Excellent 10 part documentary on Amazon Prime (sorry)” Voyage of the Continents”

“Since it was formed 4.55 billion years ago, Earth has been subjected to incredibly powerful forces. Around its molten core, the earth’s crust is in perpetual evolution, tirelessly redesigning the map of the continents and oceans. The history of the continents is evidenced through tectonic forces, which continuously create and destroy the boundaries of land and sea”

If I remember correctly, North America is moving and on track to bump into Europe in the future. It really makes the climatologists look insignificant in their thinking. How arrogant to think they can control future climate with such massive forces at work.

I’ve watched a volcano in Iceland fill a valley with lava in 4 months. I watched as a road was washed out and a cement bridge with a 20 foot cavern left behind in 4 hours. You can’t make me believe it took millions of years to carve out a canyon.

That rock was unconsolidated. Basically, it was sediment and not rock. Sediments need to be buried within the earth to become rock. At a minimum, about 4,000’ before the process begins. One exception are reefs which are lithified as they are created. Think about peat that forms in a swamp. It has to be buried quite a ways before it becomes coal.

There aren’t any fossils in most metamorphic rocks. Maybe in a marble, which is metamorphosed limestone.

Certainly any position regarding origins requires belie, faith and confidence in an operational framework, so I accept that my world view regarding origins is non-primary scientific based. So is theirs.

I understand that evidence based study, historical if you will, requires an interpretation.

In primary science, a test is performed repeatedly and results documented, then the theorem is either confirmed, denied or the test understood to be lacking, so we try again.

Time replaces an actor. The idea being that given enough time, anything can happen, which is payentedly false. Always an input is required.

Defies logic otherwise.

It takes gobs more faith to accept that “nothing did something” than it does to accept that a living Creator built a place for His creation and loves His creatures.

Most of the rocks exposed on the Ozark Plateau are from the Mississippian Period. They represent only a fraction of the rock exposed in the Grand Canyon. Specifically, the Redwall and Surprise Canyon Formations.

There is a large plume of magma situated beneath the Colorado Plateau. It is more buoyant (lighter, since it is melted) than the surrounding rocks of the mantle. This causes the area around the Colorado Plateau to be uplifted a few inches every thousand years or so. The river can easily erode through this amount of uplift and create the canyon.

The grand canyon was formed by a stream of water flowing uphill for billions of years.
Don’t you have a science book?

Well, I guess the “rock” formed since the recent eruption of Mt St Helens isn’t...

Crystallization/bonding is all that is required per evidence. “Time” is not of the essence. Massive amounts of water dissolving calcium and or other minerals provides ample cementing.

In your example of a swamp and coal, the critical factor is depth and hence more importantly time. However, even in oxygen depleted conditions, organics don’t last eons. Unless they were buried rapidly...

Volcanic ash is a little different. Some cools in the atmosphere and comes down as ash. Some is still hot when it reaches the earth and solidifies.

Yeah, but I turned it upside down.

You see, as a kid I played on the dirt, made rivers and streams and watch stuff move, helped build earth works with my Dad and Grandpa, saw things up close.

The more water, the more and faster movement. Radical inputs brought about radical changes, but minor inputs didn’t do much at all. Hence the need for “time immemorial”, I didn’t fall for it in HS.

Indeed, I spent several years in college as a youth getting the indoc, but I always wound up asking “why” and that bothered most of the profs. I finally figured out they didn’t know why, but were glad to get the paycheck and repeat the mantra....

One Biology Prof did care He was kindly enough to hand me a well marked up copy of the book of Genesis.

God, creation, the flood, young earth, the Bible! they should read it, that would help! putting your faith in more fake science wont help!

My apologies. I do love me some Buffalo River.

Apparently six million votes for Biden were found near the great uncomformity. About eight million of them were said to be “legitimate” by a political scientist. Another forty seven million were “probably legitimate.”

Cool name for a geology student."

How about some gneiss schist?
