The steps of hydraulic fracturing have been placed in order as follows:
1. The targeted shale formation is drilled to the desired depth
2. The well is completed
3. Production begins with oil and gas flowing and fracturing commencing.
4. Well abandonment which entails leaving the land as it was initially..
<h3>What is hydraulic fracturing?</h3>
Hydraulic fracturing refers to the process of injecting a well with chemicals and other materials that are needed for it to release its oil content. Hydraulic fracturing often begins with the preparation of the well to be used for the purpose.
Next is the drilling of the target area. This is followed by the completion of the well, and the beginning of production. After production is completed, the well is now abandoned or returned to the way it was when production began.

Answer:
i. 3/5
ii. 2/5
Explanation:
Solving the problem by any of the students A, B and C is an independent event as solution by one does not restrict the other one from solving
However, the problem will be solved if even one of them solves the question
Now Probability of not solving the question by A, B and C are
PA (not solving a problem) - 1-1/3 = 2/3
PB (not solving a problem) - 1-1/4 = 3/4
PC (not solving a problem) - 1-1/5 = 4/5
ii) Probability of not solving - 2/3*3/4*4/5 = 2 *1/5 = 2/5
i) Probability of solving - 1- Probability of not solving
= 1 - 2/5 = 3/5
Earth's rotation causes air and water in the northern hemisphere to appear to move right and in the southern hemisphere to appear to move left
Climate change can worsen the intensity of tropical storms (such as hurricanes, typhoons and cyclones) in several ways, including by making record rainfall more likely and by causing sea levels to rise, which can raise the risk of storm surges.
