I think its because of the mountain ranges there in new Zealand because in Australia they have a small moutain range called the blue mountains I visited there in the 90's that day it was scorching hot and they actually ski on those mountains on new zeland ive been ski ing there twice because of my parents!
That would be normal for Australia, that whole area was an inland sea/massive salt water lakes at one point if memory serves correctly and there were actually proposed plans at one point to i kid you not to dig a connection from the sea to that area and a few other places in Australia to bring more greenery to the interior...
Hey Jack, fun fact when the sea level decreases, the original land gets yellow like a desert, but at the end, the land that was originally water becomes green like grass!
that is incorrect. if the water disappeared every single ocean would leave behind all the salt that was in the water and those areas would become a very salty and hot desert
This video really just connects all the geography knowledge we know, and I think the rising sea level does way more with that than the lowering sea level. You can immediately see the Netherlands disappear into oblivion, but then you see the western America mountain ranges from Alaska to Northern Chile and the mountain ranges around the "Roof of the World" in Asia being the last remaining places. As I said, this connects the separate knowledge that we possess, and if you dive into it deeply, this video tells you way more about geography than it'd seem at the first glance. Edit: I see you guys arguing heavily in the reply section of the pinned comment. I will explain as best as I can here, because more people will see it. Jack knows the Himalayas is the mountain range with the highest mountain, Everest, at 8848m. He did not know that Kathmandu was the capital of Nepal prior to this video coming out and all the comments storming in. That is not a reason to be mad at him. Even though he's learnt a lot of stuff in the past 2 years about geography, geography is learnt over time, and he hasn't studied it properly for that long from what I'm aware of. As he would agree, he is willing to learn from our comments, but we don't have to storm in and send hate comments at Jack. As for giving you guys more information about the topic, I will try to give you guys the information I learnt from studying for a competition which consisted of knowledge about Asia. I can't say I'm an expert at geography either, but I think this will help you better understand. The tallest places on earth are located around the Pamir and Tibet plateaus, which are the tallest plateaus in the world. They are mostly located in Tajikistan and China respectively. Although the Himalayan mountains are the tallest, there are a lot of mountain ranges that are also very tall around them. The way I was taught them was by two rows of mountain ranges from the Pamir plateau. One going all the way up to north-eastern Russia, and the other going to south-east China. The latter one contains the Himalayan mountains. To the west of the Pamir plateau are the Hindukush mountains. I don't know the English names for the mountains in the rows that I mentioned, but you can always find them on the internet, and use my comment as a guide to learn them. I just realized the edit is longer than the original comment I made :) I will end the way I started: Don't send hate to Jack, just send him information that will help him learn more aspects of geography.
I always thought Ireland was really mountainous terrain because everywhere you go there's mountains and hills but ig we're no where near mountainous as other places
To me as an archaeologist the lowering sea levels are the most significant because it gives an image of the world during the last Ice Age, when sea levels were lower. Of course it wasn't so exaggerated but early on we can see can see Doggerland, Beringia, Sahul, Sunda etc, and it shoes how the world looked at the time humanity started reaching the very edges of it. Meanwhile the rising sea levels has little significance beyond flooding risks and illustrating melting ice caps, which would only result in... a 10m rise, I think?
The Netherlands actually has a strong defense system against rising sea level and makes sure that the water goes through the country instead of over it
i think its the highest mountain, if im not mistaken there is a "taller" mountain in the area of hawaii but part of it is under water so its not higher up

"oh there's already a hole in australia!" that is a lake, it was already there (just got a bit bigger) it's actually a shame most people outside Australia don't know about Kati Thanda-Lake Eyre, because most world maps don't include it

That "Oh look at that, the UK and France are connected" is Doggerland, a part of Europe that was inhabited until a massive Tsunami flooded it. This is why British and French fishermen often get stone age artifacts in their nets. Edit: Shouldn't have paused the video.
2:48 bro called Kathmandu China :skull: Jack, those are the central Asian mountain ranges that include the Karakoram, Hindu-Kush, Himalayas, Pamir, and Tien Shan ranges, as well as the great Tibetan plateau. These ranges span across Uzbekistan, Kyrgystan, Kazakhstan, Tajikistan, Pakistan, India, Nepal, Bhutan, China and Myanmar.
@@Melvin-14 what u just said is false, from the current knowledge the Mariana Trench is the deepest point in the ocean, but there’s a 93% chance that it isn’t the deepest, as only 7% of the ocean has been explored
@@Melvin-14 and, that with satellites don’t make sense, as a satellite is something that orbits a planet, star or black hole, anything from a man made satellite to a moon or planet or a star, having a satellite having sent sightings from all oceans on planet earth doesn’t make sense.
You didn’t notice where it became possible to walk around the world.
