Google Earth is a free program from Google that allows you to explore satellite images showing the cities and landscapes of Australia and the rest of the world in fantastic detail.It works on your desktop computer, tablet, or mobile phone.It is publicly important for the prediction and understanding of natural hazards, the remediation of environmental problems, and for providing insights into past climate change.Geology plays a role in geotechnical engineering and is a major academic discipline.This has been achieved by combining exploration methods such as deep seismic surveys with geochronology methods, including use of equipment such as the Sensitive High-Resolution Ion Microprobe, or SHRIMP.This equipment uses uranium and lead isotopes from tiny portions of zircon crystals which have been extracted from rock samples to calculate the age of the crystal based on the natural decay rate of uranium to lead.The images in many areas are detailed enough that you can see houses, vehicles and even people on a city street. Australia is one of 7 continents illustrated on our Blue Ocean Laminated Map of the World.This map shows a combination of political and physical features.

When Geologists and other scientists refer to the age of the Earth, they are using one of two methods to determine this.

Where do scientists begin the story of Earths history?

One place to start is by looking at the age of the materials that make up the Earth itself.

First, we must understand they are dating the rocks and other materials found on the Earth to determine this.

There are two basic types of dating methods geologists rely on, Relative Time Dating and Absolute Time Dating.
