Answer:
D) the steady, clocklike decay of certain radioactive isotopes over time.
Explanation:
Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks.
For example, when rocks are formed, such as igneous rocks (formed when molten rocks cools), certain radioactive atoms are trapped inside the rocks during this formation process. Then these radioactive atoms decay over time.
The age of the rock can be estimated by comparing the occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.
From the options;
A) this is about the formation of the radioactive molecules and not about radiometric dating
B) this is radiocarbon dating (cabon dating/carbon-14 dating)
C) the <em>assumption </em>is wrong since the radioactive isotopes decays not accumulate.
D) the corect option as I explained earlier.
Answer:
a. prevention, minimization, reusing, recycling, energy recovery, disposal
Explanation:
The waste hierarchy is a concept used in solid waste management, which consists of identifying the basic strategies and their respective importance for waste management. According to the hierarchy, waste prevention, or reduction, is at the top, so it is the most important factor. It is followed by reuse, recycling and, finally, recovery, the landfill being the last option suggested for the destination of solid waste.
The international division of labor - specialization of individual countries in the production of certain products.The international division of labor based on the differences between the countries in the natural and climatic conditions, geographical location, natural resources and energy sources.At the same time the world united in a single trade and economic system that allows you to share the most products with each other.
Answer:
I say the correct answer is B. Perils.
<span>The most famous example of a cylindrical projection is the mercator. The mercator is famed for having a standardised projection, although still faces the same problems as other cylindrical projections in that there is a distortion of the map near the poles.</span>
