beams toward Earth is deflected by the beams toward Earth is deflected by the outer atmosphere and scattered back into outer atmosphere and scattered back into space. The rest reaches the planet’s space. The rest reaches the planet’s surface and is reflected upward again as a surface and is reflected upward again as a type of slow-moving energy called infrared type of slow-moving energy called infrared radiation. radiation.
