This is what a scholar of mine taught us at Linköping’s University and what I have used illustrating facts about our Earth ever since:
Earth diameter Earth’s diameter is 12,756 km at the equator. (Earth’s radius is half of that)
Maximum height and maximum depth
Earth’s highest mountain, Mount Everest is ; 8848 meters high .( In other words, 8 km 848 m)
The Earth’s deep Challangerdjupet in Mariner grave, Pacific Ocean, 11034 meter deep. (In other words 11 km 34 meter)
If you on a model of Earth use 10 km = 1 mm then you will have this figure…
Man has made it to the moon is about 384,392 km (average distance) away. Few research projects have been able to get down to that depth. The reason is that the pressure increases with depth.

It was a hundred miles farther south than anyone had ever taken a sailboat. Temperatures hovered around zero degrees Fahrenheit (it’s the height of summer in the south pole) as the crew took turns hacking a heavy layer of frost that coated the ship’s deck and rails. A storm briefly sent twenty-foot waves in their path, but the surface was calm when Selma finally ran out of sea. ”We touched the ice of…
