The age of the Earth is 4.54 ± 0.05 billion years (4.54 × 10 9 years ± 1%). This age may represent the age of the Earth's accretion, of core formation, or of the material from which the Earth formed. This dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples. Essential concepts of chemistry related to earth materials. Basic concepts of chemistry are essential to understanding the physical and chemical properties of earth materials (minerals, rocks, organic matter, etc.). Overview: The theory of evolution describes an earth that is about 4.5 billion years old. But many creation scientists interpret the Genesis account of creation as requiring an earth that is only 6,000 to 10,000 years of age.There are numerous indicators that the earth was in existence billions of years ago. Creation Versus Evolution: We compare the theory of evolution with the Bible’s creation account in easy-to-understand terms, using evidence from the fields of paleontology, geology, biology, and astronomy.We provide links and a bibliography for those who want to study both sides of the issue. acquired trait: A phenotypic characteristic, acquired during growth and development, that is not genetically based and therefore cannot be passed on to the next generation (for example, the large. How radiometric dating works in general : Radioactive elements decay gradually into other elements. The original element is called the parent, and the result of the decay process is called the daughter element. An ice core is a core sample that is typically removed from an ice sheet or a high mountain glacier.Since the ice forms from the incremental buildup of annual layers of snow, lower layers are older than upper, and an ice core contains ice formed over a range of years.

The theory maintains that plant evolution, animal evolution and the major geological changes to the earth unfolded over billions of years. How many years is a "long time"? We often express time in hours or days, and 10 or 20 years certainly feels like a long time. Imagine if you needed to think about one million, 100 million, or even several billion years. The secondary science program is guided by the vision that all students, regardless of gender or cultural background, are given the opportunity to develop scientific literacy.
