The International Date Line is where the date changes, not the boundary between night and day. There is no name for that boundary, because it always moves.
The Mohorovicic Discontinuity is the boundary between the crust and the mantle, where seismic waves change velocity.

A property boundary is where one lot of land ends and another begins. Most property owners have fences built along the boundaries of their property, but sometimes the only way to know for sure the location of a property boundary is to hire a surveyor.

He didnt just discover 'a boundary' between mantle and outer core. He provided the first reasonable accounting of Earths interior (proved the thought that the earth was in layers and not just a homogenous planet). He was also the first to estimate the temperature and physical properties of the earths core, which is why the boundary is called after him. He first discovered the layers through seismic waves from earthquakes, realising they had different magnitudes and intensity because they must have had to go through layers before reaching the surface as well as depending where the epicentre is.
it depends on the deepth
The mesohere,the boundary between the Thermosphere and Mesosphere, is technically the coldest place on Earth, with a temperature of −100 degrees Celsius (−148.0 degrees fahrenheit; 173.1 K).

Earths atmosphere? 300 miles. There is no definite boundary.
