Once the EIA screening process is completed, there are four possible decisions which can be taken in terms of the future/path of the proposed development. The four decisions are: a) go ahead; b) basic EIA required; c) full EIA required; and d) no-go.
Evaluate the following hypothetical scenarios and in each case select the most probable decision. Your answer should include the chosen decision and an explanation on what that decision entails, as well as a justification on why that decision is the most likely outcome.
Proposed developments:
2.1. A nuclear power station located close to a protected area. The proposed location is also known for the regular occurrence of seismic activity.

discuss the three keys to the recognition of landforms on contour maps. Give an example for each of the three keys

Nominal scale is ......
A) Order of data according to some criteria such as preferred vehicle where1- most and 5- least preferred (1- SUV,2-4×4,3-MPV,4-truck,5- bakkie). B) Has equal distance between scale units but with no absolute zero such as temperature measured in degrees Celsius which you can say 10 degree Celsius is colder than 20 degrees Celsius but not twice as cold. C) sets of categories such as for vehicle it is 4×4, SUV,MPV, passage r car, trucks, bakkies, forklifts, etc. D) Has equal distance between scale unit with an absolute zero (no negative values ) such as distance between two points A and B and A and C in kilometers. If the distance is 10km between A and B and the distance between A and C is 30km, then C is three times as far from A than B
