Year 5 travelled on two coaches to Lulworth. We visited the village of Lulworth and were shown round by a guide. The guide pointed out the Triassic, Jurassic and Cretaceous rocks and fossils around the village and explained how the stones were formed. We learnt that chalk is a very strong sediment rock and can filter water; if you pour dirty water over chalk, the impurities will be removed.
We walked from Lulworth to Durdle Door which was pretty tiring as it was quite hilly; there were 44 steps up the hill and 144 to walk down to Durdle Door. Erosion is caused by water and other stones bashing against the land. It starts as a crack then turns into a cave, next into an arch and finally into a stack. This is how Durdle Door was formed.
We earned an ice-cream after the long walk! We had our lunch at Durdle Door and came back to school in the afternoon.
On our walk we bumped into some Year 10s from another school who were struggling to get up the hill. We overtook them on the way down!
