The moon looks blood red during a total lunar eclipse because some of the sunlight passes through Earth’s atmosphere to reach the moon. As the white light breaks up while passing through the atmosphere, most of its blue-colored wavelengths are absorbed and scattered. The remaining red wavelengths light up the moon in blood-red color. Which of the following statements do not support the assertion of the above-given statement? I: The moon looks blood red during a total lunar eclipse as the white light breaks up due to the Earth's atmosphere where most of its red-colored wavelengths are absorbed. II: The moon looks blood red during a total lunar eclipse as the earth blocks the white light to travel to the moon.
