HELP!! PLS O.o Looking at the heat circulation in the ocean, what might happen to it if large amounts of cold water are added in
Nonamiya [84]

Answer:

The warm upper waters towards the poles from the tropic is done by surface circulation. If large amounts of cold water are added in the Polar regions as glaciers melt then the hot water cannot flow to the poles, the cold water will make the water very dense, which won’t allow warm upper waters to flow.

The effect it would have in the climate of my area is that it will increase the temperature of the local areas because of the rise in temperature of the surface ocean water.

What is the half-life of strontium-90? please explain your answer!
sveticcg [70]

The right answer is 28 years.

The half-life, or period of a radioactive isotope, is the time required for half of the nuclei of this isotope initially present to decay naturally.

One gram of pure 90 strontium has a radioactivity of 5.11 TBq. Its beta radiation is not penetrating, which makes it difficult to measure when it is in the soil or a matrix. It is very harmful when the particle is inhaled or ingested.
