  • If you smoothened out the earth, how high would the water level be?

    Jump

  • Tides are in the dimension of metres, the global ocean would be kilometres deep.

    Edit: also, due to earth's rotation, the ocean would be slightly deeper around the equator than at the poles.

  • As @huquad@lemmy.ml pointed out, @LodeMike@lemmy.today had an error in their calculation (radius squared instead of cubed). Their corrected result, 1.7 mi also equals 2.7 km (rounding to 3 km is a bit rough).

  • No, there are about 1.4 billion cubic kilometres of water on earth (V_w ≈ 1.4·10⁹ km³). Earth's diameter is D_E ≈ 12750 km. The volume of the relatively thin shell of water is approximately V_w ≈ π(D_E)² t. Inserting yields t ≈ V_w/(π(D_E)²) = 1.4·10⁹ km³/(π (12750 km)²) ≈ 2.74 km.

  • In Germany, in winter it's also dark at 8:00 AM CET (standard time) when the pupils go to school. With DST it would then become dark at about 17:00 instead of 16:00.

    Edit: Actually, school starts at 8:00, so the pupils are on their way already earlier.

  • only possible with direct representation and without regional representation

    Multi party systems work also with regional representation if both approaches, regional and federal, are mixed.

  • Walking just 4,000 daily steps once a week cuts risk of early death in older people

    Jump

  • I think the same (like its German counterpart), as the journalists of the Guardian are probably native speakers who should know, but the reactions of other lemmings seems to suggest that the other meaning is relatively uncommon.

  • Does 'daily' always mean every day or can it also mean per day?
