The formation of sea ice around Antarctica plays a critical role in maintaining Earth's temperature.Is this true or false?TrueFalse

While researching a topic, a student has taken the following notes:In 2022 Dr. Peter Fretwell and a team of scientists studied the loss of sea ice in an Antarctic region and how that loss impacted emperor penguins’ breeding patterns.They recorded a 100% loss of sea ice in the area west of the Antarctic Peninsula.This loss had wide-reaching impacts on whether or not chicks from the nearby emperor penguin colonies would survive.In 2022, there was 100% loss of sea ice in the area and the chicks had a 20% survival rate.In 2018, there was a 40% loss of sea ice in the area and the chicks had a 70% survival rate.The student wants to summarize the study. Which choice most effectively uses relevant information from the notes to accomplish this goal?For a 2022 study, Dr. Peter Fretwell and a team of scientists measured birth rates of emperor penguins in the Antarctic Peninsula.eliminateDr. Peter Fretwell and his team’s 2022 study of emperor penguins’ breeding patterns as impacted by sea ice rates showed that as the sea ice loss increased, the chicks’ survival rates decreased.eliminateKnowing that the emperor penguin species was in danger, Dr. Peter Fretwell and his team took measurements of the loss of sea ice in the Antarctic Peninsula to find how it affected penguin breeding patterns.eliminateDr. Peter Fretwell and his team set out to determine the relationship between the amount of sea ice and the survival rate of the chicks.

Which of these should not be included in a summary of this article?A.Kim Holmen is the head of research for the Norwegian Polar Institute.B.The NPI found that the temperatures in the Southern Ocean are rising rapidly.C.Warming temperatures bring increased melting of glaciers in Antarctica.D.Scientists used elephant seals to monitor climate change near Antarctica.SUBMITExtras

The Ross Ice Shelf in Antarctica is important to ocean circulation because:Question 30Select one:it keeps the glaciers from floating into the sea, thus keeping sea level rise to a minimumstrong storms that drive surface circulation begin at its edge in the Southern Oceanit is home to most of the world's penguins (and they're cute)it is where dense, cold water forms which is important to THCClear my choice

During the last few decades, accumulated ice in Antarctica has:Question 11Select one:increased everywhereincreased in some places and decreased in othersdecreased everywherenot changed much at all
