Matter ~ Anything that has mass and occupies space. Mass ~ A measurement of the amount of matter in an object. Weight ~ A measurement of the gravitational force acting on an object. Physical changes ~ Changes matter undergoes without changing composition. Physical properties ~ Properties of matter that can be observed or measured without trying to change the composition of the matter being studied. Chemical changes ~ Changes matter undergoes that involve changes in composition...

NREM 301 Exam 1 Questions and Answers Graded A+ What is the difference between physical and chemical weathering? Physical weathering breaks down rocks into smaller pieces without changing their chemical composition, while chemical weathering involves changes to the minerals in the rock due to reactions with water, air, or other chemicals. How does frost wedging contribute to physical weathering? Frost wedging occurs when water enters cracks in rocks, freezes, expands, and breaks the...
