Sunny Day Flooding Division B Science Olympiad Elimination

What causes tides in the ocean?

• Wind patterns

• Gravitational forces of the Moon and the Sun

• Ocean currents

• Underwater volcanoes

How does sea level rise impact coastal communities?

• Sea level rise reduces the risk of natural disasters in coastal communities

• Sea level rise leads to increased agricultural productivity in coastal communities

• Sea level rise can lead to flooding, erosion, saltwater intrusion, and increased vulnerability to storms.

• Sea level rise has no impact on coastal communities

What are some examples of coastal infrastructure?

• Desalination plant, wastewater treatment facility, power plant

• Highway, bridge, tunnel

• Pier, marina, lighthouse

• Seawalls, breakwaters, groins, jetties, beach nourishment projects

What is sunny day flooding and how is it related to sea level rise?

• Sunny day flooding is flooding that occurs during high tides on sunny days, and it is related to sea level rise caused by climate change.

• Sunny day flooding is unrelated to sea level rise

• Sunny day flooding is caused by heavy rainfall on cloudy days

• Sunny day flooding is a result of excessive groundwater extraction

What are king tides and when do they typically occur?

• King tides are the highest tides that occur when the gravitational pull of the sun and moon are aligned. They typically occur during a full moon or new moon.

• King tides are only visible in the Southern Hemisphere

• King tides occur randomly throughout the year

• King tides are caused by volcanic eruptions

Explain the concept of spring tides.

• Spring tides are the exceptionally high and low tides that occur during the full moon and new moon phases.

• Spring tides happen when the Earth is farthest from the Sun.

• Spring tides occur only during the winter season.

• Spring tides are caused by the gravitational pull of Mars.

How can coastal communities adapt to sea level rise?

• Planting more trees inland

• Encouraging more beachfront development

• Implementing strategies such as building sea walls, restoring wetlands, creating elevated structures, implementing zoning regulations, and investing in early warning systems.

• Ignoring the issue and hoping for the best

What are the main factors contributing to sunny day flooding?

• Urban development, deforestation, and agricultural practices.

• Wind patterns, ocean currents, and lunar cycles.

• Volcanic activity, asteroid impacts, and solar flares.

• Sea-level rise, land subsidence, and climate change-induced extreme weather events.

Why is it important to protect coastal infrastructure?

• To attract more tourists to the area

• To prevent damage from natural disasters and ensure the safety and stability of coastal communities.

• To increase property values along the coast

• To provide a habitat for marine life

How do tides affect marine ecosystems?

• Tides cause an increase in biodiversity in marine ecosystems

• Tides impact marine ecosystems through changes in water movement, nutrient distribution, habitat availability, and species behavior.

• Tides lead to a decrease in water salinity in marine ecosystems

• Tides have no impact on marine ecosystems
