You decide to farm oil palms in a rain forest climate. What strategy would most help minimize the environmental costs?(1 point)
Responses
A. adjusting the application of fertilizer to the specific nutrient needs of oil palms
B. moving wildlife away from the cultivated land for protection
C. dedicating a large area to the unique cultivation of oil palms
D. planting trees on land that has previously been cleared of trees
A. adjusting the application of fertilizer to the specific nutrient needs of oil palms
This strategy would help minimize the environmental costs by reducing the amount of excess fertilizer that can run off into waterways and harm the surrounding ecosystem. By only applying the necessary nutrients needed by the oil palms, you can prevent pollution and minimize the environmental impact on the rain forest climate.
What effect can erosion have on a beach?(1 point)
Responses
A. It can cause lower beach elevations.
B. It can cause wider beaches.
C. It can cause an increase in sand on beaches.
D. It can cause higher beach elevations.
A. It can cause lower beach elevations.
Erosion can gradually remove sand and other materials from a beach, leading to lower beach elevations over time. This can impact the width and size of the beach as well as its overall appearance and function.
Which is NOT considered a cause of beach erosion?(1 point)
Responses
A. Human activity like building too close to the shoreline & damaging sand dunes
B. Wave action, the continuous movement of seawater
C. Beach renourishment strategies like building up sand dunes and supporting them with fencing
D. Storm waves can move sand deeper into the water, creating sand bars
C. Beach renourishment strategies like building up sand dunes and supporting them with fencing
Beach renourishment strategies are actually implemented to combat beach erosion, not cause it. The other options listed are all causes of beach erosion.
Identify the shoreline erosion management STRUCTURE that has the following positive aspects: biodegradeable, but remains in place long enough to encourage seagrass rooting and allows plant
A. Jetties
B. Sea Walls
C. Beach Nourishment
D. Coconut Coir Log Walls
D. Coconut Coir Log Walls
Coconut Coir Log Walls are a biodegradable erosion management structure that can help encourage seagrass rooting and allow plant growth. They provide stabilization and erosion control benefits while being environmentally friendly.
While Beach Renourishment is effective, the following are negative EXCEPT side effects(1 point)
Responses
A. Expensive process
B. Beach is elevated & extended
C. Beaches must close during renourishment
D. Results are temporary & must be repeated every 5-7 years
B. Beach is elevated & extended
This is not a negative side effect of beach renourishment. In fact, an elevated and extended beach is typically a desired outcome of the renourishment process. The other options listed are negative side effects of beach renourishment.
