In today’s lesson we did 2 prac’ s on how the tectonics plates move and make mountains and it was a excellent prac.
After working on this activity I have noticed and understood the ways in which this activity relates to mid-ocean ridges. The thing that I have understood is that mid ocean ridges is the area where most activity occurs within ocean sea bed. It also produces rocks through lava(which comes from the convection currents). Though what I have noticed about the spreading is that when the plates separate they rise up and then lengthen down, this then pushes the lava further away or closer to the ridge to then cause the rocks to be younger or older. I noticed with the paper emerging it rose up to a certain point and then extended as we pushed up. I know this means that the paper was closer to the ridge, was higher and further away and lower. The strip that I coloured that resembled the oldest rock was the colour closest to the trench which was further away from the ridge. The youngest rock was the one closest to the ridge as they come after the older ones and push them away. The first strip to be swallowed is the one that is closest to the trench in this case the further one, simply because it is closer and due to continual plate separation they will be pushed to the trench.
