Changing Earth’s Surface
Weathering Erosion and Deposition
WeatheringThe process that breaks
down rock and other
substances at Earth’s surface
Erosion The removal of rock
particles by wind, water,
ice, or gravity
Weathering Erosion and Deposition
Erosion
The process by which natural
forces move weathered
rock and soil from one place to another
Weathering Erosion and Deposition
Sediment
The material moved by erosion
Weathering Erosion and Deposition
Sediment May be pieces of
rock, soil, or the remains of plants and
animals
Weathering Erosion and Deposition
DepositionWhen wind and water
finally calm, the rocks and the
sediment settle to the
bottom
Weathering Erosion and Deposition
Deposition
Changes the shape of the
land
Weathering Erosion and Deposition
Act together in a cycle that wears down and builds up
Earth’s surface
Weathering Erosion and Deposition
The force that moves
rock and other
material downhill
Weathering Erosion and Deposition
Gravity
Any of several
processes that move sediment downhill
Weathering Erosion and Deposition
Mass Movement
Landslides, Mudflows,
Slump, Creep
Weathering Erosion and Deposition
Types of Mass Movement
Most destructive mass movement
Types of Mass Movement
Landslide
Rock and soil slide quickly down a steep
slope
Rapid downhill
movement of water, rock,
and soil
Types of Mass Movement
Mudflow
Types of Mass Movement
Slump
A mass of rock and soil
suddenly slips down a slope in one large
mass
Types of Mass Movement
Creep
Very slow downhill
movement of rock and soil
