Controlling Constructive and Destructive Processes EQ How can
constructive and destructive processes be controlled through the
use of technology? How does technology affect constructive and
destructive processes? What are examples of technology used to
control constructive and destructive processes?
Slide 26
Effects on Constructive Processes Dam a structure built across
a river to control its flow Positive Effect Flood Control
Hydroelectric Power Negative Effect Holds back sediment Prevents
deposition of flood plains, deltas, and beaches
Slide 27
Effects on Destructive Processes Prevention of beach erosion
Groin a structure built perpendicular to the beach. Positive Effect
Traps sand that moves along the shore and causing the beach to
build up. Negative Effect Beach Erosion down stream is worse.
Seawall a structure built parallel to the shore Positive Effect
Protects land behind if from ocean the ocean waves Negative Effect
Ocean side beach will erode Beach Nourishment sand from ocean or
nearby rivers are pumped onto the beach
Slide 28
Effects on Destructive Processes Prevention of beach erosion
(cont) Seawall a structure built parallel to the shore Positive
Effect Protects land behind if from ocean the ocean waves Negative
Effect Ocean side beach will erode Beach Nourishment sand from
ocean or nearby rivers are pumped onto the beach
Slide 29
Effects on Destructive Processes Prevention of soil erosion
Contour Plowing method in which farmers plow across the sided of
hill instead of down Terracing the planting of corps on terraces
(steps) built into steep hillsides. Windbreaks rows of plants or
fences. Slow down wind and limit the distance it can carry soil.
Vegetation used to hold soil in place Storm drain management a
system of drains Prevents flooding and soil erosion
Slide 30
Effects of Volcanoes and Earthquakes Volcanoes and Earthquakes
can not be controlled; However scientist have ways to determine
when and where these they might occur. Volcanoes instruments are
used to detect changes in volcanoes Earthquakes Detailed maps show
major faults Safety Education No new buildings on or near faults
