Scientists are seeing ice age beginnings for very first time
Some fantastic 3D images have emerged from the bottom of the North Sea, making it possible to document the beginning of the ice ages 2.6 million years ago.
Among their findings is that ice age cycles suddenly became stronger just over 600,000 years ago. Researchers were also struck by how little plant life has changed over the past 1.7 million years.
A stone stemming from magma can be designated as igneous, but it could also be called spotted. A child might find learning geology as hard as a rock – given even a fraction of its formal terminology – or easy as pie if a few ordinary concepts are applied.
