CURRICULUM TOOL: CHANGING THE EARTH’S SURFACE

WEATHERING, EROSION, & DEPOSITION

High School of Language and Innovation 2012 (draft)

NYS Earth Science Core Curriculum

Performance Indicator 2.1

Use the concepts of density and heat
energy to explain observations
of weather patterns, seasonal changes, and the movements of Earth’s plates.

2.1s Weathering is the physical and chemical breakdown of rocks at or near Earth’s surface.
Soils are the result of weathering and biological activit
y over long periods of time.

2.1t Natural agents of erosion, generally driven by gravity, remove, transport, and deposit
weathered rock particles. Each agent of erosion produces distinctive changes in the material
that it transports and creates characteris
tic surface features and landscapes. In certain
erosional situations, loss of property, personal injury, and loss of life can be reduced by
effective emergency preparedness.

2.1u The natural agents of erosion include:

• Streams (running water): Gradient,
discharge, and channel shape influence a stream’s velocity
and the erosion and deposition of sediments. Sediments transported by streams tend to
become rounded as a result of abrasion.

Stream features include V
-
shaped valleys, deltas,
flood plains, and
meanders.

A watershed is the area drained by a steam and its tributaries.

• Glaciers (moving ice): Glacial erosional processes include the formation of U
-
shaped valleys,
parallel scratches, and grooves in bedrock. Glacial features include moraines, drumli
ns, kettle
lakes, finger lakes, and outwash plains.

• Wave Action: Erosion and deposition cause changes in shoreline features,

including beaches, sandbars, and barrier islands. Wave action
rounds sediments as a result of
abrasion. Waves approaching a shoreline move sand parallel to the shore within the zone of
breaking waves.

• Wind: Erosion of sediments by wind is most common in arid climates and along shorelines.
Wind
-
generated features in
clude dunes and sand
-
blasted bedrock.

• Mass Movement: Earth materials move downslope under the influence of gravity.

2.1v Patterns of deposition result from a loss of energy within the transporting

systems and
are influence by the size, shape, and density

of the transported particles. Sediment
deposits may be sorted or unsorted.


2.1w Sediments of inorganic and organic origin often accumulate in depositional

environments. Sedimentary rocks form when sediments are compacted and/or

cemented
after burial or a
s the result of chemical precipitation from seawater.
