Which statement describes the approximate average trend of surface ocean heat content during this time period? An increase of about 140 x 1021 joules

An increase of about 20 x 1021 joules

A decrease of about 60 x 1021 joules

A decrease of about 80 x 1021 joules

heat a spark and oxygen

sand 60

clay 10

silt 30
