Arrange the following Earth's water compartments in increasing order of the amount of the water they hold.
A. Rivers and streams
B. Fresh lakes
C. Atmosphere
D. Ice and Snow
Choose the correct answer from the following options given below :
A, C, B, D
To solve this question, we need to understand the relative amount of water held in each of the listed compartments of Earth's water system. Here, we are tasked with arranging these compartments in increasing order based on the volume of water they contain:
Thus, the correct order from the smallest to the largest compartment is Rivers and Streams, Atmosphere, Fresh Lakes, and Ice and Snow.
The correct option is therefore: A, C, B, D.
Given below are two statements : One is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : Although internal-combustion engines used in today's vehicles can be adapted to burn hydrogen, hydrogen powered combustion engines probably are not the future of hydrogen fuelled vehicles.
Reason R : It is more efficient to convert hydrogen energy directly to electricity using fuel cells.
In the light of the above statements, choose the correct answer from the options given below :
