How are beaches originated? How long do they take to form?

New observational data on the phenomenon of rapid bedrock erosion became recently available after the well documented events that affected the Oroville Dam in February 2017.

A Christian scientist, while accepting the testimony of Scripture about God’s past intervention in Earth’s history, can still keep an open mind toward aspects of the geologic record that are unusual and different.

Can we learn more about the qualities of the Creator through the study of geology?

The hypothesis of a large meteorite impacting the surface of the Earth at the end of the Cretaceous was introduced almost four decades ago. In the ensuing years, the geologic community gathered a large body of data in support of this hypothesis, elevating it to the status of a universally accepted fact of Earth history. However, competing models and lively discussions are still unfolding over the dynamics and environmental consequences of this large impact.

Is Genesis History? asks a question that many Christians struggle with. Is the first book of the Bible comprised of pious myths? Is it an allegory designed to teach important lessons about God, but not actually a record of the history of life on Earth? Or is it a reliable record of events that actually occurred in the past? In other words, is Genesis the oldest book of history available today, one…

Iceland is a volcanic island in the North Atlantic Ocean, slightly below the Arctic Circle. The island is situated on a mid-ocean ridge at the boundary between the North American plate and the Eurasian plate. In Iceland, we find evidence of horizontal movements, in which two plates spread apart as the crust dilates with intrusion of new magma. Iceland, however, is also associated with a mantle plume (a narrow stem of upwelling of magma from deep in the mantle) that has maintained volcanism high and vigorous.

In 1813, French geologist Alexandre Brongniart published a paper on the mineralogical classification of rocks where he introduced the new name “ophiolite” for a suite of dark rocks rich in the mineral serpentine. The name was coined from the Greek words for “snake” and “rock,” which seemed fitting, given the smooth dark green appearance of ophiolites, vaguely reminiscent of snake-skin.

The term Cenozoic (or Cainozoic) means “recent life,” implying that the fossils encountered in these layers are more similar to modern species.

The rocks of the Earth are like pages of a history book containing information about the past. Geologists who enjoy reading this “book” have found that it consists of two “volumes:” the first, named Precambrian, is mostly devoid of macroscopic fossils. The second, named Phanerozoic, contains layers and sediments providing a rich archive of past forms of animal and vegetal life. The Phanerozoic “volume”…

This third part of a series on the Precambrian provides two perspectives suggested by creationists on how to interpret this portion of the rock record.

This second part of a series on the Precambrian describes Precambrian rock exposures, as well as the atmosphere, climate, and Precambrian life. Many illustrative pictures are included, and design examples and creationist ideas are interspersed throughout.

This first section of a 3 parts series on the Precambrian summarizes the standard model for formation of the Universe, Solar System and Earth, Moon, oceans, continents, and plate tectonics. Brief references to the Universe, Sun, and Moon are included because what happens beyond Earth sets the stage for what happens on Earth during the Precambrian and in the Genesis 1 account.

This article provides an introduction to mineralogy and outline the different mineral categories, discusses some interesting features about minerals, describes the formation of minerals in different environments, and mentions some minerals referenced in the Bible.

The world must have seemed like a big place to Helga Estby, a Norwegian woman who walked across America in the year 1896. Helga immigrated to the United States with her parents in 1871 at the age of 11. On May 5, 1896, at the age of nearly 36, Helga and her 18 year old daughter Clara set out to walk across the United States. They started from Mica Creek, in far eastern Washington state, and walked…

Texbooks describe the fossil record as the ‘best evidence’ for evolution. They claim that the fossil record proves evolution because there seems to be a succession from simpler to more complex life forms, and a succession from marine to terrestrial forms. Charles Darwin suggested that all life has a common ancestor. “All the organic beings which have ever lived on this earth may be descended from some…

The first book of the Bible states that following a recent creation by God, there was an astonishing worldwide Flood. In that context, the Flood would have been responsible for most of the great fossil bearing layers of the earth. However, current scientific interpretations propose that these layers slowly accumulated over billions of years thus allocating more time for the slow gradual evolution of…

The rocks found on the surface of the Earth did not form all at the same time. Geologists schematize this different order of formation using a column, of which the lower layers represent older rocks and top layers represent younger rocks. Archean rocks are the ones at the very bottom of this geologic column, and are therefore interpreted as the oldest rocks. They are often heavily deformed and altered…

The Adventist faith will not be itself if it accepts theistic evolution. The active God who created by the word of His mouth, who communicated through the prophets, who lived among us, died in our place, was resurrected and ascended to minister for us, who will return the second time to gather us to Himself, who will resurrect the dead and re-create the new earth, and who will finally destroy sin, cannot be worshiped if He does not exist. This article was originally published on Perspective Digest, v. 18/4.

To model the motion of Earth's plates, Baumgardner uses a Fortran program he developed called TERRA that must be run on a supercomputer. It is one of four models in the world capable of modeling Earth in a global manner.
