Were rocks and minerals catologued around 200 BC by Greeks?
Yes, the Greeks catalogued rocks and minerals around 200 BC, particularly by scholars like Theophrastus who wrote extensively on the subject in his work "On Stones." They classified minerals based on physical properties like color, hardness, and luster, laying the foundation for modern mineralogy.
What originates 60 to 200 below earth's surface?
Mantle minerals such as olivine and pyroxene originate between 60 to 200 kilometers below the Earth's surface. These minerals are brought to the surface by volcanic activity through processes like magma rising from the mantle and erupting as lava.
How uranium is stored in nature as it radioactive element?
Uranium is primarily found in the Earth's crust in the form of uranium oxides, such as uraninite. These minerals can exist as solid deposits in rocks or as part of sedimentary layers. Due to its radioactive nature, uranium undergoes decay processes that produce various daughter isotopes, contributing to its radioactivity.
How does shale turn to slate?
Shale turns into slate through a process called "low-grade metamorphism." Under heat and pressure, the clay minerals in shale recrystallize to form very fine-grained mica minerals, giving slate its characteristic layering and foliation. This metamorphic process occurs at temperatures between 200-450°C and pressures of 200-300 megapascals.
Rocks in ocean crust are as old as?
200 million

Where does the element uranium occur in nature?
Uranium is around us: in rocks and minerals (more than 200 minerals contain uranium), in soils in all waters including the tap water, in the atmosphere, building materials, vegetation etc. Uranium is not a so rare chemical element.
How old are the oldest rocks found on the sea floor?
Around 200 million years of age.
How many mineral groups make up most rocks?
About 200 minerals make up the bulk of most rocks. The feldspar mineral family is the most abundant. Quartz, calcite, and clay minerals are also common. Some minerals are more common in igneous rock (formed under extreme heat and pressure), such as olivine, feldspars, pyroxenes, and micas.
What is the recommended daily intake of minerals?
It should be around 1,400mg a day give or take 200, hope this helps =]
Where do you find minerals?
Any rock contains minerals. So does all food. If you are looking for minerals, rocks and mineral specimens, you can find them everywhere in nature.
How fast could trebuchets fire rocks?
Trebuchets could fire rocks at a speed of around 160-200 mph, depending on the size and design of the trebuchet. The larger the trebuchet, the higher the potential speed of the projectile.
What is the most recent knot?
the siberian king kong knot, it takes even experts around an hour to tie this knot, which uses generally around 200 meters of rope and is used for hanging artificial rocks, big rocks!
What is the approximate age of the Atlantic Ocean seafloor rocks in million of years?
The seafloor rocks of the Atlantic Ocean are generally around 200 million years old, with the youngest rocks found near the mid-Atlantic ridge, formed by seafloor spreading. As you move away from the ridge, the age of the rocks increases, with some older sections dating back to the Jurassic period. The oldest seafloor rocks are typically found near the continental margins, where they can be over 200 million years old.
Rocks in ocean crust are as old as years.?
200 million
What temperature is sedimentary rock formed at?
Sedimentary rocks can be formed at any temperature found on the surface of the Earth. Diagensis of sedimentary rocks occurs at temperatures up to the formation of chlorite (200C) from then on they are metamorphic rocks.
Rocks in ocean crust are as old as how many years?
Rocks in ocean crust are generally as old as 200 million years. The oldest oceanic crust is found near continents, which can be around 250 million years old. However, most of the oceanic crust is continually being formed and destroyed through seafloor spreading and subduction, so rocks are often much younger.
