After reading my classmates observations it became more clear and I understand the reason behind the different patterns we observed. Based on the observations, I agree that the plate boundaries should be classified in the categories of ocean-continent, ocean-ocean-, and continent-continent. Within these categories we have spreading zones,…[Read more]

My group and I have come up with similar observations and from our answers, it can be seen that a classification system can be based on where one plate boundary meets another plate boundary. This being, ocean-ocean, continent-continent and ocean-continent. We saw that for volcanoes, most of them occur at an ocean-continent boundary, therefore, we…[Read more]

I agree thoroughly with Natalia on the fact that after reading all the observations collected by our group on the patterns of volcanoes, earthquakes, topography, and seafloor age relative to plate boundaries, it becomes clear that there should be 3 distinct categories for our boundary classifications. Those of course being ocean-ocean,…[Read more]

The observations suggest that boundaries can be classified by where plates are meeting with other plates. At Ocean-Continent boundaries, where plate boundaries are meeting on the coast of a continent, there is a high concentration of volcanoes and earthquakes occurring in a curvilinear pattern along the line of the boundary. At these boundaries…[Read more]

1. Are volcanoes present at ALL boundaries?
– Not all volcanoes are present in all boundaries
2.
– Volcanoes seem to occur mostly at the plate boundary in a linear way following the boundary itself
3.
– I found 5 unique plate boundaries. V1 between the Pacific and North American Plate, V2 between the Nazca and South American Plate, V3 at the…[Read more]

1a) No, all volcanoes are not present on all boundaries.

1b) Volcanoes that occur near or at a plate boundary are distributed in a linear pattern. There are many volcanoes occurring in a small area, therefore, the dots look like lines. Although there are a lot of volcanoes in a small area, they are spread out all throughout the map. There is no…[Read more]

1a. No, they are present at all but not all of the boundaries. 

1b. They are more densely concentrated along some boundaries and occur in linear or curved patterns. At the boundaries where the volcano distribution is most concentrated and linear, the volcanoes occur on top of the boundary. The volcanoes that are more spread out from each…[Read more]

1A) Yes, although there may be very few, it seems to be that there is at least one or two volcanoes present at some point along every plate boundary.

1B) Volcanoes seem to be much more frequent and densely packed along the ocean-continental plate boundaries. Typically occurring on the continental side of the boundary in a mostly linear fashion…[Read more]

I thought my house was in pretty good shape since my dad is always making sure everything is fixed but apparently that wasn’t the case. As I was walking around I stepped on some water by the radiator and realized that there were small droplets off water coming from it. At that moment I wondered why this was the case since we recently changed the c…[Read more]

Windsor, I completely agree with your conclusion based on your observations. You stated that once you replaced the flapper valve, the flushing noise and the dripping noise stopped at random times. This makes it convincing that the flapper valve was faulty and was causing the noises.

Although I agree with your conclusion, in your hypothesis you…[Read more]

I agree that your hypothesis is not conclusive and might need some further experimentation. In your experiment, you stated that your mom’s food started to change in taste and smell when you put it in the middle rack. This was convincing that the temperature of the fridge plays a role in the freshness of the food. Further,  you put ginger paste in…[Read more]

Windsor, based on your observations and the lack of flushing noises after changing the flapper valve, I agree that your hypothesis is supported by your observations. The effect of changing the flapper valve is the most compelling evidence supporting your claim because the immediate result of this action was the end of the sound, meaning it was…[Read more]

Afrina, based on the additional observation about the hypothesis, I would agree that it is partially but not completely supported by the results of your experiment. Ginger paste and the temperature of the refrigerator are both variables that affect the shelf life of the food, but temperature can also affect how much ginger paste is required. It…[Read more]

In the last few days, I have observed a lot of things but there was one thing that made me wonder why that is happening. I am allergic to a lot of food, so I cook for myself separately. I observed that the food I cooked for myself cannot be eaten after 1 day, they smell and tastes bad but on the other hand, the food my mom is cooking for my other…[Read more]

Natalia, based on your observations and the results of your experiment I have to agree that your hypothesis of the sunlight evaporating the water out of the soil in the plant near the window was not supported by the results of your experiment.  I find the evidence of moist soil being present in the plant pot that was relocated away from the…[Read more]

Tajria, based on your observations and the results of your experiment I definitely agree with your conclusion that both the exposure to sunlight throughout the day and the significantly less obstructed heater at night are causing your room to be warmer than your cousins. The portion of your experiment when you placed blankets on top of your…[Read more]

Last week I forgot to water the pothos plants that were placed around my house and was worried that the soil had dried out and the plants would die, because I had already been watering them inconsistently for the past month. When I went to water them earlier this week I noticed that the leaves of the plants by the windows were drooping and…[Read more]

I live in a four family house and my room is mirrored next to my cousin’s room. I live on the right side of the second floor and she lives on the left side of the second floor. I observed that my room is always warmer than her room, even though we have central heating (long strip heaters attached to the base of the wall) and our rooms have the s…[Read more]
