L1 Geoengineering

What is a primary responsibility of coastal engineers?

• Designing offshore oil rigs.

• Protecting coastal communities and ecosystems.

• Developing deep-sea exploration vehicles.

• Managing international shipping routes.

How does climate change affect coastal communities?

• It leads to decreased storm intensity.

• It causes sea levels to rise and storms to become more intense.

• It stabilizes coastal ecosystems.

• It reduces the need for coastal engineering.

Which of the following is an example of a hard engineering method used for coastal protection?

• Beach nourishment.

• Restoring wetlands.

• Building seawalls.

• Planting mangroves.

What is a key characteristic of soft engineering methods for coastal protection?

• They involve constructing robust, permanent barriers.

• They directly resist the forces of the sea.

• They work in harmony with natural processes.

• They are typically made of concrete or steel.

What are the primary factors contributing to sea level rise?

• Volcanic eruptions and tsunamis.

• Melting glaciers and thermal expansion of seawater.

• Increased rainfall and river discharge.

• Ocean currents and tidal forces.

What are some of the immediate threats posed by rising sea levels to coastal communities?

• Decreased biodiversity and colder ocean temperatures.

• Increased flooding, erosion, and saltwater intrusion.

• Stronger ocean currents and more frequent hurricanes.

• Reduced fishing yields and deeper harbors.

What are the three main approaches coastal engineers use to address the challenges of sea level rise?

• Mitigation, Adaptation, and Restoration.

• Accommodation, Protection, and Retreat.

• Prevention, Containment, and Relocation.

• Fortification, Preservation, and Development.

What is a key responsibility of coastal engineers concerning ports and harbors?

• Managing global trade routes and shipping logistics.

• Designing, constructing, and maintaining port infrastructure.

• Regulating international maritime laws and policies.

• Operating cargo cranes and managing port personnel.
