It depends on your latitude. At the equator (0 degrees) a degree of longitude covers just over 111 km, so 8 degrees would be about 890 km.
At 45 degrees of latitude, a degree of longitude covers just under 79 km, so 8 degress would be about 555 km.
Check out the calculator in the related link. Enter the degrees of latitude and it gives the length of a degree at that point.

The difference between plane and spherical triangles is that plane triangles are constructed on a plane, and spherical triangles are constructed on the surface of a sphere. Let's take one example and run with it. Picture an equilateral triangle drawn on a plane. It has sides of equal length (naturally), and its interior angles are each 60 degrees (of course), and they sum to 180 degrees (like any and every other triangle). Now, let's take a sphere and construct that equilateral triangle on its surface. Picture an "equator" on a sphere, and cut that ball in half through the middle. Set the top half on a flat surface and cut it into four equal pieces. Now if you "peel up" the surface of one of those quarters and inspect that triangle, it will have three sides of equal length, and will have three right angles. Not possible on a plane, but easy as pie on the surface of a sphere. Spherical trig is the "next step up" from plane trig.

The deepest humans have traveled into the Earth is about 7.5 miles (12 kilometers) through deep mines. This achievement was in the Kola Superdeep Borehole in Russia.
Approximately 12,742 kilometers. This distance is from the surface of the Earth to the center and then to the opposite side.
On the surface, about 11,000 F. But to get to the surface, you'd have to travel through the corona, which is believed to get as hot as several million degrees F.
It's -110 degrees Celsius according to a website called "Journey Through the Galaxy".
He traveled from Spain to Florida and through the Caribbean.
A few men have traveled through space faster than sound travels through water but no manned vehicle has traveled through a liquid faster than sound through that liquid.
Radiation from the Earth's core can travel up to several thousand kilometers to the surface. Radiation from the sun that reaches the Earth travels about 150 million kilometers.

A stock is a feature similar to a batholith, but smaller in size with less than 100 square kilometers exposed at the surface. Stocks are also intrusive igneous bodies formed beneath the Earth's surface through the consolidation of magma.
