What was the climate like in the carboniferous period in the geological time scale?
Hot, steamy, with abundant rainfall, tropical in nature, perfect for plant and forest growth.
There is no definite length of a geological time scale, unless you wish to use some 13 billion years which the universe has existed for. The geological time scale tends to use the units of time: 109 (billion) years, and 106 (million) years. E.g. the Earth is 4.6 billion years old; the Carboniferous period was around 350 million years ago. The scale is greatly varied. If you were to plot all major events, you might…
In Geological Time Scale which is arrangement of earth's history on the time scale as Eons, Eras, Periods and Epochs to explain the past biotic and abiotic history of earth and life. Eons: is the LARGEST unit of Geological Time Scale differentiated on the basis of life present or absent. Eras: is the SECOND LARGEST unit of Geological Time Scale that is differentiated of the basis of geological changes that earth has undergone.
The geological time scale is divided into: Eons (Such as the Proterozoic and the Phanerozoic) THEN Eras (Such as the Mesozoic and the Cenozoic) THEN Periods (Such as the Cretaceous and the Quaternary) THEN Series, alternatively Epoch (Such as the Pleistocene and the Holocene) THEN Stage (Such as the Campanian and the Tarantian)
What times would be the longest a paleozonic b carboniferious period c Jurassic period d mesozoic era?
According to the newly released Geologic Time Scale (June 2012) these are the durations of the given options: a) Paleozoic: 258.8 million years b) Carboniferous: 60.0 million years c) Jurassic: 56.3 million years d) Mesozoic: 186.2 million years Its not surprising that the Carboniferous and Jurassic are the shorted as both are Periods one of the given Eras. So the Paleozoic is the longest of the four options.
there is no word called carboniferous carbon is an element that has a grayish blackish color. its most common molecule is carbon dioxide. if you add that to the time scale, the carbon dioxide will add up in the atmosphere that we live in. ifyou add 2010 then you havethe amount of carbon dioxide in the atmosphere in the year 2010... which is alot. and people are tryingto reduce carbon emissions.
The longest periods of the geological time scale are eons. Each eon is divided into eras and each era is made up of periods, which are further divided into epochs. Each division ended when a significant geological event occurred, such as a major ice age ending or a meteor impact resulting in a mass extinction of animal life, etc.
The Geological Society has this page, but there are few events mentioned: http://www.geosociety.org/science/timescale/ There is an iPhone app for the Geologic Time Scale. And, the makers website has a demo with some of the facts illustrated: http://www.tasagraphicarts.com/geotimescale.html Dan firstname.lastname@example.org
In the past climate change has been a very short-term thing compared with continental drift. The have been several ice-ages in the last 100,000 years, and the continents have drifted imperceptibly in that period. On a scale of 100s of millions of years then continents drifting towards or away from the poles will of course see very slowly changing climate over that very long period.
What was used by geologists to define the beginnings and ends of the division of the geologic time scale?
Rocks contain what we call "Clocks" these can be minerals which are resistant to weathering such as Zircon. They are used to estimate absolute ages of Geological structures.Using these clocks combined with the Geological events i.e drastic Changes to the earths environment leading especially to extinction of specific animal species eg.Dinasours and the type of Organisms that existed at that time,the geological time scale is born
