What occurs during the Winter and Summer that makes the day or night longer? What causes this to occur?

the sun's rays hit the Earth at a shallow angle because the sun is lower in the sky.The long nights and short days prevent the Earth from warming up.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
