Changing Earth’s Surface. Weathering Erosion and Deposition Weathering The process that breaks down rock and other substances at Earth’s surface.

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
