B. Fossil fuel combustion
C. Rock weathering
D. All the possible answers are correct
E. Reduced volcanic emissions

Explanation / Answer

1) The Coriolis effect causes things in motion to drift towards the right in northern hemisphere. So the correct answer is C.

2)Because of earth's tilt; the intensity of sunlight reaching the earth's surface changes with latitude and time of the year. It is because the lower the angle of sun's inclination; the constant energy is distributed on a bigger area and so less intensity and the position of sun changes throughout the day. So the correct option is D.

3) An El-Nino event reduces the upwelling of cold water off the coast of Americas. And so fishes either die or migrate to another areas where they found enough to eat.

So the correct answer is D i.e commercial fishing is especially profitable off the coast of Peru.

4) Volcanos causes long term global warming and hence the correct answer is option E.

5) Since the industrial revolution; the primary cause to the climate change is burning of fossil fuels and deforestation. Hence the correct answer is option B i.e fossil fuel combustion.
