Answer:
Due to erosion.
Explanation:
An unconformity refers to a type of geologic contact that occurs boundary between rocks. The main causes of Unconformities is erosion, wears away rocks and rock deposits never form. The most common cause of unconformity is erosion in which the younger rocks spread on older rocks with the passage of time. In Cardenas layer, erosion is also occurs that leads to unconformity in that region which leads to the formation of boundaries in the rocks.
Answer: Mining and quarrying can be very destructive to the environment. They have a direct impact on the countryside by leaving pits and heaps of waste material. The extraction processes can also contaminate air and water with sulfur dioxide and other pollutants, putting wildlife and local populations at risk.
4 men x 8 days = 32 days work content & 6 women x 8 days = 48 work content
6 women at 1/400 per day x 8 days is 48/400. 352+ so 1 mans daily output is 11 work units per day x 4 men = 44 work output per day x 8 days = 352 total work output
3 men x 10 days = 30 days work content & 7 women x 10 days = 70 work content
1 man work output is 11 x 3 men x 10 days = 333 work units
one woman’s work output is 1/400 per day x 7 women = 7/400 per day x 10 days = Total of 70 work output plus men’s output of 330 = 400 work units.
10 women x 40 days = 400 work content
so if 10 men carried out the work its 11 x 10 men = 110 work units per day
400 work units + 110 work units per day = 3.6363 days work for 10 men.
1 women daily work output = 1/400 unit per person x 10 women or 10/400 work units per day so 10 x 40 days
4 Men & 6 Women = 8 days (men = 4 x 8 x 11 = 352)( 6 x 8 x 1/40 = 48/40
3 Men & 7 Women=10 days (men = 3 x 10 x 11 = 330)(7 x 10 x 1/40 =70/40)
10 women at 1/400 each per day x 40 days is 400 work units
while 10 men x 11 units is 110 units per day so for 400 units it’s 3.6363 days
1 man is equal approximately to 11 Women
10 men can do job in 3.6363 days x ratio of 11 =
Answer: It will taken 10 women x 40 days to complete the same job.
