Altimetric Frequency curve depicts :

Option 4 is the correct answer: Representation of Altitudes of Areas from sea level.

Explanation:

An altimetric frequency curve, also known as a hypsometric curve, is a graphical representation that shows the proportion of an area at different elevations above (or below) a datum, typically sea level. It plots altitude (elevation) on one axis and the percentage of the total area at or below that altitude on the other axis. This allows for a clear visualization of the distribution of landmass at various heights. The curve directly represents how much of a given area lies at a specific altitude relative to sea level. Therefore, it's a direct representation of the altitudes of areas from sea level.

Why the other options are incorrect:

1.  **Population distribution:** While altitude can *influence* population distribution (e.g., fewer people living at very high altitudes), an altimetric frequency curve doesn't directly depict population. It only shows the distribution of land area at different elevations, not where people live. Population distribution maps or graphs would be used for that purpose.

2.  **Rainfall distribution in different weathers:** Rainfall distribution is related to weather patterns, topography, and other climatic factors. An altimetric frequency curve focuses solely on the elevation of the land and does not provide any information about rainfall patterns or weather conditions. Rainfall distribution is typically represented using rainfall maps or graphs showing rainfall amounts over a specific area and time period.

3.  **Relief of Oceanic Basin:** While altimetry can be used to study the ocean floor (bathymetry), an altimetric frequency curve is generally used to represent the relief of *land* areas. While similar principles apply, the term "altimetric frequency curve" is more commonly associated with terrestrial landscapes. Bathymetric maps and profiles are used to represent the relief of oceanic basins. Furthermore, the term "altimetric" implies a measurement of altitude, which is typically referenced to sea level, making it more directly applicable to land elevations.
