How thick is a ream of paper?
Well, it does matter exactly what weight of paper you are using as well as whether or not it is coated... But, unless you are ready and waiting with a micrometer and need an answer down to the millimeter, you can figure on a ream of paper (500 sheets) being about 2" thick.
How long does it take for plastic bottle to decompose?
Plastic bottles can take hundreds of years to decompose in the environment due to their synthetic nature and resistance to breaking down. Factors such as sunlight, heat, and physical breakdown can contribute to the degradation process, but the full decomposition of plastic bottles is a very slow process.
When did the major tsunami happen?
Tsunamis have probably been occurring for millions of years and were most likely relatively commonplace in more violent eras in the earth's past. The first recorded tsunami probably comes from the bible - the famous flood - however science will have to prove that.
What was the deadliest tsunami?
Possibly the most dangerous tsunami occurred in Alaska, in which the highest known tsunami was recorded. Lituya Bay is a large inlet on the coast of Alaska. It is believed that an earthquake of either 7.9 or 8.3 on the Richter Scale, occurred along a nearby faultline, part of the Pacific Rim of Fire. Around 40 million cubic yards of dirt and glacier were shaken loose from a mountainside at the head of the Bay, resulting in a tsunami (series of waves), the highest of which reached over 5oo metres. Although the only witnesses to the event were people in a couple of fishing boats, the height was able to be determined by scientists finding the high water mark, where the water reached its highest point on the nearby land.
