What type of radiation causes summer tans and sunburns?

• infrared rays

• x-rays

• ultraviolet rays

• gamma rays

Why are living things on dry land not severely damaged by ultraviolet radiation?

• UV light is blocked by buildings

• UV light is absorbed by the atmosphere

• UV light is reflected by land

• UV light is invisible
