Where did soil come from?

[kwerk]

Earth started as a big rock in space, with molten rock inside. Maybe a comet smashed in to it and brought water. So we have a rock and water.

Where the hell did soil come from? It's made of organic material right, but plants need soil to grow in the first place Perhaps it started from sea life (algae and stuff) being washed up on land rock?

Explain.

It comes in bags?

Springtails, or so a recent book I bought on Poison Dart Frogs suggests.

but plants need soil to grow in the first place

Yes, but they don't need the perfect soil that we have today. The original soil came from rock that had been broken down by water. This was not the soil you see today. It was more like sand. This is not good for the plants of today to grow in but is was sufficient for basic plants to grow. These plants would then over time die and their remains became a more hospitable soil that more complex plants were able to grow in.

So, the soil you are refering to indeed comes from the remains of dead plants, and to a lesser extent, insects and animals.

When a mummy rock and a daddy rock love each other very much, they hug and kiss a lot. But if mummy rock doesnt want to get pregnant, daddy rock pulls out and spews his rock juice on mummy rocks face. Anything that falls off becomes soil.

Look up "Rock Cycle"....that should explain everything.

 

[edscdk]

I have always assumed that soil is part ground up rock and part organic stuff,

originally it would have jsut been ground up rock, then groud up rock and part what ever plant / animal / life had evolved at the time...

 

[J-FRO]

Yes, but they don't need the perfect soil that we have today.

Further to your point, that is precisely why plants also grow on cliffsides. There's no soil there, they just dig their roots into tiny cracks and get going.

Genuine LOL, right there

+1 here

Soil is just plant life and organic material.

Think about a forest, with all the leaves, and pine cones, and seeds, and animal droppings etc all falling to the ground and sitting there, eventually turning into dirt.

Now, look at some volcanic places in Hawaii, where trees and plants actually grow out of cracks in the fresh lava rocks, with no soil. This would explain how it can start without an abundance of soil. Its amazing to see a totally barren volcanic landscape, with little trees starting to grow!

Soil isn't just organic material, infact the vast majority ISN'T organic material, and most of the "usable to feed/create life" organic material is simply phosphorus, potassium, nitrogen.

A tomato doesn't grow and then fruit because its eating organic material, its eating on old organic material broken down into its base parts, which were there the whole time.

Where did soil come from, ball of molten elements orbiting the sun that eventually cooled down which let the surface harden.

Where did that from, unthinkable amounts of times and life cycles of stars forming and blowing up while forming new elements, spreading across space, and forming solar systems.

Double LOL

 

[greywolf]

So...

Archaeologists have to dig down to find stuff. Which means the World must be getting bigger as there is now more soil.
