巴布亚新几内亚有许多种类的蛇，其中一些是危险的:

这些物种中有任何一种是外来的，还是都是本土的?或者，因为这可能是一个模糊的界限，让我更准确地表达:这个岛上的任何一种蛇，自1800年以来到达吗?< / p >
积雨云的顶部通常约为40000英尺，高度可超过60000英尺，分别在245英里或300英里外都能看到。 from 你能在多远的地方看到雷雨?
我的疯狂的表弟说，在300英里的地方，他说他不能看到这个云的形成——也许只是它的顶部——因为地球曲率(距离:300英里-曲线在视线以下11.3618英里(也是59990.14英尺)。我肯定他错了。但这是合乎逻辑的，地球曲率计算是合法的
When speaking about furniture, you use width, depth, and height, but depth is confusing, because in this context it would be the opposite of height.
我正在接受遥感。我偶然看到一篇论文，他们使用地形资源信息管理(TRIM)的阴影浮雕模型来进行丘陵阴影。但是，它和QGIS/ArcGIS中可以应用于DEM的hillshade函数是一样的吗?如果我有来自两种方法(TRIM和GIS)的图像，我会看到相同的图像吗?
您的回复将不胜感激
This image, from a Reuters article, shows people on Pingtan Island in Fujian province, mainland China and is ambiguous. Are those islands on the far horizon (circled) the Taiwan main island or is it the Kinmen Islands (also Taiwan's territory)?
So are these hills I'm seeing 100 km out to sea or only 10 km?
Henrik Meinander著的《芬兰历史》
在加粗的句子中，作者说“古斯塔夫·瓦萨在万达建立了一座城市”;译者(把这本书从瑞典语翻译过来的)加上了“流”这个词;括号里。原文中没有“流”这个词。当我谷歌它，我发现Vandaforsen在维基百科。但是这个维基百科页面没有英文版本，所以我无法得出关于这个地方(Vandaforsen)的地理类别的结论。我不知道它是一条小溪的名字，一个城市的名字，还是什么?< / p >
Is there any special meaning in the separation of the "Vanda" and "fors"? In the original text also these words are separated.
When I translated the word "fors" form Swedish I have found that one of its meanings is "stream". But I am not sure whether or not a city can be founded at a stream? It that possible?
Ultimately my question is what does separated "Vanda fors" mean and is its meaning any different from "Vandaforsen"? And what is the geographical category of the place called "Vandaforsen"?
根据Wikipedia，排水分水岭是两个流域之间的边界。然而，实际上不能确定流入它的水将继续流进分叉的哪一臂。因此，分岔上游的小溪的整个流域既不能说属于太平洋盆地，也不能说属于北极盆地，它在大陆分水岭中形成了某种缺口。排水分界常被用于追踪政治、经济或其他重要性的边界。在这种情况下如何追踪分歧有什么惯例吗?
有哪些不同的处理方法?例如，大陆分水岭以及阿尔伯塔/不列颠哥伦比亚省的边界似乎沿着未定义区域的西部边界进行追溯，实际上该区域属于阿尔伯塔。
历史上有没有这样的故事，这些未定义的排水划分部分导致了关于如何追踪边界的争议?< / p >
He even went as far as listing the following geographical proportions by the numbers:
- Land=12% of the planet's surface
- Shallow seas=13% of the planet's surface
- Deep seas (1-4 kilometers deep)=40% of the planet's surface
- Abyssal plains (5-6 kilometers deep)=32% of the planet's surface
- Trenches and deeps (Over 6 kilometers deep)=3% of the planet's surface
How does this compare to Earth's oceans in real life? For this question, we'll have to disregard all land, which we pretty much know makes up 29% of the planet's surface. All I know is that the shallows make up eight percent of the Earth's oceans, but what about the deep seas, the abyssal plains and the trenches and deeps? How much of Earth's oceans do they make up?
谷歌地球上没有显示北极的冰原，而是海底的深度。这个深度是如何测量的，因为这里大部分地区终年都被冰覆盖?< / p >
For example, when I saw the Worldle for this country last February 26, I noticed the jagged coastline, and surmised that it might be of volcanic origin - a big clue given some general knowledge of the locations of the plates. (I wanted an illustrative example, but for those who want to play it from the link above, I'll refrain from spoiling it further by giving the full answer.)
I imagine that there may be other hints that can be derived from the coastline shapes or numbers of islands that would be correlated with the differences between islands in different regions of the earth. For example, if I see an atoll-like shape, I dare say it is more likely to be a Pacific island than something in the Caribbean, and having a closer first guess helps.
I'm guessing generic geographic knowledge can also be helpful for internal borders which are related to rivers and mountains, but I don't know much about general shape-related differences between such things in different regions.
To pose my question broadly: what other geographic and earth-science knowledge can you explain here or provide references to which would be both fun to study, and provide helpful background for playing Worldle?
The Professor had, among others, identified a location on the Zambezi River where the Zambezi and Chobe rivers meet +-40km upriver from the Victoria Falls, I assume close to the newly built Kazungula Bridge?
In essence the suggestion was that by the construction a 14 meter high, controllable weir, in times of flooding the river would be able to flow along the ancient route, filling Lake Liambezi, and pushing back to Maun and back via the Boteti river ultimately filling the Makgadikgadi pans. This would also mitigate he flooding downstream in Mozambique.
Building a 14m high Weir 1km wide using human and animal labour was an immense challenge 120 years ago. With modern earthmoving equipment such a task would be like building a "big farm dam" today!
My question and thinking - this would refill the MASSIVE "evaporation pans" as they were centuries ago, which would in turn raise the rainfall in especially the winter months in much of the Northern Cape, and especially Botswana moving over to Limpopo province, and ultimately raise the Average Rainfall throughout the entire Southern Africa. The thinking is that Lake Malawi and some of the lakes further north have large cloud formations late afternoons?
I assume in the 1900's many studies were done on energy rather than Water supply, with a considerably lower world populations at that time and sufficient water per capita. Thus the building of the Cahora Basa dam and Lake Kariba for Hydro Electricity
Today Climate change and its consequences are some of the biggest challenges facing Humanity, with water scarcity being the big factor in Sub-Sahara Africa.
By Ultimately raising the Rainfall in the entire Southern Africa, through the managed and controlled filling and utilization of the Natural 30 000 - 60 000 square km of evaporation pans more regularly, will this not lower the extreme temperatures (day and night temperatures due to water absorbing much of the daytime heat and releasing it during the night) and drought patterns Southern Africa has experienced, and by all predictions are bound to worsen and could become more extreme? In effect, creating a second Okavango Delta, but considerably bigger - large parts of Chobe.
A study of such a magnitude will need large amounts of research in multidisciplinary sciences, from Archaeology to Agriculture to Economics, and a much broader field of expertise - the biggest being Politics!
Could such a mammoth project not be but one small answer to a much bigger Climate Change challenge facing the Earth? (and ultimately send a bit of rain to my little piece of land in the Waterberg in the long dry winter months when we receive those dry West Winds - and fires become a serious hazard - simply by adding a bit of moisture from the vast pans Botswana are so blessed with!)
My mind has been going in circles as to the feasibility of such a mammoth, yet so cheap and easily implementable idea?
Any ideas?
这是一张漂亮可爱的亚洲地图。请注意，泪滴形状的青藏高原主宰着地图，我们要感谢印度。在过去的5000万年里，它一直在向上推进，与大陆合并。它所到之处，最大的山脉拔地而起。但是，将印度挤向亚洲是否影响了亚洲大陆其他地区的地理?如果没有印度加入亚洲，土耳其、伊朗、蒙古、中国和西伯利亚的山脉还会存在吗?更不用说有今天这么大了。< /强> < / p >
So now the question comes: Is there any place on Earth that does not have a sub-annual cyclical pattern? It seems there are some really wet tropical rainforests that don't have season, do they "really" operate the same all year long? Do the organisms living inside rainforests also show no consistent behavioral cycles (e.g., like hibernation, mating seasons in other places)?
例如:
非洲的中心位于赤道地区，然而，并没有热带雨林贯穿整个非洲。< / p >
The island of Madagascar has two different biomes
Since altitude and latitude doesn't seem to be the reason behind these anomalies, what other factors affect the biome of these places?

What I see missing from any articles on physiographic provinces, is what were the characteristics used to define any particular "physiographic province". I am a secondary teacher and need to teach and prepare curriculum about the provinces that my state falls in, so I think if I knew what kinds of characteristics geologists looked at to create each province, I'd know which characteristics to teach the students about.
Is there a list of characteristics that were used to create these groups of provinces?

I realize that the definition of what is the "peak", is somewhat arbitrary, but one definition would be the zone around where the slope flattens out, and if you go further you will always go down.
我的问题是，在这些距离较远的地方，它会破坏土壤本身和农业吗?如果是的话，会是什么样子(在什么程度上)，以及我们所说的距离是多少?< / p >
(This feels like a suspicious thing to ask, so let me just clarify that I'm asking this because this is a plot point in a book I'm writing, and I'd like to really understand what ramifications it would have outside of the specific place things are happening. I've asked related questions in other places, but I think this is the most accurate.)
Forgive me if the tags are inaccurate, I know nothing about any of this.
答案应该是43，但我一直得到65。有人能正确计算吗?

In other regions, such as the Carolinas, the climax ecosystem is for infrequent forest fires -- relatively moist forest that in absence of human intervention would burn perhaps on the order of once per century, during an unusually dry summer. This creates a forest with a lot of deadwood, moss, and so on, material that make fires very intense when they do happen.
Where is the boundary between the two? The references I have found so far, remark in general terms that western states tend to have frequent forest fires and eastern states infrequent forest fires; can it be narrowed down more precisely than that? Is there a map available showing the extent of each, or even a list of which states would fall primarily into each category? Or does reasonably correspond to something for which maps are readily available, such as Köppen climate classification?
In all cases, I'm interested in what the climates would produce in the absence of human intervention, i.e. the boundaries in temperature and rainfall conditions that would produce each kind of forest (or, in even drier conditions, no forest at all), not the changes in groundcover and fire frequency brought about by human activity.
I know Bouvet岛是相当靠南的。还有比这更南方的地方吗?< / p >
