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.
Usually, the main cause of climate change is the " greenhouse effect" which warm the earth's surface as a result of atmospheric pollution by gases, the particular greenhouse gasses such as carbon dioxide, water vapor, methane, ozone , and chlorofluorocarbon that heat from earth's surface is absorbed by atmospheric greenhouse gases that produces this difference between the definite surface temperature and the effective temperature is due to the atmosphere. the increased amount of gasses that absorbed heat is advance to had more heat being retained in the atmosphere and can increase the global average surface temperature,not only greenhouse effect that cause climate change the human aspects can also change earth's climate, human activities such as burning fossil fuels and deforestation, and it can be one causing global warming.
In the equation, the value of y will be different as a result of the signs that are used.
<h3>How to solve the equation</h3>
In the first equation, 5y + 10 = 25. To find the value of y goes thus:
5y + 10 = 25
5y = 25 - 10
5y = 15
y = 15/5 = 3
Also, 5y - 10 = 25
5y = 25 + 10
5y = 35
y = 35/5 = 7
The values of y are 3 and 7.
