Comments from Sharky (The Sand)


So you have already gathered and analysed the data referring to the sand! 
Let's have a look....

Ins Puigcargol I just hope that all the sand is from the same beach. Remember that when doing research it is very important to know where the data comes from! Sorry to hear that you were not able to have a look at your coastal area with Google Earth's imagery, right now I do not know of any other source of aerial or satellite images.

Ok, now let's relate the granulometry with the height and diameter of your heap of sand. Does finer sand make taller or flatter heaps? Do you think that wind and waves will move the sand in different ways depending on the size of the grains?
You have not observed differences in the inclination of the slope of the beach face. But thinking on your results of the experiment, which beach do you think will have a steeper slope?

I see that the main factor that brings sand to the beach is rivers. But IES Tres Turons 1A says that the port prevents the arrival of sand from the Tordera River which is further north. What process brings the sand from the Tordera to Picòrdia beach of Arenys de Mar?

If you get the answer to the last question, you will also be answering the questions of the water!!!
Come on, think about it. All students from all the schools can suggest an answer!

Looking forward to your comments!!!!
