Where Is Our Desert Biome?
Where is our desert biome? The common thought in the science fiction community is that the space around our sun is the desert.
But that would not make any sense if aliens had inhabited other planets. Why should they build in the midst of a desert? In fact, no one knows where their deserts are. If we were to go into a space with a less than hospitable atmosphere, the burning of organic materials would drive up the surface temperature to well above 200 degrees, similar to what could happen in the surface of Venus or Mars.
Fortunately, most of the atmosphere on earth is made up of nitrogen and oxygen. Nitrogen is helpful because it can maintain the right kind of density for water to exist. Oxygen is needed for the plant life to survive. It’s hard to see how the earth would have an atmosphere without either of these substances.
Nitrogen is not present at all, but that does not mean there is no nitrogen in the atmosphere. All the water has to be broken down, so nitrogen has to get through. Much of it gets stuck in the rocks, and some goes into the oceans.
One place to look for nitrogen is in the fossils that form when water flows over rock. The best place to look for the nitrogen is in the layers below. The longer they are buried, the deeper they will go.
Of course, you cannot expect to find it in all the layers; the left-over material that the water gets left behind makes up only a small percentage of the total. That’s why it is important to get it out of all the layers so you can compare the amount of it to where it should be.
If the nitrogen was there, then there should be nitrogen in the top few inches of the earth’s surface. But, we know that some of the oxygen would have long since been oxidized, because we have found excess oxygen in the oceans.
Perhaps the initial atmosphere was nitrogen-rich, and it gradually became oxidized. It’s quite possible that the more modern atmospheres have gotten even more earth-like private desert safari dubai.
In Australia, for example, they have much higher amounts of nitrogen in the surface sand than they do in the ocean. This probably comes from the air getting replaced by the scrubland as it rains. That means a lot of nitrogen ended up in the soil.
When the weather changes from wet to dry season, the scrub becomes even more alkaline. Water moves in, and it mixes with the existing atmosphere. So, it’s not surprising that there would be an abundance of nitrates, ammonium, and other minerals in the surface soil.
In that same dry season, plants get a chance to grow in the areas where there is very little water, so they can take advantage of the good water supply during the high concentration of nutrients. They might even be able to compete better than they do now, as they have the chance to migrate up the hillsides.
When water floods through cracks in the land, it may come in with a lot of oxygen. It is a good environment for the plants that are not adapted to the strong air pressure. That’s what scientists are trying to learn about how early life evolved on earth.
