The Devonian spanned roughly from 419 to 359 Ma. The period was a time of great tectonic activity, as Laurasia and Gondwana drew closer together. The continent Euramerica (or Laurussia) was created in the early Devonian by the collision of Laurentia and Baltica, which rotated into the natural dry zone along the Tropic of Capricorn. In these near-deserts, the Old Red Sandstone sedimentary beds formed, made red by the oxidized iron (hematite) characteristic of drought conditions. Near the equator Pangaea began to consolidate from the plates containing North America and Europe, further raising the northern Appalachian Mountains and forming the Caledonian Mountains in Great Britain and Scandinavia. The southern continents remained tied together in the supercontinent of Gondwana. The remainder of modern Eurasia lay in the Northern Hemisphere. Sea levels were high worldwide, and much of the land lay submerged under shallow seas. The deep, enormous Panthalassa (the "universal ocean") covered the rest of the planet. Other minor oceans were Paleo-Tethys, Proto-Tethys, Rheic Ocean and Ural Ocean (which was closed during the collision with Siberia and Baltica).
What continent was formed when Laurasia and Gondwanna colided?
A: unanswerable

Assuming the player's optical pickup is in proper working order, crosstalk distortion normally does not occur during playback of CAV format LaserDiscs, as the rotational speed never varies. However, if the player calibration is out of order or if the CAV disc is faulty or damaged, other problems affecting tracking accuracy can occur. One such problem is "laser lock", where the player reads the same two fields for a given frame over and over again, causing the picture to look frozen as if the movie were paused.
In which format does crosstalk generally not occur?
A: CAV

Victoria turned 18 on 24 May 1837, and a regency was avoided. On 20 June 1837, William IV died at the age of 71, and Victoria became Queen of the United Kingdom. In her diary she wrote, "I was awoke at 6 o'clock by Mamma, who told me the Archbishop of Canterbury and Lord Conyngham were here and wished to see me. I got out of bed and went into my sitting-room (only in my dressing gown) and alone, and saw them. Lord Conyngham then acquainted me that my poor Uncle, the King, was no more, and had expired at 12 minutes past 2 this morning, and consequently that I am Queen." Official documents prepared on the first day of her reign described her as Alexandrina Victoria, but the first name was withdrawn at her own wish and not used again.
Who came to tell Victoria that she was to be Queen of the United Kingdom?
A: Archbishop of Canterbury and Lord Conyngham

Child labour has been a consistent struggle for children in Brazil ever since the country was colonized on April 22, 1550 by Pedro Álvares Cabral. Work that many children took part in was not always visible, legal, or paid. Free or slave labour was a common occurrence for many youths and was a part of their everyday lives as they grew into adulthood. Yet due to there being no clear definition of how to classify what a child or youth is, there has been little historical documentation of child labour during the colonial period. Due to this lack of documentation, it is hard to determine just how many children were used for what kinds of work before the nineteenth century. The first documentation of child labour in Brazil occurred during the time of indigenous societies and slave labour where it was found that children were forcibly working on tasks that exceeded their emotional and physical limits. Armando Dias, for example, died in November 1913 whilst still very young, a victim of an electric shock when entering the textile industry where he worked. Boys and girls were victims of industrial accidents on a daily basis.
When was Brazil colonized?
A:
April 22, 1550
