Describe the division of the geologic time scale using terms eon epoch and period

1 answer:

5 0

The geologic time scale is referred to as the system of chronological dating which is related to geological strata to time. It is used by palaeontologists, geologists and earth scientists to describe the relationship of events and timing that occurs during Earth’s history. The primary division of time is defined as eons. Eons follow a sequence of the Archean, the Hadean and the Proterozoic which are referred as Precambrian superon.

Eons are divided into an era whereby those eras are subdivided into periods, ages, and epochs. Eon, epoch, period and ages correspond with eonothem, series, systems and stage which are mostly used to refer to layers of rock which then stretches to geologic time in the history of the earth.

Agricultural practices relating to irrigation have the tendency to reduce the water level of river basins.

<h3>What are the effects of irrigation agriculture on river basins?</h3>

Irrigation agriculture requires that crops are watered artificially and this requires a water source. Hence, waters in river basins suffer and this leads to a reduction in their levels.

Water quality is impacted by agricultural practices such as the use of agrochemicals and fertilizers. Agrochemicals are washed into water bodies and this impacts biodiversity life in water.

One conservation strategy to reduce the impact of this kind of agricultural practice would be to practice organic farming. A farming practice that is devoid of using agrochemicals or the ones that are not poisonous to biodiversity and are biodegradable.

11Alexandr11 [23.1K]

Answer:

Explanation:

The statement that best explains the result would be that <u>the rate of photosynthesis is greatest for direct sunlight and least for the infrared light.</u>

The DPIP will normally replace and play the role of NADPH in the light reaction of the process of photosynthesis. Hence, it will become colorless as a result of reduction and the rate of photosynthesis can be monitored based on the magnitude of the disappearance of the dark blue color.

It means that the more colorless the liquid in the illustration is, the more the rate of photosynthesis. <em>The color change moved from dark blue to clear colorless under direct sunlight, from dark blue to nearly colorless under indirect sunlight, and from dark blue to slightly lighter under the infrared light.</em> <u>This clearly indicates that the rate of photosynthesis is highest under direct sunlight and lowest under infrared light with the indirect sunlight having an intermediate rate. </u>

The correct option is B.
