An analysis of the knowledge of the earths interior

The Aurora Australis Over Antarctica Emanating from the South Polar Orifice For centuries, people have referred to our earth, the planet upon which we live, as "mother earth. We don't even think about the air we breath, but we couldn't live without it. The soil and waters of earth grow the food we eat.

Share Shares 4K Alternate history usually examines the consequences and implications of different decisions made by humans at certain times in history. But unless we live in a completely deterministic universe, we can go back even further into deep time to explore the possibilities of very different Earths.

But what if tectonic drift had never happened and Pangaea still dominated one hemisphere with a great Tethys world ocean on the other?

Most likely, we would have a less diverse world biologically because the development of different species occurs mainly through geographic isolation, which causes selective pressures and the development of new genetic traits. It would also experience massive typhoons due to the enormous circulation system in the Tethys that would be unimpeded except by island chains or shallow continental shelves.

During the second historical Pangaean period, mammals dominated in tropical and water-rich monsoon areas while reptiles dominated the great arid areas, largely because mammals use more water when they excrete.

Studies of a transection of Pangaean fossil records show tropical regions dominated by traversodont cynodontsan extinct order of pre-mammals, while the temperate regions were largely occupied by procolophonoids, which resembled stocky lizards and are distantly related to modern turtles.

Different regions of a modern Pangaea might have been dominated by completely different orders of life, a variety of tropical mammal and mammal-like creatures populating the hot and wet regions, and reptiles and pseudoreptiles ruling the roost in the dry interior and temperate regions.

Intelligent life would have been unlikely to develop due to the relative stasis of the environment, but if it had, its effect on the opposite climatic region would have been dire.

During the year, seasons result from our tilted Earth revolving around the Sun and exposing the different hemispheres to various levels of sunlight.

The weather would be much more uniform, although there would be some changes due to variation in the distance from the Earth to the Sun over the year. The northern latitudes would experience a constant winter environment, while the equatorial regions would be humid tropics with heavy rainfall.

Walking north or south from the equator, you would encounter regions with perpetual summer, then temperate spring or autumn, and finally a wintry wonderland becoming more uninhabitable as you approached the poles.

Bucky, an analysis of the knowledge of the earths interior who has no costs, left him aside, and his electrified Rhineland imitated with regret. The thin layer of air that surrounds our planet that supports life The history of the Earth can be organized chronologically according to the geologic time scale, which is split into intervals based on stratigraphic analysis · by Judith. Choose the best possible answer to the following questions about Key Concept 1 "The nature of seismic waves and the nature of Earth's interior." 1. Why has much of our knowledge of Earth’s interior come from analyzing seismic waves?

According to the Rare Earth Hypothesis, this was a good thing for the development of life. A planet with no tilt might not support an atmospherewith gases evaporating into space from the full blast of sunlight at the equator and freezing and falling to Earth at the poles.

If life survived, the situation could still be disastrous for any intelligent species like us.

With seasons nonexistent and constant rainfall in the tropics, growing crops the traditional way would be impossible. Disease would also be more prevalent around the equator.

If an intelligent species like us did develop, they would have little impetus to start an industrial revolution, which was largely driven by technologies first made for heating homes in cold winter months.

If the Earth was tilted a full 90 degrees, seasonal changes would be the most extreme. As the Earth revolved around the Sun, the poles would alternately point directly at the Sun and be perpendicular to the Sun.

One hemisphere would be bathed in sunlight and hot temperatures, and the other in frigid darkness. Three months later, both poles would have a low Sun angle and our equatorial regions would have 12 hours of Sun and 12 hours of night per day, with the Sun rising in the north and setting in the south.

Life developing on such a world may be unlikely due to yearly cycles of radiation sterilization in summer and deep freezing in winter, though some organisms on Earth known as extremophiles might be capable of surviving such conditions. If such extremophiles developed into complex life, they would probably have strong hibernation or migration adaptations.

Artist and avid dreamer Chris Wayan has explored a number of scenarios by altering the points around which the Earth rotates.

He maintained the By removing the ice domes of Antarctica and Greenland, he created a much warmer and wetter world with a potentially higher biomass and diversity.

XKCD also explored the idea, rotating the Earth to put the poles on the equator, a scenario very similar to Shiveria. The site explores the implications for our world cities, turning Manila into the equivalent of Reykjavik, Moscow into an arid desert, and London into a sweltering metropolis.

From the late Jurassic until about 3. Independent evolution continued on both continents for almost million years with some limited biotic exchange via nascent Caribbean islands from 80 million years ago and the Central American peninsula from 20 million years ago. North America, Eurasia, and Africa were dominated by placental mammals without any surviving marsupial species.

All living marsupials actually originated from South America, with kangaroos and opossums sharing genetic ancestors. When the two American continents connected, North American mammals spread across South America, outcompeting most marsupial species.Gentleman, Too the brotherhood, Ahvh-ah, Too the keeper of the key of the great pyramid of giza and his Most Worshipful His Excellency, Sir former Senator Presidential hopeful The Honorable: Mr.
