2. The velocity of a river in its lower course is low.
3. The delta sometimes develops in a river's lower course.
4. Much of the river water is drawn for irrigation in the lower course.
Discuss
Answer & Solution
Answer: Option C

The best way of conservation of water resources is
Discuss
Answer & Solution
Answer: Option D
Solution:
All the above given points are worthy so as to conserve water. As rain water is the pure water, it can be stored & utilized as per the needs.

Consider the following statements:
1. Temperature of surface water is comparatively higher in the northern hemisphere than in the southern hemisphere.
2. The isotherms in the southern hemisphere are not regular and do not follow the latitudes while they (isotherms) are regular and follow the latitudes in the northern hemisphere.
Which of the statement(s) given above is/are correct?
Discuss
Answer & Solution
Answer: Option A
Solution:
Temperature of surface water is comparatively higher in the northern hemisphere than in the southern hemisphere. The temperature of ocean water varies in the northern and the southern hemispheres because of dominance of land in the former and water in the latter. The oceans in the northern hemisphere receive more heat due to their contact with larger extent of land than their counter­parts in the southern hemisphere and thus the tempera­ture of surface water is comparatively higher in the former than the latter.
69
Consider the following statements:
1. On the planet Earth, the fresh water available for use amounts to about less than 1% of the total water found.
2. Of the total fresh water found on the planet Earth, 95% is bound up in polar ice caps and glaciers.
Which of the statements given above is/are correct?
Discuss
Answer & Solution
Answer: Option B
Solution:
Statement 1: This statement is incorrect. The total fresh water available for use on Earth is estimated to be around 2.5% of the total water, not less than 1%. This water is found in various sources such as rivers, lakes, and groundwater.

Statement 2: This statement is correct. Around 95% of the total fresh water on Earth is stored in polar ice caps and glaciers. This frozen water is not readily available for immediate use and is mostly locked in these ice formations.

Therefore, the correct answer is Option B, which means only Statement 2 is correct.
