And, despite the fact that the ocean absorbs more than 90% of the heat caused by global warming, until 2020, there had been little evidence that these currents were changing. The simplified map in Fig. As we have seen, winds blow from areas of high atmospheric pressure to regions of low atmospheric pressure. Paul Voosen is a staff writer who covers Earth and planetary science. Surface winds, waves, and currents mix and distribute the heat throughout this layer therefore the depth of the mixed layer can change with the seasons. Ocean currents are similar to winds in the atmosphere in that they transfer significant amounts of heat from Earth's equatorial areas to the poles and thus play important roles in . F=[1347],G=[2105], find each of the following, if it exists.\.
