The Gauteng Department of Education (GDE) is inviting retired teachers and principals to a seminar this week in Midrand to see how it could use them to help in classrooms or in the general running of schools.
Antarctica is the coldest, windiest and driest place on Earth. It is almost entirely covered in ice. The lowest temperature measured was -88ºC. In the interior, wind speeds reach up to 350 km/h. The annual rainfall is about 50mm inland and 35mm along the coast (South Africa's average annual rainfall is 464mm, and the world average is 857mm). During summer, Antarctica has 24-hour days and no nights, whereas in winter, there are 24-hour nights and the sun never rises for about one month.
