Either parsecs or light years (a parsec is about 3.2 light years; it's the distance at which an object shows a parallax of one arc-second when measured on opposite sides of the Earth's orbit).
Approximately 6370km

The SCALE of the map indicates the relationship between lengths measured on a map and the actual distances. It can indicate the ratio of distances (e.g. 1:10000) or the equivalent actual distance for an inch or centimeter as measured on the map, often providing a measurement bar for various distances.
That's the Earth's radius. It's about 6378 kilometers at the equator. That's 3963 miles.
Due to the vast distance between the earth and polaris, the earths axis of rotation essentially lines up with polaris at all times, so when the stars are visible, and viewed from the north pole, the earths rotation causes the stars to appear to rotate around polaris.

it would have to be fractional the sun is not far enough
why scientists use models to represent earths process
What are two ways that's scientists can study earths climates history
The mathematical equation which describes how to measure the distance from Earth to the moon using Earth's diameter as a unit of measure is d = Dcot(p/2)/2 Where d is the distance from Earth to the moon, D is the diameter of the Earth and p is the angle of parallax subtended at moon by the diameter of the Earth.
how does earths distance from the sun change throughout the year
seismometers
scientist use models to show or explain easier
Parallax
AU is a measure of distance meaning astronomical unite. AU is the average distance from the sun to the earth (average because the earths orbit of the sun is not a perfect circle). 1 AU is equal to 149, 598, 000 kilometers. So 1.49 AU is 1.49 x 149,598,000= 222,901,020 kilometers.
it helps the scientists to predict future changes.
