Total questions: 10
Worksheet time: 13mins
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
