Subduction occurs between two colliding tectonic plates
Different perceptions of a region can make that region less defined is true im not a 100% sure tho
False. Deserts do not expand linearly or in mappable patterns due to the changing nature of weather patterns. Deserts are formed through the process of erosion which breaks down into sand particles over time, through wind action for example, as the wind carries sand particles, this shifts the shape and form of sand dunes and deserts over time.
