Origin and Development of Beaches
How are beaches originated? How long do they take to form?

Climatic effects of the impact and volcanism scenarios for the extinction of dinosaurs are investigated in a modelling paper.
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.
EDITORIAL. Those who study historical topics such as origins often face questions for which no easy answers are evident. Nevertheless, there are some things that can be known, and these should not be overlooked. Published in Origins, n. 65.
ARTICLE. In Utah and northern Arizona is a unique geological landscape feature, called the Grand Staircase. Imagine a staircase with each step a thousand feet or more high, and many miles wide. We will discuss hypotheses in regard to how this feature was formed. Published in Origins, n. 65.
In preparation for Creation Sabbath on October 28, 2017, the Geoscience Research Institute (GRI) is creating a series of scientifically accurate and faith building displays. The exhibit will be opened during this year’s Autumn Council of the General Conference Executive Committee, held from October 5-11 at the world headquarters of the Seventh-day Adventist Church in Silver Spring, Maryland. “The displays…
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.
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.
Science is not a straight pathway to total reality and truth, but involves numerous tentative conclusions, reversals of opinion, and inherent uncertainty. Its utility is not that it is always true, but that it is useful and leads to further discovery.
The degree of importance of catastrophes for the geologic history of the earth has been the basis of a long scientific controversy that involves deep time questions.
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…
Glaciations are defined as periods of temperature reduction in the Earth's climate which result in the onset or expansion of continental and polar ice sheets and alpine glaciers. Does the geologic record preserve evidence for the occurrence and extent of former ice ages? What kind of information is used to make these inferences? The answer to these questions has the potential for influencing our models…
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.
A realistic science, not an actualistic one, is led through coherence and consistency of observation with hypothesis, even if it were an"outrageous hypothesis" such as a global planetary flood of the likes reported in ancient history.
To consider a much more rapid, catastrophic geological past challenges the naturalistic origin of life and of major categories of life forms. Do we want to know if that naturalistic interpretation is really correct or not? As scientists, are we open to consider what really happened in the past, or are we satisfied to limit our explanations to fit a pre-determined set of assumptions?
This article details examples of megabreccias of truly immense proportions, ranging from car-sized rocks to rocks a hundred kilometers in length. Such phenomena, spectacular as they seem, are not rare.
