Changing
Earth’s Surface
Lesson 3 Vocabulary
Vocabulary
 Weathering:
the mechanical and
chemical process that changes Earth’s
surface over time
 Physical vs Chemical Weathering:
 Physical: process of breaking down rock
without changing the composition
 Chemical Weathering: The process that
changes the composition of rocks
 Sediment: The material formed from rocks
broken down by weathering
Vocabulary Cont….
 Erosion:
the moving of weathered
material or sediment from one location to
another
 Deposition: the laying down or settling of
eroded material
 Mass Wasting: the downhill movement of
a large mass of rock or soil due to gravity
 Glacier: Large masses of ice formed by
snow accumulation on land that moves
slowly across the earth’s surface
