The Atacama Desert forms one of the major hyper-arid deserts of the world and it is known to be the driest place on Earth. The extreme aridity of the climate and unusual mineralogy of the regolith in the Atacama region is of considerable interest because of its value as an analogue to the Martian surface. The sedimentary succession in the Atacama Desert records deposition under an arid to semiarid climate from the late Jurassic (150Ma) to the present day (Hartley‚ 2005). Comparison with other long-lived

The Evolution of Life This section provides information about the evolution of life on Earth. For reasons of simplicity some important events and life forms were selected for each geological time span. However this should not give the impression that the evolution of life on Earth is or was a sequential event. Many life forms that were not mentioned in this text were very successful and have evolved or in some cases maintained a very successful life strategy. Prokaryotes‚ for example are the most

Dinosaurs and Man may have Co-existed It has been a constant debate between creationists and evolutionists on how old the world is. Evolutionists believe that earth was created over 4.5 billion years ago while‚ creationists believe in a young earth created only about 6‚000 years old. With that debate is the argument on when the dinosaurs walked the earth. Evolutionism teaches that humans and dinosaurs lived millions of years apart from each other. What many people are not aware of is that there

In Walter Alvarez’s article‚ “Asteroid and Dinosaurs”‚ his original goal was to research more in depth about plate tectonics. Sadly‚ his research was sidelined because of his intriguing observations of the KT boundary. When Geologist make original discoveries‚ they go about researching by highlighting the aspects of the nature of science. For example‚ they test hypotheses about events that happened long ago‚ they rely on communication‚ a lot of evidence‚ and collaboration. Eventually they end up

The Virgin Islands are peaks of a drowned mountain range created by volcanic activity in the Cretaceous. he northern part of the Lesser Antilles comprises two more or less parallel arcs of islands.

Uniformitarianism accounts for these catastrophic events because events that are happening now happened in the past can happen again in present or future time. 4. Geologic processes affect our daily lives through dependence of Earth’s resources. We adapt through changes on Earth from volcanoes‚ floods‚ and earthquakes. We have to adapt to live on the planet.
