Answer:
Looking at the sky during night is always an amazing scene. It takes our breath away, every time when we see the night sky with countless stars twinkling, full moon and planets. I always wished I reach those far planets travelling in space. The only way I can fulfill my dream is to become an astronaut. Astronaut is a person who is trained to travel in a spaceship to go to outer space. If I were an astronaut, I wish my first mission will be to the moon. However, I will have to undergo a very strict training to survive in space We all have seen the training videos of astronauts in DISCOVERY channel where they even undergo underwater training. Life in space will be different with zero gravity and so we will experience zero weight and will float freely. Wow!!!! that seems to be an exciting thing. But how we will eat and drink?

Data collected by the drilling ship Glomar Challenger confirmed that C. NONE OF THE OCEAN FLOOR IS MORE THAN 180 MILLION YEARS OLD.
Glomar Challenger began drilling on both sides of the mid-ocean ridges to gather data. The data confirmed what the sea-floor spreading hypothesis predicted. The ocean floor is youngest along the central valley of the mid-ocean ridge while the ocean floor in subduction zones or near the edges of the continents is oldest. The data has confirmed that none of the ocean floor is more than 180 million years old because the older oceanic rock will undergo subduction and go back to the earht's mantle.
