GROUNDWATER MINING: What happens when an aquifer runs out of water ?
Groundwater minining consists in extracting water from the ground at a faster rate than the water supply can be recharged. The most immediate consequence of this overxploitation of a reservoir is that it will sooner or later run out of water. But that is not all, groundwater mining has more far reaching and sometimes even surpising consequences. In this short video we will first discuss aquifers and look at how water arrives and moves underground. We will then look at how grounwater mining affects aquifers, but also the flow of water flowing in rivers and the very ground below our fields or cities. After watching this video you will understand why it's important to manage our groundwater ...

HOW DO ROCKS FORM AND WHAT CAN THEY TELL US? - The rock cycle
Просмотров 1,5 тыс.Год назад
In this video you will learn that rocks can be formed in three different ways, and correspondingly there are three different types of rocks: magmatic rocks, sedimentary rocks and metamorphic rocks. You will also learn that rocks are continuously transformed from one type to another in a set of processes know as the rock cycle. Finally, we will also see how, by observing the rocks, we can learn ...
HOW CAN WE TELL WHAT THE CLIMATE WAS LIKE IN THE PAST ? - Tree rings and oxygen isotopes
Просмотров 3,7 тыс.Год назад
How can scientists tell what the climate was like before the existence of thermometers and before people started recording temperatures ? In this video we explore some of the ways in which paleoclimatologists are able to use proxy observations such as tree rings and oxygen isotopes to reconstruct the climate of the past.

GLOBAL ATMOSPHERIC CIRCULATION
Просмотров 67 тыс.3 года назад
In this video we will look at why and how winds move around the planet. We will learn about the different cells that compose the global circulation pattern. Moreover, we will explain how the Coriolis effect deviates air masses travelling towards the Equator or the Poles to generate the Trade winds and the Prevailing Westerlies.

In this video, we will discuss what tectonic plates are and why they move. We will also look at what happens when two plates moving in different directions meet, introducing the concepts of convergent, divergent and transform plate boundary. We will also briefly explain what lithosphere and asthenosphere are and take a look at mantle convection and what it means. Image credits: Map of the seafl...
How do rivers form? (surface and groundwater flow)
Просмотров 315 тыс.3 года назад
In this video, we will look into why water flows in rivers long after the rain has stopped. Where does the water come from? We will learn that rivers are fed from surface runoff, as water flows over the surface during, or shortly after it rains, but also through their beds, by groundwater which infiltrates through the soil and is stored in the pores of rocks in large underground reservoirs call...
What are Earth's rheological layers?
Просмотров 3,2 тыс.3 года назад
This video describes Earth's rheological layers, the lithosphere, asthenosphere, mesosphere, outer core and inner core. We will explain that with the exception or the outer core, which is liquid, most of our planet is solid because of the very high pressure in the Earth's interior prevents the rocks from melting. We will then concentrate on the difference in rheological behaviour between the li...
Thank you miss🙌💯
made it too compilcated to understand untill 04:20 🤭
Great explanation! Thank you!
balso, why does the warm air not rise and fill the space up when the other warm air rises at the equator
quick question: doesn't air come from all sides then, not just 2 sides because the surface of earth is 2D? it's like closing in on all sides. And the water bucket example is 3D but the same applies: it's all directions? everything else is flawless
The quraan 1400 years ago states that some rocks form rivers. SubhanAllah .
Thank you. This really helps a lot in advance learning. So simple and wasy to understand.
This channel is referred to me by Gemini.
So clearly explained! Wonderful. Thanks. I learnt a lot.
Thank you for the video. It was very helpful and interesting
Ma'am this explanation was very detailed and well presented.
Tree rings are dodgy as 'evidence'. Frankly anyone who believes the world is now hotter than at any time for 120,000 years needs their head examined.
Love from India 🇮🇳🧡🤍💚💙 INDIA 🔛🔝👯♀️💃🕺🏼
When you maintain a curiosity, you will never be bored
Rani abakka was also the best
This is one of the examples which made me choose Science And now …..☠️
rivers receive VERY LITTLE water from the "water table" 99% of the water comes from the snow peaks and ground runoff, the fact this video spent so much time talking about the water table is why people are so stupid.
Dear Philipp, it really depends... some rivers are indeed in large part fed by glaciers and runoff, but there are many others that are not... First of all, many rivers do not originate directly from glaciers but from springs (a spring is where the water table reaches the surface), secondly the entire premise of the video is to discuss why is there water in the river even when there is no surface runoff.... Finally, I am not sure what river you are referring to as fed 99% by snow and surface runnoff, but as far as I know, they are not very common : even in the Himalayas glaciers provide, at peak season, only a maximum of 80% of the water in the river (see Rowan, A. V. et al., Geological society spec. pub. , 2014) and, as another example, the Upper Colorado River (which receives plenty of snowmelt and runoff), has been found to have roughly 50% contribution from baseflow (see Rumsey et al, Journal of Hydrology, 2015) . IN ANY CASE, lowering of the water table has major consequences to the amount of freshwater available in rivers and understanding the relationship between ground and surface water is ESSENTIAL to properly manage our water resources and more generally to understand the water cycle . Failing to do so would be , maybe not quite stupid (I actually do not believe people are generally stupid), but let's say ignorant ?
Bro I though shawty was taking a piss in the beginning
I love your channel so much, I just watched all of your videos. I'm looking forward for the next one :)
With all accessories
Any bts army here
Wonderful 🎉
This exact scientific phenomenon has been mentioned in the Quran 1400+ years ago Then your hearts became hardened after that, being like stones or even harder. For indeed, there are stones from which rivers burst forth, and there are some of them that split open and water comes out, and there are some of them that fall down for fear of Allah. And Allah is not unaware of what you do. Quran 2:74 Surah Al-Baqarah Ayat 74 Why then do you not believe? For indeed, it is not eyes that are blinded, but blinded are the hearts which are within the breasts.
Wow perfect explanation 🎉🎉 thank you
Any DMs here making a campaign map? Lol
I'm a player actually and was thinking about if I ever become a DM I want to be geographically realistic lol
Thank you ma'am ❤
why french
Thanks
You must love Jehovah your God with all your heart and with all your soul and with all your mind and with all your strength. You must love your neighbor as yourself. Jesus the Anointed is Lord! Repent and be baptized and believe the Evangelism.
Thank you so much for this awesome explanation 😊👍🏻✨
Nice explanation short and effective
Ay ngeke vumani ukuth anazi ayikho lento echazwa la
The English word for when you call 'magmatic' rocks, we call "igneous" rocks. If this was fixed, I would use this video in my lessons. Please let me know if you ever fix it, because that one word is a big deal. I love all of the other details in this video though!
Hello Sarah, thank you for your nice comment. Actually igneous or magmatic can be used interchangeably. For historical reasons igneous used to be more common (and I believe is still possibly most common in the States) but more recently the trend (at least in scientific papers) is to prefer the word magmatic. The reason why I personally also prefer magmatic to igneous is that it makes a direct link to the rocks origin (and the parallel with the other types of rocks , e.g. sediments turn into sedimentary rocks, magma turns into magmatic rocks). By the way, similarly the words plutonic and volcanic (which used to be more common and can probably still find in textbook along with the word igneous) are being replaced with the words intrusive and extrusive ( which make more sense because not all intrusive rocks are associated with plutons and not all extrusive rocks are necessarily linked to a volcano).
❤️👏
best explanation
Imagine mankind having the ability to just observe these things. No classroom, no teacher, no grading and memorization system that keeps the student anxious instead of enjoying the process of learning.
Thank you..i get a fact..
Explain in flat earth term 😅😂😂
Air does air things because it feels like it
@@JayFromWalmark 🤫🤫 shhh... Those who believe in flat earth are roaming around us . Stay alert 🫡😁
Wonderful, i like this, thanks for beautiful explanation. ❤
Dont do drugs bahaha
I'm surprised that you didn't mention *springs*. They play a very important part in how rivers form - in fact, the "source" of many rivers is a spring (or sometimes a number of springs).
Very understandable..Thank You..
perfect
Compaction, that's what will happen in Antarctica now that it has basically completely melted. All the artifacts they're searching for now will be crushed. No frozen water to hold the heavy rocks the historical evidence is burried in from collapsing. Leave it to those who with all their riches and power to tear Antarctica to pieces in their selfish quest for Hidden Treasures. They know very well why and how "Global Warming" has happened.
amazing explanation🥵❤
Great video, was exactly looking for this.
aquifers are basically just deposited rainwater
Thank you so much for this great explanation! your easy to understand wording and graphics has really helped me understand this topic for my alevels!
Thanks akkaa Saved My LIFE!!!
