It’s summer and you have been planning to take a vacation in Naga City in Bicol where your grandparents lived so you bought a bus ticket early. While you were still in Manila a few days before your scheduled trip, you’ve heard from the news that Mt. Mayon in Albay has erupted and thousands of people were evacuated. Is it safe for you to still go on vacation in Naga?
A.Yes, because Mayon is a 2–3-hour drive from Naga. The lava can’t go that far and based on its past eruptions the people in Albay are the ones mainly affected but be prepared to encounter some traces of ash.
B.Yes, because Mayon is too far for the pyroclastic flow to reach Naga and the bus will never pass through Albay anyway so it’s safe to take the trip.
C. No, because it can ruin your vacation and cannot go to the beaches.
D. No, because ashes will surely be flown by the wind and can continue for weeks.
B. Yes, because Mayon is too far for the pyroclastic flow to reach Naga and the bus will never pass through Albay anyway so it’s safe to take the trip.
The following are the processes on how to generate electricity via geothermal power plant, arrange them in the proper sequence.
I. Cooling tower cools the steam, which condenses it back to water.
II. Cooled water is pumped back into the earth to begin the process again.
III. Wells are drilled deep into the earth to pump steam or hot water to the surface.
IV. When the water reaches the surface, the drop in pressure causes the water to turn into steam.
A. II, I, III, IV
B. III, IV, I, II
C. I, II, III, IV
D. III, I, IV, II
B. III, IV, I, II
