There are 17500 years in 1 lightyear, so 17500x3= 52500 years for three lightyears.
Usually 3 but can also form 5 - with Fluorine for example.
Unknown, but one theory is appx 240m years. There is much that is still not understood about the mysterious geode.
Phosphate has a valency of -3 when it is in its ion form (PO4^3-). It can also form compounds with other elements where the valency can vary depending on the specific compound.
One season on Earth typically lasts around three months. This is due to the tilt of Earth's axis as it orbits the sun, causing variations in temperature and weather patterns throughout the year.
Crude oil forms in the Earth's crust over millions of years through the decomposition of organic matter under high pressure and temperature. It typically takes anywhere from 1 to 3 million years for crude oil to form.
In terms of the speed of light, the distance between the Earth and Sun is81/3 light minutes,or about 0.00001585 light-year.
if you are in year 9, then you are in form 3. the way to work this out, is by starting at year 7 and counting up from there for example: year 7= form 1 year 8= form 2 year 9= form 3
