Since the metric system is the system of measurement used in all sciences, Celsius is usually the form of temperature measurement used.
Kilometers or Miles
Latitude and Longitude
There are three main types of excavation: topsoil excavation, rock excavation, and muck excavation. Topsoil excavation involves removing the top layer of soil; rock excavation involves breaking and removing solid rock; and muck excavation involves digging soft, wet, and unstable soil.
its used to dig holes
The bent tube Earth thermometer is a kind of a measurement that is used for measuring temperature of the earths crust.
A backfill is the material which has been used to refill and excavation.
Astronomical Unit- The distance between objects in the solar system!
The unit of measurement used to measure gravity (G's) is actually based off of Earth's gravitational pull; one G is the level of gravity on Earth.
AU is not used to measure the distances on earth, because a astronomical unit is a unit of measurement equal to the distance between Earth and Sun. So that's why you cannot use Au for measure the distances on Earth.
The answer depends on measurement of WHAT! Their radii, volume, mass, force of gravity acting between them, period of orbit are some possible measurements.
