Answer:Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion.
Explanation:
NON CONVENTIONAL =
Energy generated by using wind, tides, solar geothermal heat and biomass including farm and animal waste as well as human excreta is known as non-conventional energy. All these sources are renewable or inexhaustible and do not cause environment pollution. More over they do not require heavy expenditure.
CONVENTIONAL=

Answer:
Passive solar houses.
Explanation:
Passive solar technology is the set of techniques aimed at the use of solar energy directly, without transforming it into another type of energy, for immediate use or for storage without the need for mechanical systems or external energy input, although it can be complemented by them, for example for their regulation.
Passive solar homes work best with open floor plans--reduced partitions from main rooms to minor rooms-- to facilitate the thermosiphing movement of solar heat from the south side through the rest of the house.
The interior surfaces that the sunlight falls upon are high density (thermal mass) materials, such as concrete, brick, stone, or adobe.
Rising heat wave on the south side of the building naturally heats up the roof terrace work areas and south facing sleeping rooms during winter.
