Anytime you see bold and underlined words, you will need to write those down

EROSION the transport of sediment Energy increases Water Gravity Ice Wind EROSION the transport of sediment Energy increases More energy = more particles and bigger particles

DEPOSITION Sediment is dropped Energy decreases Wind Water Gravity Ice

Which will drop faster? vs. Which of the following will settle faster? Bigger/smaller Rounder/flatter Denser/less dense

All the same size or graded, due to change in energy Sorted Unsorted All the same size or graded, due to change in energy Fall randomly, mixed

Graded bedding

EROSIONAL-DEPOSITIONAL SYSTEMS Glaciers Shorelines Rivers Deserts

Dynamic Equilibrium Erosion in one place = Deposition someplace else Head of river = Mouth of river Pitted bedrock = Sand dune Gouged bedrock = Moraine deposit

GRAVITY EROSION and DEPOSITION

Mass movement Any form of giant slabs of land moving all at once

Landslides 1 2

Gravity pulls big chunks of rock off of a cliff Rock fall 1 2 Gravity pulls big chunks of rock off of a cliff

Creep The slow movement of giant areas of land – indicated by bent tree trunks, leaning poles, cracked roads

When land sinks into a cave under the surface Subsidence When land sinks into a cave under the surface

Slump A slab of loose land is pulled down and leaves a concave scare on the cliff face

Alluvial fan Fan-shaped deposit of angular, unsorted sediment at the base of a cliff or hill

Talus Any gravity-deposited sediment
