The Gulf Steam
---------------------
Answer:
2.62 years
Explanation:
The half life of a material is the time taken for half of the number of radioactive atoms in a radioactive material to remain.
If a radioactive material is cut into pieces, each piece has the same half life as the whole material.
Hence, if Strontium-147 is cut into pieces, each piece will have a half life of 2.62 years, just as the whole material.
The correct answer is C. The burning of fossil fuels.
Explanation
The carbon cycle is a cycle in which carbon interacts with the biosphere, the lithosphere, the hydrosphere, and the Earth's atmosphere. Knowledge about this carbon circulation makes it possible to appreciate human intervention in the climate and its effects on climate change. This cycle makes life on Earth possible because the plants consume carbon dioxide, however, the balance of this cycle has been altered by the massive use of fossil fuels such as oil, gasoline, and gas. This alteration causes the atmosphere to deteriorate causing the sun's rays to directly penetrate the earth, on the other hand, it causes the greenhouse effect to increase, causing the earth's temperature to rise. So, the correct answer is C. The Burning of fossil fuels.
They are both on the end of the Pacific rim. They both have an above average number of volcanoes, and they are steeper and more narrow then other mountain ranges. This is a result of their both straddling and colliding continental plates and being on top of very active geological fault lines.
