Drag each label to the correct location on the image. The graph shows how sea ice extent in the Arctic region has changed since 1975. Classify the questions based on whether they can or cannot be answered using the graph. What is the overall change in sea ice extent since 1980? How has the change in sea ice extent affected precipitation? Which regions have been most affected by reduced sea ice extent? In which year was sea ice extent the highest? How has sea ice extent fluctuated every five years since 1980? What is the estimated sea ice extent in 2020?

1. A decline in Ice Cover

2. The Earth's climate is a complex interconnected system. Thus, it is difficult to determine the exact causes for the ice melt in the Arctic Ocean.

3. ocean salinity will decrease

There has been a consistent decline in the overall extent of the ice surface, with roughly a third less ice observed since 1978.

Understanding the rapid melting of sea ice in the Arctic Ocean is challenging due to the Earth's intricate and interconnected climate system, making it difficult to pinpoint specific causes.

So, The primary composition of the ice in the Arctic Ocean is freshwater. Consequently, if the entirety of this ice were to melt, it would lead to a substantial decrease in ocean salinity, thereby influencing global ocean currents.
