What’s the disadvantage of using solar energy instead of energy from fossil fuels?

Expensive, Weather depended, large amount of land requirement.

Explanation:

Some of the major disadvantages of using solar energy instead of fossil fuels are as follows -  

a) It is very expensive. The initial cost of solar panels and solar cell is very high. Also the manpower required to set up and maintain a solar power plant is costly. Therefore, solar energy is costly at all the stages of energy production i.e establishment, operation, storage and maintenance

b) Unlike fossil fuels, solar energy mainly depends on the weather and climatic conditions. In cloudy and rainy days, the efficiency of solar system drops.

c) Solar power plant requires large amount of land for establishment. Hence  most of the time these power plants become unfeasible due to space requirement which is not the case with fossil fuels  

the answer is c) abandoned properties that are contaminated with hazardous materials.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
