I help other scientists to predict where lava from
the volcano will flow next and how fast.

mountain causes far more damage.

1 Fred Spears works in a wildlife park looking after wild animals; loves nature and spends his holidays climbing mountains
2 Susan Kelp has studied geology at university; very interested in volcanoes; has visited Mount Etna in Sicily, Italy
3 Charles Wild is a medical doctor; works in a laboratory doing research on disease; loves adventure holidays; wants to analyse volcanic samples
Look at these three people who would like to study volcanoes. Which one would you choose to become a volcanologist Give your reasons.
Fred Spears:
He has the interest but not the qualifications. So he is not a good choice to become a volcanologist.
Susan Kelp:
She has studied geology and has an interest in volcanoes. She has all the necessary qualifications but she does not have practical experience devising experiments and analyzing data.
Charles:
He is a medical doctor with an interest in volcanoes. He has experience of conducting experiments but does not have the specific qualifications needed to become a volcanologist.
So
I would choose Susan Kelp because she has the necessary qualifications and the interest. Although she has not yet conducted experiments she will either have learned the techniques during university course or be able to learn them on – the – job. She seems to be the most suitable
candidate.
