The Western Ghats act as a barrier to southwest monsoon winds, causing orographic rainfall on the windward slopes.
Laterite soil forms through the chemical weathering of rock in areas with high rainfall and high temperatures, typical of the Western Ghats region, leading to the leaching of silica and concentration of iron and aluminum oxides.
Mumbai's rise as a major port was due to its excellent natural harbor (Bombay Harbour), substantial British capital investment, establishment as the capital of Bombay Presidency, and deliberate colonial infrastructure development.
Buddhism spread in Maharashtra particularly in inland plateau regions and along trade routes where Ashoka's edicts and missionaries were active, as evidenced by early Buddhist cave monasteries.
The Brahmagiri and surrounding plateau regions of north Maharashtra have a semi-arid climate with deciduous forests, receiving moderate rainfall and experiencing significant seasonal temperature variations.
During the British period, Maharashtra experienced population growth due to improved public health measures and reduced famines, but this growth was unevenly distributed, with major cities like Bombay growing rapidly.
The Satavahanas controlled major ports on the western coast and key internal trade routes, enabling them to facilitate trade in textiles, spices, and other goods, as evidenced by Roman coin finds.
Khandesh's strategic location connecting North and South India made it valuable for Bahmani Sultans, Mughals, and later the Marathas, each controlling it at different historical periods.
Burhanpur was a major textile trading center during the Mughal period, famous for its muslin and cotton exports, and served as an important commercial hub connecting the Deccan to other regions.
# Orographic Lifting and Rainfall Distribution in Konkan Region
Orographic lifting causes air masses to rise over geographical barriers, cooling and releasing moisture as precipitation on windward slopes.
## Step 1: Understanding Orographic Lifting
Orographic lifting occurs when moist air from the Arabian Sea is forced to rise over the Western Ghats mountain range during the Southwest Monsoon. As air rises, it cools adiabatically and loses its moisture-holding capacity.
## Step 2: Konkan Region's Geographical Position
The Konkan coastal region lies on the windward (western) side of the Western Ghats, directly exposed to moisture-laden Arabian Sea winds. The Western Ghats act as a natural barrier that forces this air upward, maximizing precipitation on the coastal slopes before air descends on the leeward side.
The Konkan region receives higher rainfall (2000-3000mm annually) compared to the Western Ghats interior due to continuous orographic lifting of moisture-rich monsoon winds along the coastal slopes.
Correct Answer: (A) Orographic lifting — This is the primary geographical factor responsible for the Konkan region's higher rainfall compared to inland areas.
