Afamily has a furnace that uses natural gas to heat their home. they are moving to an area that offers the option of using energy from a solar power plant to heat their home. which disadvantage will the family most likely face by making this switch? a less reliable production of heat higher costs for the monthly heating bill an increase in waste production smaller quantities of heat

The right option is; a less reliable production of heat

The energy from a solar power plant is the energy obtained from the sun’s radiation.  The solar energy is less reliable because it is weather dependent. The solar energy is mostly gathered when it is sunny. During cloudy and rainy days, the efficiency of the solar system is reduced, and also during the night, solar energy cannot be collected. Other disadvantages of the solar system include; it is costly, takes a lot of space, and it is associated with pollution.

not sure if this what   you'r looking for would be percent composition

b. lithosphere, asthenosphere, mesosphere   is the answer most likely
