15 Amazing Facts To Know About Science
--
Science is a fascinating subject with many amazing things to learn and discover. Thankfully you’ve got a lot of time to research, the average human only sleeps for about 35% of the day compared to 80% for armadillos and sloths, now that’s lazy!
However, Here Are 15 Amazing Facts To Know About Science.
- Gravity on the moon is a sixth of what it is on Earth. Someone who weighs 150 pounds (68 kg) on this planet moves the scales at only 25 pounds (11 kg) on the moon. Its gravity is so much lower because the moon is just 1 percent the mass of Earth. Your weight on the various planets would vary greatly. If you could stand on Jupiter, you’d weigh more than twice as much.
2. Earth’s oxygen is produced by the ocean. Ever stopped to think where oxygen comes from? Your first thought may be a rainforest, but marine organisms take the bait. Plankton, seaweed, and other photosynthesizers produce over half of the world’s oxygen.
3. The Eiffel Tower can be 15 cm taller during the summer. When a substance is heated up, its particles move more and it takes up a larger volume — this is known as thermal expansion. Conversely, a drop in temperature causes it to contract again. The mercury level inside a thermometer, for example, rises and falls as the mercury’s volume changes with the ambient temperature. This effect is most dramatic in gases but occurs in liquids and solids such as iron too. For this reason, large structures such as bridges are built with expansion joints which allow them some leeway to expand and contract without causing any damage.
4. The Earth appears to have a whole new underground continent called Zealandia. The discovery itself isn’t new — some geologists have been arguing for its existence for many years. However…
