Answer:
The most recent eon is subdivided into three eras and eleven periods.
Explanation:
The geological time scale has been constructed so that it can help in better research and understanding of the past, as well as making it easier to distinguish the past and its characteristics at a certain time. There are larger and smaller divisions in the geologic time scale, with the eon being the largest unit, followed by era, and then period.
The most recent eon is the Paherozoic, starting from 542 million years ago and still going on. It is subdivided into three eras and eleven periods so far. The three eras are:
- Paleozoic
- Mesozoic
- Cenozoic
The eleven periods are:
- Cambrian
- Ordovician
- Silurian
- Devonian
- Carboniferous
- Permian
- Triassic
- Jurassic
- Cretaceous
- Tertiary
- Quaternary
Answer:
In effects research, primary effects are those which are immediate or more predictable while secondary effects are those which are subsequent or less predictable.
Explanation:
Answer:
107,768 ft³/hr
Explanation:
Given that :
FIELD A:
Runoff Coefficient (C1) = 0.55
Field size (s1) = 3 acre
FIELD B:
Runoff Coefficient (C2) = 0.75
Field size (s2) = 5 acre
Rainfall intensity (I) = 5.5 in/hr
We need to convert ;
Field size to ft²
1 acre = 43560 ft²
s1 = 3 acre = 43560 * 3 = 130,680 ft²
s2 = 5 acre = 43560 * 5 = 217,800 ft²
Rainfall intensity to ft/hr
1 inch = 0.0833 ft
5.5 in/ hr = (0.0833 * 5.5) ft/hr = 0.45815 ft/hr
Peak flow :
(C1 * s1 * I) + (C2 * s2 * I)
(0.55 * 130680 * 0.45815) + (0.75 * 217800 * 0.45815)
32929.0731 + 74838.8025
= 107767.8756 ft³/hr
