advantages and disadvantages of volcanism
·
Provide energy
Volcanoes provide resources for energy extraction, also
called geothermal resources. Heat from the earth's crust is
being converted to energy. The big advantages to this type of
energy are that it is very clean and the resources are nearly inexhaustible.
·
Fertile soil
When a
volcano erupts it throws out a lot of ash. At short notice this
ash can be very harmful to the environment, but on the long term the ash
layer, which contains many useful minerals, will be
converted to a very fertile soil. Nearly everywhere volcanoes are
located people use the rich soil for farming. Even after an
eruption people still return because of the fertile soil around the volcano.
·
Tourism
Volcanoes
attract millions of visitors every year, for different reasons. Around the
volcano may be warmbathing lakes, hot springs, bubbling mud pools and steam
vents. Tourism creates jobs in shops, restaurants, hotels and tourist
centers / national parks. Locals economies can profit from volcanism
throughout the year, whereas skiing, for example, has only a limited winter
season.
DISADVANTAGES OF VOLCANOES
•Sea -
during a volcanic eruption earthquakes happen, and tsunamis may be created.
Also, if it is a volcanic island, the island may be destroyed, and there is
no escape.
•Lava flow
- these are very slow moving, but destructive as they cannot be stopped and
they set fire to everything in their path.
•Pyroclastic
flow - these are impossible to outrun, travelling at about 300 km/h, and are
extremely destructive.
•Mudflow/lahar
- these are mud rivers that have the consistency of cement, and destroy
everything in their path, including buildings.

SUMMARY OF DIVERGENT
Beatrice Prior lives in a future version of Chicago where there are five distinct factions. Each faction thinks one virtue is best: Dauntless think bravery is keen, Erudite love knowledge, Abnegation is pro-self-sacrifice, Amity hearts friendship, and Candor is into telling it like it is. Beatrice grew up in an Abnegation family. But when she turns 16, she decides to join Dauntless—partly because they're cool (tattoos, piercing, leather jackets, love of Wuthering Heights); partly because she doesn't feel selfless enough to be a good Abnegation; and partly because her test result showed that she was Divergent, meaning she doesn't really fit in with any one faction.
But joining Dauntless isn't just about showing up and saying "take me." All the initiates have to train and compete to get into the faction. Along the way, Beatrice takes a new nickname—Tris—and meets a range of people. There are new friends like Al, Will, and Christina; new enemies like Peter and his evil minions; and new teachers, like the scary Eric and the hot Four. Tris has to compete to get into Dauntless, all while hiding that she's really Divergent. There's blood, violence, and some kissing (between her and Four). So, pretty much the usual high school experience.
Then, Tris figures out that the Erudite faction wants to overthrow the Abnegation government. And they're going to do so by mind-controlling the Dauntless army. But Tris doesn't get brainwashed (because she's Divergent), so she destroys the villain's plan, and rescues everyone. Except for her mom and dad, who die to help her. Bonus: the book ends with the city in complete chaos, so it's time to pick up the sequel.
