live in an environment, such as Mercury's, lacking an

                    atmosphere.

                          There is an atmosphere on the planet Venus.

                    Because the pressure on Venus is ninety times greater
                    than the pressure of Earth's atmosphere, it does not

                    provide suitable conditions for human life. From this

                    information, we understand that no life can exist on

                    the planet Venus since under its great pressure all liv-

                    ing things would be crushed.

                          Let us go over the points we made earlier: The

                    atmosphere is one of the essentials for life on Earth.

                    The atmosphere has many functions, some of which
      84
                    have been briefly explained above. As you will remem-
                    ber, one of these is the importance of the gases that

                    make up the atmosphere for human life. If the atmos-

                    phere did not exist, living things could not breathe,

                    and thus there would be no life on Earth.

                          Another function of the atmosphere is to protect

                    our Earth against threats from outer space, such as

                    meteors. The atmosphere prevents meteors from

                    falling on Earth and causing harm.

                          The atmosphere also blocks harmful radiation
                    coming from space. Thanks to the atmosphere, only 7

                    percent of this harmful radiation reaches Earth. Here is
