Answer:
Due to continuous global warming, the oceans tend to gain more heat and hence the temperature rises. In the current century, the heated conditions of the oceans can be threatful for the human population. Also, the increase in the sea levels will have serious consequences on the health of mankind and their quality of life.
The fossil record shows a sequence from simple bacteria to more complicated organisms through time, it is very reliable because it is physical evidence and by studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth.
Answer:option d
Explanation:Ocean acidification is the ongoing decrease in the pH of the Earth's oceans, caused by the uptake of carbon dioxide (CO. 2) from the atmosphere. Seawater is slightly basic (meaning pH > 7), and ocean acidification involves a shift towards pH-neutral conditions rather than a transition to acidic conditions (pH < 7).
