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.

Geological explanation of conditions of an erupting volcano
1. divergence plate( north american and european)
2. lies above a hotspot
Monitoring the volcanic activity
1. WHAT?? What about a volcano's activity do we monitor?
- volcanic temperature, water level, lakes, mass movement like rock falls, mud flow and seismicity
2. WHY?? Why do we monitor a volcano's activity?
-Plot geology maps- show changes before a volcano erupts
- Risks- health and death
- tourism, business, flights and daily activities
What materials spew out of the volcano?
- ash, smoke, lava, poisonous gases like carbon monoxide, sulfur dioxide and hydrogen chloride
One symptom geologists could rely on in preparation for an eruption- more powerful earthquakes, animals' strange behaviour, rumbling noise
The 2010 eruption of the Iceland volcano begin on 20 March, this caused many flights to and from Europe to be cancelled, creating the highest level of air travel disruption since World War 2. The second phase started on the 14 April, which resulted in an ash cloud which was estimated to be about 250 million cubic metres.
