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.
Meridians are perpendicular to every latitude<span>. ... All the other </span>longitudes are measured<span>, and named after the angle they make with respect to the center of the Earth from the intersection of the Meridian and the Equator. Since a sphere has 360 </span>degrees<span>, the Earth is divided into 360 </span>longitudes<span>.</span>
Answer:
The oceanic crust is forced under the continental crust and into the mantle. Crompression causes mountains to form on the continental crust. Material in the mantle melts as volatiles seep out of the oceanic crust. The molten material rises to the surface, forming a continental volcanic arc.
Explanation:
hey ur not stoopid it's just the teachers
The answer is “D” A volcano was nearby at one time
Power is a function of voltage times the volume of electrons (current). Power is the ability to do work and is measured in Watts. The higher the voltage the more power you have with the same current.
