Question

You are inside a hot air balloon floating at 500 m above the ground. What would you say about the view of the Earth’s surface as you see it?

Options

• square

• rectangular

• circular

• triangular

Answer 1

Circular

Explanation:

The horizon is at the same distance in every direction, so the visible patch of Earth’s surface from a balloon is roughly circular around you. At 500 m, the horizon still forms a near-circle.
