64 pages, 180 x 128 mm Our planet’s surface bears the giant
scars of an asteroid or comet impact history stretching back
more than 2 billion years. In Australia there are 36 structures
ranging from tens of metres to tens of kilometres in diameter,
and recognised to varying degrees of certainty as having been
formed by giant meteorite impact. In clear and concise language
this book begins with ancient beliefs and myths about craters
and then explains how they are actually formed and provides
details of their structure. Using the record in the rocks, the
authors also assess the likelihood of future impacts and their
possible effects.
