2. Carla's favorite ball is bright blue when it is outside in the direct sunlight. Inside, the ball

appears to be almost green. Why does Carla's ball seem to change colors?

A. Color is determined by the density of an object, and Carla's ball became more dense when

she went inside out of the sunlight.

B. Color is determined by the size of an object, and Carla's ball lost air while being played

with, so it was smaller when she went inside.

C. Color is determined by the wavelength of light reflected or absorbed by the object, and the

light changed when Carla went inside.

D. Color is determined by the temperature of an object, and the temperature changed when

Carla went inside out of the sunlight.
