Excellently explained ma'am.....kewp coming with new videos on geo concepts ❤

Great 🎉

Simple and clear👍

geoengineering for construction. Geoengineering for disaster prevention. Social construction for daily life and disaster prevention will protect lives from today's climate change.

A point of clarification if I may - at 2:13 you state that “Ground is cooler than air during summer and vice versa“ which is certainly true at depth but not at the ground surface, where the ground surface temperature always leads the air temperature since the ground surface is the terminus for insolation and the air temperature is a byproduct of reflected solar radiation, reradiation from the ground surface and convection from the ground to the air - the contribution of air temperature to the ground temperature is insignificant largely due to the significant disparity between the mass and energy densities of the ground and the air. This phenomenon is readily apparent on particularly hot days when the ground temperature is significantly greater than the air temperature immediately above the surface, due to the limitations of heat transfer due to convection, whereby the only way for energy transfer equilibrium to be achieved is through increased ground radiation at the higher temperature. On those particularly hot days, if we stand out in the noon day sun on bare ground, we can get cooked from both sides, and our perception always seems to indicate that air temperature is the root cause, whereas it is really the radiation, both solar and ground. The thermal gradient of the topsoil is dependent on the soil type, but in general it is relatively much steeper than that of air, and so any subsoil temperature measurements will be strongly dependent on the depth of the temperature probe, which is why the soil temperature is often measured as being less than air temperature, something that is more important to farmers than geophysicists.

Brief and precise. Thanks

So can l become geotechnical engineer when l study geography at the high school?

Thank u ma'am...u have explained in very simple language

My best wishes for you 🙏🙏 best presentation 🙏🙏 Keep sharing knowledge my friend 🎉🎉

Informative presentation, thank you!

This is great so easy to understand

Very nice video

rispect mame

Phreatic water include which of the above 3 type of soil water??

Is concrete a good conductor of heat. If the pipes are in direct contact with the ground heat exchange will be more effective. I have no research on this matter.

Thank you for your good and short explanation ...,Please upload other more videos

Thank you

Thanks for your effort and your Information please upload more videos

Really helpful. Thank you so much.

Are there any practical structures constructed with geothermal piles?

Improve your knowledge

Excellent voice clarity super

Speak louder which will be better

Interesting please do more videos🙏
