The Western Himalayan region (Jammu & Kashmir, Himachal Pradesh, Uttarakhand) has distinct geographical, climatic, and socio-economic characteristics. Understanding these features helps evaluate which statements are correct.
Step 1: Statement 1
“The chief water resources are perennial rivers.”
• The Himalayas are the origin of major rivers like Ganga, Yamuna, and Indus.
• These rivers are perennial (flow throughout the year).
Hence, Statement 1 is correct.
Step 2: Statement 2
“Fruits like apples are grown in abundance.”
• The cool climate is highly suitable for temperate fruits.
• Apple orchards are widely found in Himachal Pradesh and Kashmir.
Thus, Statement 2 is correct.
Step 3: Statement 3
“Population is generally urban based and economically settled.”
• The region is mountainous with difficult terrain.
• Population is mostly rural and scattered.
• Economic development is limited due to accessibility issues.
Therefore, Statement 3 is incorrect.
Step 4: Statement 4
“Summer is mild and winter is severe.”
• Due to high altitude, summers remain pleasant.
• Winters are extremely cold with snowfall.
Hence, Statement 4 is correct.
Final Conclusion:
Correct statements are:
\[
1, 2, 4
\]
\[
\boxed{1, 2 \text{ and } 4}
\]
