The Grand Staircase: a Case Study in Scientific Thinking from a Biblical Worldview

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.

Sand Dunes of the Sahara: How Should We Relate Scripture to Earth Science Questions?

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.

What Is the Evidence for a Large Asteroid Impact at the Cretaceous-Paleogene (K-Pg) Boundary?

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.

A Review of the Documentary Film “Is Genesis History?”

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…

Alpine Ophiolites: Remnants of a Lost Ocean

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 Cenozoic

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

The Paleozoic Rock Record: A Broad Overview of Features and Trends

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”…

The Precambrian: Part 2 of 3

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.

The Precambrian: Part 1 of 3

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.

The Cambrian Explosion

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…

Was There A Great Genesis Flood?

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 and the Geologic Record

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…

Traces of Life from Archean Rocks: Evidence and Challenges

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…
