Sulphor (S): (3*1)=3
Oxygen (O): (4*3)+(3*1)=15
Answer:
A. Steep hillside, little vegetation, strong downpours
Explanation:
between a steep hill and a flat valley, the hill is more likely to be affected because of gravity. with a valley theres less places for the dirt to actually move to. So C and D are not correct
a lack of vegetation and heavy downpour is the perfect condition for erosion. plants' root system makes dirt and rock more stable. without a lot of roots to hold the dirt in place and absorb water before it runs over the rocks and breaks them down, heavy rain would be a lot more likely to erode the area. so B isnt right either
This is true as some parts cannot be checked but the radioactive substances can be used in x-rays
