2.3 - Weathering, Erosion, and Sedimentation

The wearing down or breaking of rocks through physical, chemical or organic means.

• Erosion

• deposition

• weathering

• mixing

a natural process where material is worn away from the Earth's surface and transported elsewhere

• Erosion

• sedimentation

• weathering

• mixing

Select the examples of weathering (all that apply)

• Composition of rocks changes through exposure to water or oxygen

• Water freezing/ expanding within cracks of rocks

• Glaciers move sediments over time

• moving water picks up sediments and carries them to new locations

Select the examples of erosion (all that apply)

• Wave action breaks rocks apart

• wind picks up small pieces and sand and transports them down the beach.

• Gravity causes rocks to break off and move to a new location

• kelp releases sulfuric acid that breaks down rocks

fine silt is most likely to settle to the bottom under which conditions

• high current flow

• medium current flow

• low current flow

Which of the following particle sizes would most likely settle to the bottom with high current speeds.

• gravel

• course sand

• fine sand

• silt

Rocky shores are characterized by

• high rate of sedimentation

• low rate of sedimentation

shoreline characterized by little ro no water movement, little or no slope, and sedimentation is the primary factor in formation.

• Rocky Shores

• Sandy shores

• muddy shores

• Volcanic shores

Select the characteristics that apply to the shoreline in this picture. (select all that apply)

• River Delta

• Water speed does not allow for sedimentation.

• Water slows as it reaches the ocean

• as water speed slows, sedimentation occurs, forming sandbars and land masses

Which of the following sediments are formed from erosional processes acting on continental rocks.

• Biogenous sediments

• Hydrogenous sediments

• Lithogenous sediments
