Identify how scientists use radioactive isotopes by selecting the best answers from the drop-down menus. Archaeologists use radioactive isotopes to ___________ Scientists use radioactive isotopes in agriculture to_____________ Geologists use radioactive isotopes to ______________

Answer 1

Answer:

Archaeologist use radioactive isotopes to determine the ages of various objects, rocks and materials. This is called radioactive dating. Radioactive isotope Carbon-14 is widely used for this dating process.

Scientists use radioactive isotopes in agriculture to monitor or study the uptake and use of essential nutrients by plants from the soil. This helps to determine viability, productivity and nutritious ability of the plants on a piece of land.

Geologists use radioactive isotopes to trace leaks in underground water storage, pipes. Radioactive isotopes are effective tracers because their radioactivity can be easily detected.

Answer 2

Answer:

Explanation:

Archaeologists use radioactive isotopes for Radiometric dating which is typically a method of dating based on the rate of decay of radioactive isotopes present in all organic materials.

The radiometric dating technique tyat is Carbon-14 or radiocarbon is used widely in archaeology.

Scientists use radioactive isotopes in agriculture as research tools in the development of new strains of agricultural crops that are drought and disease resistant, of higher quality, have shorter growing time and produce a higher yield of produce.

Radioactive elements can be used to understand numerical age of geological materials like rock ages, composition, origin etc. on time scales as long as (and even longer than) the age of the Earth. The use of Radiometric dating is employed.
