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.
Meteorologists use tools like Satellites, weather balloons and automated weather stations to collect data about the weather for the purpose of weather forecast.
<h3>What is weather forecast?</h3>
Weather forecast is a way of using different geographic and scientific tools for studying the weather conditions and predict the most favorable weather conditions that may occur over a specific region.
Meteorologists use different tools, which are helpful for them to predict the weather forecast, and bring it to the public notice so that they can be aware of the activities that may or may not be undertaken during such weather conditions.
Some of the most commonly used tools by the meteorologists to collect data about the weather are satellites, weather balloons and automated weather stations. Please refer to images given below.
Hence, options A, D and E are correct that meteorologists use tools like these for the collection of data about weather and predict the weather forecast.

Answer: FOSSIL OF FISHES.
Explanation: The law of faunal succession, is based on the observation that sedimentary rock strata contain fossilized flora and fauna. These fossils succeed each other vertically in a specific, reliable order that can be identified over wide horizontal distances. According to this law, the order for animals is as follows; animals with shells; fishes; amphibians; reptiles; mammals; birds; humans.
The correct answer is letter D. Volcanism describes all the processes associated with the discharge of magma, hot fluids, ash, and gases. These specific events happen during an eruption of a volcano where hot materials come out from the core of the Earth. Volcanism is one of the many interesting studies of Earth Science.
