Who on earth named a type of rock apatite?
440823
Apatite is from the Greek apatao meaning "I delude" or "I am misleading"\nThe gene for sonic hedgehog came from the scientist promising his daughter that she could name the gene, and Sonic the Hedgehog was her favorite cartoon character, or so I've heard..

Those are the alkaline earth metals, technically referred to as Group 2.  They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba) and radium (Ra).  Radium has two valence electrons and is in Group 2, but is sometimes left off lists of the alkaline earth metals because it is radioactive.

A lot of them, yes! The creation of the Earth took a very long time, and during that time, many of the rocks you can see today were formed. There are three kinds of rock - \n\nIgneous - from the molten lava once it is cooled\nSedimentary - from several layers of materials compacted together\nMetamorphic - one of the above rocks that has 'morphed' into a different kind of rock

Canada. \n\nThe problem with calling the zircon crystal from Australia the oldest "rock" is that it is a crystal that came out of much younger rock. The rock in Canada is also dated with zircons, but it is intact, and not eroded away. It is slightly over 4 billion years in age. The rocks the 4.4 billion year old zircon came from are only 3 billion years old sediments, formed by eroding the rock the zircon came from. \n\nSo despite the incredible discovery of the Australian zircons, the Acasta River area,in Canada's  Northwest Territories remains the earth's oldest intact rock that we know of.  Unless of course you are willing to call a mineral a rock, in which case Australia wins. \n\nTo demonstrate my point, I quote Wikipedia:\n"Zircon is a mineral belonging to the group of nesosilicates. Its chemical formula is ZrSiO4."

One. It was called pangaea heres some more info:\n\nPangaea or Pangea (derived from Παγγαία, Greek for "all earth") is the name given to the supercontinent that existed during the Paleozoic and Mesozoic eras, before the process of plate tectonics separated each of the component continents into their current configuration. The name was coined by Alfred Wegener, chief proponent of Continental Drift in 1915.\n\nThe continents apparently first coalesced to form Pangaea about 300 Mya (million years ago), giving rise to several prominent mountain ranges by the process known as orogeny. Several of these ranges still exist, although they have become much lower by means of erosion. The Appalachians of eastern North America, the Atlas Mountains of North Africa, and the Urals of Eurasia are prime examples. The mantle under Pangaea's former location seemingly remained very hot even after coalescence, convection currents within the underlying magma pushing the centre of the supercontinent upward. As a result, the area that is now the continent of Africa was situated tens of meters higher than the surrounding continents.\n\nIn configuration, Pangaea was a C-shaped landmass that spread across the equator. The body of water that was enclosed within the resulting crescent has been named the Tethys Sea. Owing to Pangaea's massive size, the inland regions appear to have been very dry due to the lack of precipitation. The large supercontinent would potentially have allowed terrestrial animals to migrate freely all the way from the South Pole to the North Pole.\n\nThe vast ocean that once surrounded the supercontinent of Pangaea has been named Panthalassa. Pangaea, it seems, broke up about 180 Ma in the Jurassic Period, firstly into two supercontinents (Gondwana to the south and Laurasia to the north), thereafter into the continents as we understand them today.\n\nPangaea was not the first supercontinent. From the evidence available, scientists reconstruct that a predecessor, termed Pannotia, formed about 600 Ma, before dividing again some 50 million years later. Another, Rodinia, apparently formed approximately 1,100 Ma and divided 750 Ma.

I believe it's called "Hetfieldenium" named for the man who discovered Metallica, Dr.  James Hetfield.

No specific person named it.\n\nThe English word "earth" has cognates in many modern and ancient languages. Examples in modern tongues include aarde in Dutch and Erde in German. The root also has cognates in extinct languages such as ertha in Old Saxon and ert (meaning "ground") in Middle Irish, derived from the Old English eorðe. All these words are derived from the Proto-Indo-European base *er-. Given metathesis, we can find cognates of "earth" between terra and the modern Romance languages, for instance tierra in Spanish or terra in Portuguese.\n\nSeveral Semitic languages have words for "earth" similar to those in Indo-European languages, although evidence of a link is not overwhelming. Arabic has aard; Akkadian, irtsitu; Aramaic, araa; Phoenician, erets (which appears in the Mesha Stele); and Hebrew, ארץ (arets, or erets when followed by a noun modifier).

3 basic types of rocks\n\nIgneous Rocks-Igneous rocks are crystalline solids which form directly from the cooling of magma. This is an exothermic process (it loses heat) and involves a phase change from the liquid to the solid state. The earth is made of igneous rock - at least at the surface where our planet is exposed to the coldness of space. Igneous rocks are given names based upon two things: composition (what they are made of) and texture (how big the crystals are).\n\nSedimentary Rocks-In most places on the surface, the igneous rocks which make up the majority of the crust are covered by a thin veneer of loose sediment, and the rock which is made as layers of this debris get compacted and cemented together. Sedimentary rocks are called secondary, because they are often the result of the accumulation of small pieces broken off of pre-existing rocks. There are three main types of sedimentary rocks:\n\nMetamorphic Rocks-The metamorphics get their name from "meta" (change) and "morph" (form). Any rock can become a metamorphic rock. All that is required is for the rock to be moved into an environment in which the minerals which make up the rock become unstable and out of equilibrium with the new environmental conditions. In most cases, this involves burial which leads to a rise in temperature and pressure. The metamorphic changes in the minerals always move in a direction designed to restore equilibrium. Common metamorphic rocks include slate, schist, gneiss, and marble.
