WILL GIVEEE BRAINLIES Why do scientific laws and theories change over time?

Your question has been heard loud and clear.

Well by the nature of science itself , we know that it is a rapidly progressing area . So , scientific laws are basically ideas from theories , it does not mean that it is absolute , because future research of that same topic on which the law is based , can always change and thus the theory and thus the law. So , scientific laws and theories change over time due to new phenomena and scientifc research that gives a more accurate theory than the old laws and theories.

Thank you

glacial erosion, the picking up and movement of earth beneath a glacier, is also referred to as plucking. erosion and transportation of individual pieces of bedrock, especially large "joint block occur as a result of this glacial erosion. plucking is type of erosion in which rocks become frozen into the bottom and sides of the glacier.as the glacier moves downhill it 'plucks' the rocks frozen into the glacier from the ground.
