Sea Level Rise

The video tutorial explains the air-sea interface and its role in defining sea level. It discusses short and long-term factors affecting sea level changes, such as wind conditions, atmospheric pressure, and climate change. The concept of mean sea level is defined, and rising sea level trends are explored, highlighting the impact on coastal areas, including increased flooding and risk in places like Galveston, TX. The tutorial concludes by examining the causes of global sea level rise, primarily due to global warming, melting ice sheets, and seawater expansion.

What is the air-sea interface primarily responsible for?

• Determining wind conditions

• Measuring atmospheric pressure

• Supporting marine life

• Defining land elevations

What is the mean sea level?

• The sea level during a storm

• The lowest point of the tide

• The average sea surface height over time

• The highest point of the tide

How has the frequency of high tide flooding changed over the past 50 years?

• It has increased by 300% to 900%

• It has remained the same

• It has decreased by 50%

• It has doubled

Which location is experiencing one of the fastest sea level rises?

• New York, NY

• Los Angeles, CA

• Galveston, TX

• Miami, FL

What are the two main contributors to global sea level rise?

• Increased rainfall and river flow

• Deforestation and urbanization

• Melting ice sheets and thermal expansion

• Volcanic activity and earthquakes
