Empress Royal Paulownia Tree Step 1: Dig the hole Pick the perfect spot with full or partial sunlight and with moist or well drained soil.

You Can Look It Up - Geologic Words When you get into geology, as opposed to rockhounding, the first thing you need is a dictionary. There are so many different things to keep track of—landforms, minerals, fossils and the parts of fossils—and so many of the words aren't English. Great language though it is, English just isn't up to the task.

Geology Geology gives insight into the history of the Earth by providing the primary evidence for plate tectonics, the evolutionary history of life, and past climates. In modern times, geology is commercially important for mineral and hydrocarbon exploration / exploitation as well as for evaluating water resources. 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 also plays a role in geotechnical engineering and is a major academic discipline. Geologic time[edit] Geological time put in a diagram called a geological clock, showing the relative lengths of the eons of the Earth's history.
