The technique called radiometric dating is based on

Geography
1 answer:
Dima020 [189]3 years ago
3 0

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.

Please help: What effect does eutrophication have in aquatic ecosystems?
Alisiya [41]

Answer:

The answer is D

Explanation:

an overabundance of nutrients primarily nitrogen and phosphorus which is in the water starts a process called eutrophication which makes it decrease. when the algae dies they are decomposed by bacteria. This process consumes the oxygen dissolved in the water which is needed by fish and other Aquatic Life to breathe.

It isn't C because it actually increases carbon dioxide not lower.

It isnt B because it does negatively impact aquatic vegetation but it is not beneficial for all aquatic animals

A isn't the the correct answer because eutrophication has nothing to do with sunlight into the ocean

So the only answer left which is correct is D

(I hope this helps you! have a wonderful day everyone!)

labwork [276]
The ozone layer protects us from the harmful emission of rays directly to the environment. Absent this added layer of protection we humans will be susceptible to various forms of cancer due to over radiation and eye problems such as cataracts. It is estimated that 10% of the world's population will face the consequences of ozone depletion this year and these numbers were continue to rise as time progresses.
