Answer:
When it comes to determining the age of fossils there is absolute and relative dating. Relative dating is used to determine which fossil is older, while absolute dating is used when determining the age of a particular fossil. Rocks that contain radioactive elements in it, allow scientists to determine the age of fossils using the amount of radioactivity. Carbon-nitrogen absolute dating is a method for determining the age of fossils using radioactive isotopes of these elements.

Answer:
When the British column reached Lexington, it ran into an entire brigade of fresh Redcoats that had answered a call for reinforcements. But that did not stop the colonists from resuming their attack all the way through Menotomy (now Arlington) and Cambridge. The colonists protested, “no taxation without representation,” arguing that the British Parliament did not have the right to tax them because they lacked representation in the legislative body. ... Colonists organized boycotts of British goods to pressure Parliament to repeal the Townshend Acts.

Because that all thought it was there land and then treated them horribly
This depends on whether you treat the core as a single layer or split it into the outer and inner core.
The Earth's core has a radius of approximately 3,470 km whereas the Earth's crust is on average only 60 km thick.
This as a fraction is 60/3,470 which can be simplified to 1/58.
That means that the core is approximately 58 times thicker than the crust.
The mantle (which is thickest if you split the core into it's inner and outer components) is 2830 km thick.
This as a fraction is 60/2,830 which simplifies to approximately 1/47.
