Drag the triangle to the MINUS side of the temperature gauge to decrease the air temp.What happens when the air temperature falls? (CHOOSE ALL THAT APPLY) The salinity levels fall (becomes less salty) The deep ocean current speeds up Salinity levels rise (becomes more salty) The sea ice melts There is more sea ice The deep ocean current slows down

## Step 1<br />The problem is about the effects of decreasing air temperature on the ocean's salinity and currents. The air temperature and the ocean's salinity are closely related. When the air temperature decreases, the sea ice melts, which increases the salinity of the ocean.<br /><br />## Step 2<br />The melting of sea ice increases the salinity of the ocean because the ice is freshwater, and when it melts, it adds freshwater to the ocean, which increases the salinity.<br /><br />## Step 3<br />The increased salinity of the ocean affects the deep ocean currents. The deep ocean currents are driven by differences in salinity and temperature. When the salinity increases, the water becomes denser, which increases the speed of the deep ocean currents.<br /><br />## Step 4<br />The increased salinity and the increased speed of the deep ocean currents have a significant impact on the global climate. The deep ocean currents carry heat from the equator to the poles, which helps to regulate the Earth's climate.
