Depths and Heights: Earth vs Mars

Numbers often become very difficult to comprehend when they get incredibly large. If I told you that the tallest mountain on Mars, Olympus Mons, was 27,000 metres tall or that the deepest Ocean on Earth, the Mariana Trench was 11,000 metres deep – you would probably think ‘wow!’, without really being able to comprehend the magnitude of that.

Well Olympus Mons, at 27,000 metres tall – is very nearly three times as large as Mount Everest here on Earth. That is jaw-droppingly enormous… It really is.
