How long does it take for a geyser to form

50-100 minutes

Explanation:

The process begins again. In some small geysers, the eruption process can take just a few minutes. In larger geysers, it can take days. The most famous geyser in the United States, Yellowstone National Park's Old Faithful, erupts about every 50-100 minutes.

Geyser activity, like all hot spring activity, is caused by surface water gradually seeping down through the ground until it meets rock heated by magma. The geothermally heated water then rises back toward the surface by convection through porous and fractured rocks.

Explanation:

no

explanation:

since the earth is flattened at the poles and bulges at the equator, geodesy represents the figure of the earth as an oblate spheroid. the oblate spheroid, or oblate ellipsoid, is an ellipsoid of revolution obtained by rotating an ellipse about its shorter axis.
