The world's ocean is heated at the surface by the sun, and this heating is uneven for many reasons. Earth's rotation, revolution around the sun, and tilt all play a role, as do the wind-driven ocean surface currents.This animation shows the long-term average sea surface temperature, with red and yellow depicting warmer waters and blue depicting colder waters.
The Earth's system exemplifies stability and change. Change and rates of change can be observed and quantified over very short or long periods of time and various spatial scales (e.g., from landscape level to global processes).
This NASA visualization shows sea surface salinity observations (September 2011-September 2014). Students review the video and answer questions.
Students will investigate the differences in sea surface height during an El Niño event by creating a model with gelatin, sherbet and whipped creme.
Students will read an article and/or watch a video clip about the effects of El Niño. They will then answer questions about the phenomenon and its effects on global health.
Students will use coloring sheets to create a color coded model of El Niño. If the Data Literacy Map Cube is used with this, students should color their models first.
