Question

what would happen if earth had no axial tilt? *
more extreme weather
constant climate everywhere
faster orbit around the sun
increased solar radiation

Explanation:

The Earth's axial tilt causes seasons. Without it, there would be no seasonal - related climate changes in a region over the course of a year, leading to a more constant climate everywhere. Extreme weather is not directly related to axial tilt absence. The orbit speed around the Sun is determined by gravitational forces and not axial tilt. Axial tilt does not directly affect the total amount of solar radiation received.

Answer:

B. Constant climate everywhere
