What is it called when a caves have these stones hanging down from the ceiling?
Stalactites are the formations hanging down from the ceiling of a cave due to mineral deposits dripping from the top.
What period was the bow and arrow invented?
The bow and arrow were invented during the Upper Paleolithic period, around 10,000-12,000 years ago. This innovation revolutionized hunting and warfare by allowing for long-range accuracy and increased efficiency in taking down prey.
What hangs down from the cave?
Stalactites are formations that hang down from the ceiling of caves. These mineral deposits are created as water drips through the cave's ceiling and leaves behind mineral deposits that accumulate over time.
The stone age is also called what?
Well, the Stone age is broken down into 3 periods, because it lasted so long. The first period is the paleolithic period ( Old Stone Age ) which began more than 2 million years ago. The second period was the mesolithic period ( Middle Stone Age ) which started around 10,000 BC. The next and last period is the neolithic period (new stone age) which started around 8,ooo BC. That didn't really answer your question.. But it's still knowledge! >: )
What formativein a cave rise from the floor?
Stalagmites grow from the floor of a cave as mineral-rich water drips down and leaves behind mineral deposits that gradually build up over time. These formations can take thousands of years to form and can vary in size and shape.
Why is the Carboniferous period called the Carboniferous period?
Carboniferous means carbon bearing. Large coal deposits were laid down then, hence the name.
How long has coal been in the earth?
Coal has been forming in the Earth for millions of years, with some coal deposits dating back to over 300 million years. The process of coal formation involves the accumulation of plant material in swampy environments, which over time gets buried and compressed to form coal deposits.
How do people find coal?
Coal can be found on the surface in areas in which the overlying strata have eroded. Coal layers can be exposed in road cuts and on the walls of river valleys. Coal can also be discovered by drilling core samples down from the surface.
Why do some places in the US have deposits of coal but others have depositsofpetroleum and natural gases?
It all comes down to the geology of the area as to what is under the mountains.
Why is lead found in all deposits of uranium ores?
Lead is often found in uranium deposits because they have similar chemical properties and tend to form together during the same geological processes. As uranium ores break down over time, lead is a common byproduct of the radioactive decay of uranium. This is why lead is commonly found in association with uranium deposits.
How do they know how much coal is in a coal mine?
They core drill from the surface down and remove samples. These core samples give them the coal seam thickness and coal quality. Multiply the seam thickness by total area and you have the coal reserves, typically measured in acre-feet.
Where do you get coal?
Scientists believe that during the Carboniferous period (280 to 345 million years ago) large amounts of plant life and other organic matter grew in the swampy areas and lagoons that covered much of the earth. As the plants and other life forms died, they drifted down to the bottom of the swamps, slowly decomposed, and formed Peat - a soggy, sponge like material. The peat became buried and compressed under the earth's surfaces over a long period of time. Over millions of years and through the forces of heat and pressure, the compressed peat became coal. The greater the heat and pressure, the harder the coal was that formed. (Source: http://www.teachcoal.org/aboutcoal/articles/faqs.html) One of the largest coal reserves in the United States is in Northern Pennsylvania. You can also find many active coal mines is West Virginia as well. The United States has the largest world reserve of Coal, While China is the largest extractor of Coal.
What caused mass extinction during carboniferous period?
During the Carboniferous period, the mass extinction was likely caused by a combination of factors, including intense glaciation, a drop in sea levels, and significant changes in atmospheric oxygen levels. These factors contributed to significant environmental changes that impacted marine and terrestrial life, leading to widespread extinctions.
Where is hydrogen made?
Hydrogen was made during the period following the Big Bang, even before stars began to form. It was made from the particles that began to condense out as the early universe began to cool down. It is most cheaply obtained from natural gas deposits, though it can also be extracted from water.
Do you throw up during your period?
only if you have a disease or something pretty serious going on with your down there but it is pretty rare that you will throw up on your period.
