Sad to say, the warning time that the residents of Sumatra had before the 2004 tsunami hit land was close from little to none. A rough estimation would around 15 - 30 minutes. They say that the primary cause would be that there wasn't any warning systems over the Indian Ocean at that time. Another thing, which is what most people who knew about it would point out as the real problem, is that there was no issuance of a warning in the first place. The quake was detected an hour or so before the tsunami occurred in the Pacific Tsunami Warning Centre located in Ewo, Hawaii. At that moment, the information was relayed to Australia and to the rest of the world. The question wasn't why the Centre didn't issue a warning, but why the whole world network of information didn't issue one. They say that other sophisticated data were available at that time and almost immediately since the tsunami was active.
A. Marine West Coast Climate - sunny, mild
Marine West Coast Climate is also called Oceanic. It is characterized with relatively narrow annual temperature range and features a warm (but not hot) summers and cool (but not. cold) winters.
B. Tropical wet and dry - <span>Heavy downpours of rain
</span><span>All twelve months in the tropical climate regions have mean temperatures of at least 18 °C.</span>
<span>C. Moderate Mediterranean - mild and rainy
</span>This climate<span> is known for warm to hot, dry summers and mild to cool, wet winters. </span><span>
D. Tundra - cold
</span>Tundra is the climate with largest average precipitation per season (4.5 inches.) The type of precipitation that falls in this climate<span> is mostly snow in the winter, and in the summer it is rain, with occasional snow. </span>
A radioactive element with a half-life of 1,000 years, and starting mass of 20 grams, will need 2,000 years to decrease to 5 grams.
Explanation:
The radioactive elements all have a specific half-life. Each element's half-life is well known, and they are used by scientists of numerous fields as they are excellent for determining the age of a particular item, be it or organic or non-organic nature. In this case, we have a radioactive element with a half-life of 1,000 years, and starting mass of 20 grams.
The half-life basically means that half of the mass of an element is lost during a particular period of time. For the element in question we need to find out how much time will be needed for it to decrease to 5 grams. In order to get to the result, we just need to add 1,000 years on every decrease of half of the mass:
20/2 = 10
10/2 = 5
So in 1,000 years, the element in question will decrease to 10 grams, and in further 1,000 years (2,000 cumulatively) it will decrease to 5 grams.
