Explanation:
- Statement 1: True. The atmosphere contains more freshwater than all the surface rivers combined due to the vast amount of water vapor it holds, which is part of the water cycle.
- Statement 2: False. Groundwater constitutes a significantly larger volume of freshwater than rivers.
- Statement 3: False. The polar ice caps hold the majority of the Earth's freshwater, more than lakes, rivers, and groundwater combined.
- Statement 4: True. The average ocean salinity is approximately 35 parts per thousand.

Consider the following statements:1. Atmosphere has more freshwater th...
Explanation:
Atmosphere has more freshwater than all surface rivers on the Earth: This statement is incorrect. The atmosphere contains only a small amount of freshwater in the form of water vapor, which is less than 1% of the total freshwater on Earth. Therefore, this statement is incorrect.
River freshwater is in more quantity than the groundwater: This statement is incorrect. Groundwater is the largest source of freshwater on Earth and accounts for about 30% of the world's freshwater resources, whereas rivers account for only about 0.2%. Therefore, this statement is incorrect.
The combined quantity of freshwater in lakes, rivers and groundwater is more than that stored in polar ice caps: This statement is correct. The combined quantity of freshwater in lakes, rivers, and groundwater is estimated to be about 91% of the world's freshwater resources, while the polar ice caps hold only about 2.15% of the world's freshwater resources. Therefore, this statement is correct.
The average salinity of the oceans is 40 parts per thousand: This statement is correct. The average salinity of the oceans is about 35 parts per thousand, which means that there are about 35 grams of dissolved salts in every kilogram of seawater. Therefore, this statement is correct.
Conclusion:
Therefore, the correct option is 'D' as only statement 3 is correct while the other statements are incorrect.
Consider the following statements:1. Atmosphere has more freshwater th...
Option 1 is correct according to ncert, atmosphere has more fresh water than rivers.
