Origin and Development of Beaches
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.
Fossils are remains of organisms or traces of their activity preserved in the rock record. The scientific significance of fossils is truly remarkable, because they represent the only available archive of past forms of life. Through fossils, not only can we reconstruct the morphology of extinct creatures but also infer aspects of their ecology and environment. Fossils are also very relevant in discussions…
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…
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.
Plate tectonic theory seems to be well-founded, but the science does not fit easily with a recent one-year flood. However, as is the case in many other areas of human investigation, when we study origins issues, we must trust the details to an all-wise God, since His “foolishness” is greater than our wisdom.
