TY - JOUR T1 - Physical Processes in Nature – The Water 3. Physics of Lakes A1 - Sós, Katalin A1 - Bartyik, Tamás A1 - Nánai, László JA - Obzory matematiky, fyziky a informatiky Y1 - 2018 VL - 47 IS - 3 SP - 25 EP - 34 SN - 1335-4981 N2 - Our article series titled “Physical processes in Nature”, launched in 2014 had covered our goal to provide concrete help to educators with an integrated approach to natural science education. In the series we gather phenomena and processes showing the real coupling in physics, biology, chemistry and geography, the uniform approach to living environment. In the first article of the series we deal with soil physics, in the second with the physical and chemical characteristics of the oceans and seas, the third article was devoted to problem of oceans and seas, collecting their physical properties, their changes and reasons of changes attributed. In this article we collect the physical characteristics of the lakes and the causes of this characteristic’s changes. ER -
