Continental drift plate tectonics theory. In particular, the English geologist Arthur Holmes proposed in 1920 that plate junctions might lie beneath the sea, and in 1928 that convection currents within the mantle might be the driving force. Holmes' views were particularly influential: in his bestselling textbook, "Principles of Physical Geology," he included a chapter on continental drift, proposing that Earth's mantle contained convection cells which dissipated radioactive heat and moved the crust at the surface. Holmes' proposal resolved the phase disequilibrium objection (the underlying fluid was kept from solidifying by radioactive heating from the core). However, scientific communication in the '30 and
Ice Age: Continental Drift are some visually inventive high points." Simon Brew, writing for Den of Geek, gave a very positive four-star review, saying that "not only is "Ice Age 4" arguably the best in the franchise yet, it's also, a little surprisingly perhaps (given that it's a fourth movie in a franchise, turned around on a strict cycle), turned out to be thoroughly, thoroughly entertaining family blockbuster." "Ice Age Village" is a mobile video game, developed by Gameloft, and was released on April 5, 2012 to iPhone, iPad and various Android devices.
