Re: At Least 2 Killed, 20 Injured During Huge Black Land/mud Slide
I hope so but he kind of went down the road in the direction the mudslide followed.

Re: At Least 2 Killed, 20 Injured During Huge Black Land/mud Slide
...More than 440 Million years ago? You're about 300 million years too early for any monocotyledons to be on the scene, so no there were no prairie grasses...and literally zero member of Poaceae or Poales even on the horizon. For flowering plants, you're around 250 million years too early, and if we're talking about angiosperms, they didn't even arrive on the scene until the Jurassic period, and prior to this, the gymnosperms still only evolved during the Carboniferous period (~350 million years ago). At 440 million years ago is in the Silurian period, and vascular plants were just getting started (and 440 million would be very early given the fossil record). No seeds, no flowers, no differentiation of tissue in leaves, stems, shoots, or roots, and there sure as shit weren't any flowers, or anything you'd come close to recognizing as a flower. Plants of this time reproduced by spores. They didn't even evolve proper reproductive organs until the Devonian period. You really might want to spend some more time reviewing the primary literature on this topic, as when it comes to plant evolution, your facts are very wrong. - From your friendly neighborhood biologist |

What about the 4 seasons thing. It’s not like every where in the world has 4 actual seasons they go thru...

Wonder if that white van got away. That mud was coming fast

I’m just surprised Minka1, Fatmomma or K53 have said “black land” is racist.

Re: At Least 2 Killed, 20 Injured During Huge Black Land/mud Slide
It's important to note that the Earth has had seasons for a very, very long time. One of the key elements that contribute to them is the axial tilt (~23.5 degrees), and that particular trait is quote old...like 4-4.5 billion years ago. The main cause of this tilt was some utterly insane collisions during the early Hadean eon (the name kinda says it all). Depending on the model used, the early Earth...and I do mean early, as we're looking at a period around 200-300 million years after the formation of Sol (our sun), the Earth was struck by some small planet-sized objects (~10). Obviously, the energy transfer of something like this is immense, and is suspected to be the source of our moon. Regardless, the impacts caused the axial tilt to occur. Combine that with our elliptical orbit (again the early solar system was not a safe place to be, and even been given such happy titles as the Late Heavy Bombardment Period), and some of the biggest factors are already in place. From that point on, it really becomes a question of how you want to define the seasons. If you just want to look at a global scale, and demarcate the seasons by periods of specific temperature, well we still needed an atmosphere...and water, both of which took a bit longer to form, but they were present in some form or another at the end of the Hadean eon. On a local scale, again we need to look at what was present. Life, beginning with Archea, then prokaryotes, mostly formed in large bodies of water, but also some of the earliest organisms on land, appeared in and around the equatorial region of the super-continent, Pangea). Just as is the case today, equatorial regions have fairly constant temperatures, as well as day lengths compared to the polar regions, so they wouldn't experience much in the way of the classic 4 seasons...maybe something like dry/rainy season. So places on Earth would have had different seasons probably starting from a couple of billion years ago, but there wasn't anything present to experience much of it except for rocks and water. Does this help? |

Re: At Least 2 Killed, 20 Injured During Huge Black Land/mud Slide
https://www.weather.gov/cle/seasons Seasons are caused by the fact that the Earth is tilted on its axis by 23.5°. The tilt's orientation with respect to space does not change during the year; thus, the Northern Hemisphere is tilted toward the sun in June and away from the sun in December, as illustrated in the graphic below. Around 78° Lat. and above isnt that were the sun does not set for several days once a year? It just stays above horizon  |
