Continental Rise: Definition & Facts

Each of the pictured bottles has a relatively short description and explanation including estimated dates or date ranges for that type bottle and links to other view pictures of the bottle. Additional links to images of similar bottles are also frequently included. The array of references used to support the conclusions and estimates found here – including the listed dating ranges – are noted. Additional information and estimates are based on the empirical observations of the author over 50 years of experience; this is often but not always noted.

Various terminology is used in the descriptions that may be unfamiliar if you have not studied other pages on this site. If a term is unfamiliar, first check the Bottle Glossary page for an explanation or definition.

Older tires are substantially more likely to fail than newer ones. This is because tires are made mostly of rubber, and rubber degrades with age. Sunlight, heat, ice, and general wear and tear can accelerate the breakdown of a tire. Once a tire begins to break down, it becomes more likely to fail in the form of a tread separation—often at highway speeds, when the failure is most likely to cause catastrophic injuries or death. For most tires, this expiration date should be six years from the date of manufacture.

Tires age dangerously because of a chemical process commonly referred to as oxidation, which simply means that as the tire components are exposed to oxygen, the oxygen particles cause the flexible components of a tire to harden and become brittle. Over time, the tire will simply fall apart under normal stress, just like an old rubber band. Because this process occurs naturally, it does not matter if a tire is being used, stored as a spare, or simply waiting on a store shelf for an unsuspecting consumer.

Tire tread life has quadrupled over the last forty years and some currently sold tires promise , miles of tread life. As tread life becomes less of a factor in the service life of a tire, oxidation becomes a more serious concern— particularly in hotter climates, like Texas, Florida, Georgia, and Louisiana which are routinely the hottest states in the United States. These studies conclusively conclude the following: Tires begin to weaken and fall apart as they age.

The tire aging process happens regardless of whether a tire is on a vehicle or in a temperature-controlled room.

Most of the time, the tin will not have a date marked anywhere on it, and that’s where some detective work on your part is required. Dating tins isn’t difficult to do, though it may involve some of your time. This process can turn out to be both fun and personally rewarding. The following information can be used to help document the age of your tins.

Dating – Rubidium–strontium method: The radioactive decay of rubidium (87Rb) to strontium (87Sr) was the first widely used dating system that utilized the isochron method. Rubidium is a relatively abundant trace element in Earth’s crust and can be found in many common rock-forming minerals in which it substitutes for the major element potassium.

Like this lesson Share If you had to guess, would you think a continental rise is a mountain in the middle of a continent? It’s a fair assumption, but not a correct one. Here you will find out what the continental rise is, where they’re found, and what creates them. What is the Continental Rise? There’s a surprising place where perhaps half of the world’s sediments are settling. These materials that are broken down by weathering and then carried by rivers and streams aren’t always ending up in stream beds, river deltas or flood zones.

Instead, many of them are ending up in a place that’s not on land at all.

In the footsteps of Graham Greene at the Continental Saigon In the footsteps of Graham Greene at the Continental Saigon The famed hotel may no longer be grand, but it has old-world charm in buckets. Just don’t steal the furniture By Adrian Mourby 30 July, The Continental Saigon is atmospheric, grim, fascinating and hilarious — all at the same time. It was here first. It opened in opposite the opera house in what was known then as Place Garnier. The first movie — made in — starred Audie Murphy as the titular American while Michael Redgrave played Thomas Fowler, the journalist who connives at his assassination.

Toast with vegemite Prior to the Second World War and the widespread adoption of household refrigerators, the traditional Australian breakfast consisted of grilled steaks and fried eggs, mainly because of the ready availability of beefsteak during that period. Although this is still eaten in the bush, very few urban Australians today would recall this breakfast format—but the steak-and-eggs breakfast has survived as the customary pre-landing breakfast of the United States Marine Corps , due to the Marines having copied it from Australian soldiers when the two countries campaigned together during the Pacific War.

Fruit is also common at breakfast, either on the cereal or eaten separately. Breakfast habits differ more between age groups or families than between cities. Leftover fish or meat from the previous night’s meal may be served as well. The range of processed breakfast cereals is vast and children are more likely to eat those that contain added sugar. Porridge is typically served with milk, sugar, fruit or yogurt.

Sliced bread which has been toasted and topped with preserves or spreads is a common alternative breakfast. Eating breakfast at a restaurant was unheard of until the s; however cafes which serve breakfast until midday or all day are now common. Other common menu items are:

The drift theory[ edit ] The rifting of Pangea. As first formulated, the drift theory was that the continents had once been joined together in a single large continent Pangaea which then split into the modern continents, which then drifted into their current positions. We now know that this was only one of a series of similar events by which continents have alternately been pushed together and pulled apart.

The animation to the right shows the splitting apart of Pangaea. When the drift theory was first proposed, the “drifters”, as they were called, had no idea how the continents could have moved, and such proposals as they came up with were contrary to reason and evidence as was pointed out by their opponents, the “fixists”.

Tire Date Code Related Categories: Tire Tech Information – Determining the Age of a Tire …Tire Identification Number The use of a partial Tire Identification Number on the one sidewall shown above reduces the risk of injury to the mold technician that would have to install the weekly date code on the top sidewall portion of a hot tire mold. Prior to , the tire industry assumed that a tire would not be in service longer than ten years.

As such, the date code consists of only three digits, two for the week and one for the year. For more information, read “Determining the Age of a Tire.
