Answer:
D. physical weathering
Explanation:
The geological process that initiates and leads to the breaking of the rocks is termed as the physical weathering. In this process, the chemical composition of the rocks do not undergo any change. The process of breaking of the rocks is both gradual and sudden. The movement of the earth, the change in the temperature, the rise and fall of the water level, the presence of ice rocks for longer duration of the time, and the melting of the snow are some of the reasons which causes the physical weathering.

Explanation:
Answer:
Renewable Energy Resources.
Explanation:
Unlike fossil fuels which cannot be recovered when destroyed, these sources of energy can be recovered by a means of recycling . Recycling here reduces solid wastes which is one of the causes of land pollution.
Hydroelectric schemes can only be built in mountain regions where rainfall and rivers are plentiful which involves upset of aquatic ecosystem. This poses a dangerous pollution problem though.
Wind generators and solar panels are not very efficient energy producers. However, future schemes for producing solar energy via solar satellites are promising.
