Reflection on geography trip- 4 September 2010

The geography trip was fun for me, especially in the company of my classmates. Although it was a steep climb, Bukit Timah hill was an excellent exercise workout for me! We learnt about the three different layers of a tropical rainforest. Th emergent, canopy and sparse undergrowth. I also saw a few lianas that twisted around the branches of other trees. It was all pretty interesting. Before climbing up the steep slope, there were monkeys all around. On the pathway, trees and roofs. However, as we climbed up the slope, the monkeys were nowhere to be seen! I really, really wonder why. When we finally reached the top of the hill, we had to sketch three leaves. When nearing the end of the trip, we happened to come across a granite quarry and the reservoir, it was beautiful! All in all, the trip was thoroughly enjoyable especially the silly monkeys and the laughter and jokes from my friends.

Note: There are pictures above that I took during the trip as well as the pictures of my sketches.

Hi. As I did not really do my data table, it is inaccurate. Therefore, I did not put it up.
Reflection: I think that this exercise is not really easy. Especially since I have to do it everyday ( although I did not do it regularly). I am a forgetful person and thus i seldom remember to take down the temperate on the different days.

my data table

Day(degree Celsius)	Maximum temperature	Minimum temperature	Daily temperature difference
Saturday	29	27	2
Sunday	30	29	1
Monday	28	28	0
Tuesday	29	28	1
Wednesday	32	29	3
Thursday	28	25	3
Friday	29	28	1
Saturday	28	27	1
Sunday	32	30	2
Monday	29	26	3
Tuesday	27	27	0
Wednesday	32	31	1
Thursday	28	24	4
Friday	30	29	1

Mean average temperature: 1.97

Reflection: It was quite hard to remember to go and take down the temperatures and I usually remembered to do so only in the middle of the night. I think the reason for the pretty low difference in temperature was due to the fact that there was strong wind all day long.

The geology of Iceland is unique and of particular interest to geologists. Iceland lies on the geologic rift between the Eurasian plate and North American plates.--- The volcano erupts because of diverging plates of North American plates in the south and another in the east.

Monitoring the Volcano:
-what to monitor?
Volcanic temperature, water level, lakes, mass movements like rock falls, mud flow, seismicity.
-why must we monitor?
plot geology maps- show changes before volcano erupts.
Volcanoes have their benefits and down sides.
risks- health and death, tourism, flights, business, daily activity.

what materials spew out of a active material? ash, smoke, lava, liquid and solid and gases. For gases, there is mostly steam, and poisonous gases can escape too.

What is one symptom geologists can rely on in preparation for an eruption?

There will be massive earthquake before an eruption. The scientists will go an observe rocks near the volcano areas, to see if the rocks are “strained.”

I've done a bit more research on monitoring:
Another term to describe volano monitoring is observation. The observation mostly takes not of the systematic seismicity(movement of the globe) and other physical changes, earthquakes, volcanic gas and conditions of the water cycle during eruptions. When a volcano is observed erupting, geologists characterize the volcano's eruptive behaviour. They also try to identify the main reason why the volcano erupts. The main reasons are mostly because of the different kinds of materials that have been deposited at various places, which may be hazardous. Because geologists observe these moments, it is possible to anticipate eruptions.
An example of volcanoes that have been observed or are being observed are Mount Cayley, Silverthrone Caldera and Mount Hooloo.
