O que acontece quando uma área é irrigada em excesso ?

La sur-irrigation peut provoquer un drainage profond de la montée des nappes phréatiques qui peut conduire à des problèmes de salinité d'irrigation nécessitant un contrôle de l'eau par une certaine forme de drainage des terres souterraines. Cependant, si le le sol est sous irrigué, il donne un mauvais contrôle de la salinité du sol, ce qui entraîne une augmentation de la salinité du sol avec une accumulation conséquente de sels toxiques à la surface du sol dans les zones à évaporation élevée. Cela nécessite soit une lixiviation pour éliminer ces sels et une méthode de drainage pour évacuer les sels. L'irrigation avec de l'eau saline ou riche en sodium peut endommager la structure du sol en raison de la formation d'alcaline.
The answer is coastline lowlands. In Japan, there are 6,800 islands in its archipelago and 4 main islands.

Answer:
when there is a transfer of heat from one part to another due to a change in temperature between them is called heat.
Explanation:
when there is a transfer of heat from one part to another due to a change in temperature between them is called heat.
Heat energy is due to movement energy particles from one body to another. There are various ways through which heat can be transfer. some of them are listed below
conduction -
convection
radiation
Explanation:
As the distance of the pole is less than the distance of the equator from the center of the earth, the force of attraction is higher on the body at poles than at the equator. Hence the weight of a body is greater at pole than at the equator.
Answer:
Jupiter's moons are orbiting Jupiter while Jupiter's position doesn't change. Each day, there are some moons visible, while others are hidden behind Jupiter.
