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.
29.36 degrees. tan-1(45/80) = 29.36

Glaciers weather surface rocks mainly through the process of abrasion. Intermediate earthquakes occur 70 to 300 kilometers below the Earth's surface.
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.
... without ever doubling back, then you have traveled about 1,111 km (690.3 miles).The number is the same for westward travel.

The Chinook Native Americans traveled through the water on canoes and traveled on ground by foot.
