Answer:

b less dense and thicker under the continents than under the oceans

Explanation:

  • <em>Oceanic crust </em>is found under the ocean, it's about 6 kilometers thick and is destroyed in subduction zones just like the continental crust. It's composed of several layers and it differs from continental crust because it's thinner, denser, younger and with a different chemical composition (olivine, pyroxene, and amphibole).
  • <em>Continental crust</em> is thicker (100 kilometers) and less dense than oceanic crust, it resists subduction and its age is 30 times the average of the ocean's age.

Considering this information we can conclude that the correct asnwer is: b less dense and thicker under the continents than under the oceans.

I hope you find this information useful and interesting! Good luck!

Causes and the effects of the fohn winds on the environment<br>​
Ket [755]

Explanation:

There are four known causes of the foehn warming and drying effect.[1] These mechanisms often act together, with their contributions varying depending on the size and shape of the mountain barrier and on the meteorological conditions, such as the upstream wind speed, temperature and humidity.

*Condensation and precipitation

، Isentropic draw-down

*Mechanical mixing

*Radiative warming

Winds of this type are also called "snow-eaters" for their ability to make snow and ice melt or sublimate rapidly. This is a result not only of the warmth of foehn air, but also its low relative humidity. Accordingly, foehn winds are known to contribute to the disintegration of ice shelves in the polar regions.[7]

Effect :

Foehn winds are notorious among mountaineers in the Alps, especially those climbing the Eiger, for whom the winds add further difficulty in ascending an already difficult peak.

They are also associated with the rapid spread of wildfires, making some regions which experience these winds particularly fire-prone.
