Use the links below to explore available resources covering major concepts associated with the study of the history of the Earth.Resources in this section pertain to the formation and evolution of the Earth and how it has been discovered through the relative and absolute dating of rocks and fossils.We note here, that volcanism throughout Earth history is responsible for outgasing of the Earth to help produce both the atmosphere and hydrosphere.Volcanism helps renew the soil, and soils around active volcanoes are some the richest on Earth.The greatest killers have been pyroclastic flows, tsunami, lahars, and famine.Beneficial Aspects of Volcanism Since this course concentrates on the damaging effects of volcanism, we won't spend too much time on the topic of the beneficial aspects of volcanism.The video is dedicated to the 23,000 people who died as a result of mudflows (lahars) from the 1985 eruption of Nevado del Ruiz volcano in Colombia, and is intended to help prevent similar disasters in the future.

Hydrothermal processes associated with volcanism produce rich ore deposits, and the heat rising around magma bodies can sometimes be tapped to produce geothermal energy.

With the advent of modern biotechnology, researchers have been able to determine the actual sequence of the roughly three billion bases of DNA (A, T, C, G) that make up the human genome.

Radioactive substances give off protons (positive particles) and neutrons (neutral particles) at a steady rate.

Eventually, these substances change into different elements. For example, an isotope of uranium, U-238, will eventually decay into an isotope of lead.
