1. What could be some factors caused extreme weather?:When the storm or flood comes from the extreme weather then the sea, river, ocean or lake will rise and become an even taller then the water before and it would become a flood.
2. Could you related it to the water cycle?:The glacier would melt and come back down to the ocean then if the ocean has more water, the water would evaporate into the rain and then lots of rain would fall down and then it would restart the water cycle again.
