Answer:
Solar energy is a good energy source since it is good for the environment.
Explanation:
Solar energy needs solar panels with solar cells that transform the sun's energy into electricity. Thousands of them can be in desert areas where the sun impacts the majority of the day. Also, they can be on roofs and street lights. Solar panels are less dangerous than nuclear power plants. Also, they are a renewable source of energy and are cheaper than nuclear energy.

Explanation:
Soil compaction results from
A) the reduction or elimination of pore space in soil
B) the weight of heavy machinery on soil
C) livestock walking over soil
D industrialization
E all of the above
Explanation: ALL OF THE ABOVE:E
Compaction of soil can be defined as the compression of the soil particles into smaller volume which will reduce the pore space and it will provide more space for water and less space for air.
It can be done by many ways. Some of the ways are suggested here. The reduction of pore space in the soil.
The weight of heavy machinery on the soil will reduce the pore space of the soil.
The livestock walking also reduces the pore space of the soil and helps in soil compaction
Soil compaction results from all of the above (reduction or elimination, weight of heavy machinery on soil, livestock walking over soil, industrialization). Thus, option (e) is correct.
When soil particles are compressed, pore space is reduced and soil compaction takes place. Putting weight on the soil, which occurs frequently in agricultural areas due to foot traffic, livestock tramples, or the enormous weight of agricultural machinery, is the main factor in soil compaction.
Other factors that contribute to soil compaction include heavy foot traffic, cultivating and walking on damp ground in gardens, compression caused by heavy machinery, vehicles parked under trees, and any activity that puts pressure on the soil and weakens its structure.
Therefore, option (e) is correct.
