, so the length of one degree of longitude decreases toward the poles.

BCS लिखित विश्लेषण
एक विश्लेषणात्मक उत्तर बनाएँ
- Distinguish latitude as a north-south angular measure from longitude as an east-west angular measure.
- Explain why latitude has climatic significance while longitude has a direct time-zone relationship.
- Apply the coordinate system to Bangladesh's location and standard meridian.
आम गलतफ़हमियाँ
- Latitude lines do not converge; meridians do.
- Longitude determines time difference, not latitude.
