Solar ponds
A. produce potable water
B. are thermal energy collectors
C. use salt gradient to inhibit heat loss
D. are used for swimming in cold regions
E. produce heated water
Choose the correct answer from the options given below:

Correct option is B

Solar ponds are large-scale solar collectors that capture and store thermal energy. They use a salt gradient to prevent heat from escaping, allowing the water at the bottom of the pond to remain heated. Solar ponds are not typically used for potable water production or swimming but are used to produce heated water, which can be harnessed for various industrial applications.
B: Are thermal energy collectors – This is true; solar ponds collect and store thermal energy.
C: Use salt gradient to inhibit heat loss – A salt gradient prevents heat loss by limiting water convection, making this true.
E: Produce heated water – Correct; solar ponds generate heat that can be used for various purposes.
Information Booster:
A: Produce potable water – Incorrect. Solar ponds are not designed for desalination or producing potable water.
D: Are used for swimming in cold regions – Incorrect. Solar ponds are industrial and not typically used for swimming.
