Difference Between Physical And Chemical Change With

Physical Change: Chemical Change: When a substance undergoes a physical change, its composition remains the same despite its molecules being rearranged. When a substance undergoes a chemical change, its molecular composition is changed entirely. Thus, chemical changes involve the formation of new substances. Physical change is a temporary change.

Metamorphic Rock Physical Geography

Metamorphic rocks may change so much that they may not resemble the original rock. Any type of rock—igneous, sedimentary, or metamorphic—can become a metamorphic rock. All that is needed is enough heat and/or pressure to alter the existing rock’s physical or chemical makeup without melting the rock

Physical Weathering Examples - Softschools

Physical weathering is a naturally or artificially occurring geological phenomenon in which rocks change their physical properties without affecting their chemical composition. Basically, the rocks are still made up of the same types of rocks and contain the same minerals they once did, they are just no longer in the same size or shape as before.
