Question

Sea level is expected to rise because of warmer climate due to the following:

• A. oceans expand as they get warmer
• B. glaciers and ice-sheets melt
• C. Both a and b
• D. None of the above

Answer 1

The correct option is C Both a and b

Sea level rise is one of the major problems facing our planet in the 21st century. It is attributed both to the thermal expansion of oceans due to increased temperature because of global warming and also to melting of ice sheets and glaciers on land. Melting of ice shelves and icebergs in oceans also contributes to sea level rise.
