Answer:
1) Radiation from the Earth's surface is _____.
ultraviolet
short-wave
long-wave
X-ray
2) X-rays _____.
have very long wavelengths
are blocked by the ionosphere
are less dangerous than ultraviolet rays
are not emitted by the sun
Explanation:
Ultraviolet rays: They are invisible rays that are part of the energy that comes from the sun. The ultraviolet radiation that reaches the surface of the Earth is composed of two types of rays called UVA and UVB.
The answer is: Ultraviolet.
The energy of X-rays in general lies between ultraviolet radiation and naturally occurring gamma rays.
The answer is: They are less dangerous than ultraviolet rays.
Answer:
1) I don't know 2) Are blocked by the ionosphere
Explanation:
X-rays are more dangerous than ultraviolet rays. The amount of damage to the body is determined by the amount of exposure. Bone marrow, se(beep) organs, digestive system, and blood vessels are some of the body parts affected most by radiation. People who work with radiation might develop cancer. Very powerful forms of radiation or overexposure can ultimately cause death. The ionosphere absorbs all but a small amount of gamma radiation and X-ray radiation.
