1
Q

Define fossils

A

fossils used to identify a geologic system because they lived either (a) at a certain time or (b) in a certain place in the pre-Flood world

2
Q

Define Geologic column

A

a columnar diagram identifying rocky layers (strata) that form a sequence from bottom to top to indicate their relationship to the twelve geological systems

3
Q

Define living fossils

A

creatures found alive today that evolutionists thought became extinct millions of years ago

4
Q

Define trilobite

A

a crab-like creature was the first fossil found buried in abundance around the world

5
Q

Define Cambrian explosion

A

the sudden appearance of a wide variety of complex life forms in the lowest rock layer with abundant fossils. (Cambrian); considered a challenge to evolution, these may be the first organisms in a corrupted creation to be buried in Noah’s flood.

6
Q

Define cavitations

A

bubbles formed by surging waters

7
Q

Define Paraconformities

A

a gap without erosion in the geologic column diagram; breaks the time sequence assumed by evolution, and may suggest fossils from different environments were rapidly buried by a lot of water, not a lot of time

8
Q

Define stromatolites

A

banded rock deposits formed by blue-greens growing in mossy mats on rocks in the tidal zone along the shore; the mats trap and then cement sand grains to form a mineral layer, continually building new layers on top of earlier ones

9
Q

In what types of rock are most fossils found? Where can we see these layers of rock?

A

Sedimentary rocks (limestome, shale, sandstone); cliffs, cuts, creeks, and quarries

10
Q

How many major geologic systems have been named? How many “super systems”?

A

12; 3

11
Q

Who said that fossils are “perhaps the most obvious and serious objection to the theory of evolution”? Why is this significant?

A

Charles Darwin; Charles Darwin realized that evolution needed viable evidence of transitions from one animal into another; without them, evolution could not be validated

12
Q

According to Flood geologists, what does the geological column show?

A

a series of burials

13
Q

Explain why fossils of sea creatures are found throughout the geologic column while animals and land plants tend to be found higher in the column.

A

Since they were buried later in Noah’s flood, paleosystems with land plants and animals occur higher in the geologic column diagram than those with only sea creatures, but fossils of sea life occur in all geologic systems or eco-sedimentary zones since the Flood waters eventually covered all the land.

14
Q

What tilted the basement rocks of the earth’s surface?

A

The waters that burst out of the deep during Noah’s Flood

15
Q

How do the crystalline basement rocks found in Grand Canyon give testimony against millions of years of erosion?

A

If the millions of years scenario were true and erosion occurred gradually, the softer rock would be gone and the hard rock would stick up into the sediment above. However, the tilted layers have been sheared off in a nearly straight line.

16
Q

Describe the “breached dam” concept for the formation of Grand Canyon.

A

The bottom layers were most likely formed in the years before the Flood and sheared off during the beginning stages of the Flood. The upper layers were set into place during the Flood. Tectonic activity pushed these layers up as the water receded from the earth’s surface during the later stages of the Flood. Water became trapped by earthen dams, which finally broke years after the Flood and released water to where we see the Colorado River through the gorge of Grand Canyon.

17
Q

What event supported the Flood geologists’ interpretation fo Grand Canyon’s formation?

A

Mount St. Helens
