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 resources sustainably in order to avoid negative economic, environmental and social repercussions.

HOW DO ROCKS FORM AND WHAT CAN THEY TELL US? - The rock cycle
มุมมอง 2Kปีที่แล้ว
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
มุมมอง 5K2 ปีที่แล้ว
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.
WHY ARE CITIES HOTTER THAN THE COUNTRYSIDE? - The urban heat island effect
มุมมอง 15K2 ปีที่แล้ว
Cities can be several degrees warmer that their surroundings. What causes this difference in temperature? Find out in this video #weather #climate #earthscience
WHAT ARE FOEHN WINDS?
มุมมอง 35K3 ปีที่แล้ว
In this short video, we will learn what foehn winds are and how they form. #föhn #santa ana #chinook #loo #adiabatic lapse rate
GLOBAL ATMOSPHERIC CIRCULATION
มุมมอง 85K3 ปีที่แล้ว
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.
WEATHER AND CLIMATE - what is the difference?
มุมมอง 1.7K3 ปีที่แล้ว
In this video, we will explain the difference between weather and climate, and what causes weather and climate to change. We will also discuss the relationship between changing weather and climate change.
Plate tectonics
มุมมอง 8103 ปีที่แล้ว
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)
มุมมอง 358K3 ปีที่แล้ว
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?
มุมมอง 3.7K3 ปีที่แล้ว
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...

    Well, comparison between tree ring data and ice core data show that ice core data better correspond to measured data. The "hockey stick professor" only used tree ring data from a few selected trees to get rid of the roman and medivial warm period.

    Why arent the origins of river shown with actual satellite footage instead of diagrams. Even "underwater" rivers could be mapped with infrared or thermal visual aids until the rivee source is seen

    balso, why does the warm air not rise and fill the space up when the other warm air rises at the equator

  • @candyplayzrblx3728
    @candyplayzrblx3728 4 หลายเดือนก่อน

    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

    • @amberhardy8233

      This is true when the rising air is in one spot, such as a tropical cyclone.

    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.
