Private Notes
The first of five daily science lectures which are intended to be of particular interest to children.
Dr James Jackson, a geologist from Cambridge University, looks for clues in what explorers, meteorites, volcanoes and earthquakes tell us about the make-up of Planet Earth.
Dr James Jackson reveals that the key to understanding how the Earth moves lies not above the sea but deep in the oceans.
Dr James Jackson investigates how solid rock is turned to molten lava and explains how volcanoes are a planet's way of keeping cool. The lectures continue tomorrow and Sunday.
Dr James Jackson draws on evidence from sunken cities and sea shells found high in mountain ranges to explain what happens when continents stretch and collide.
In his final lecture, Dr James Jackson describes how water has affected the history of Earth and looks at the moon, Venus and Mars to imagine what life would be like without it.
