The Planet Earth

This 11-question quiz looks at the planet we live on, covering its structure and a few key numbers.

You will see fill-in-the-blank and true or false items, with questions such as What is the axial tilt value of Earth? and What is the name of the deepest location in the world's oceans?.

A detail that surprises some students is that Earth is not a perfect sphere; it bulges slightly at the equator, a shape known as an oblate spheroid.

You will also work out just how much of the surface is water.
