the formation of a plowpana buildup of salt in the soil to the point where it negatively affects plant growth
a minor problem that affects only a small area and is easily corrected
Answer:
the formation of a plow pana buildup of salt in the soil to the point where it negatively affects plant growth
Explanation:
Overirrigation in dry areas primarily results in a buildup of salt in the soil, also known as soil salinization, which can negatively impact plant growth.
Overirrigation in dry areas can primarily cause the buildup of salt in the soil, also known as soil salinization. This occurs as a result of the evaporation of irrigation water, which leaves behind residual salts that are not sufficiently flushed away by rainfall in dry areas. Over time, these salts accumulate and can reach levels that are harmful to the plant growth.
While it's true that overirrigation might cause other problems like high relative humidity that may indirectly impact plant health, or the potential for minor localized issues, the key problem specifically linked with overirrigation in dry areas is the buildup of salt in the soil.

The hypothesis of continental drift is used to explain an event that happened
a. two million years ago.
b. two hundred million years ago.
c. two billion years ago.
d. two hundred billion years ago.
The answer is (b) Two hundred million years ago
Answer: b. two hundred million years ago.
Continental drift is a scientific theory was developed by Alfred Wegener (1880-1930). He was a German meteorologist, who proposed the hypothesis that continents were the part of huge landmass or supercontinent about 200 million years ago. These continents got separated or splitted from their parent continent and drifted to other locations. He named the parent or supercontinent as "Pangaea" (which means "all lands" in Greek) which began to break up.
