A model scientific is a simple representation of a more complex system.

Explanation:

The scientific model is a simplified representation of scientific systems that are more complex or impossible to see by the human eye, such as an atom or a solar system. Although this representation is simplified, it has the responsibility to produce all the essence, content and behavior of the original systems, thus allowing the models to be used in scientific studies and research and to promote concrete results that provide accurate information about the original systems.

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.
