As lime dissolves in the soil, calcium (Ca) moves to the surface of soil particles, replacing the acidity. The acidity reacts with the carbonate (CO 3) to form carbon dioxide (CO 2) and water (H 2 O). The result is a soil that is less acidic (has a higher pH).
The Japanese began to colonize the Philippines because they were  running out of space and resources. Their country is four big  islands that were recently formed by volcano â¦ es, meaning that they  have limited mineral and metal resources.
The Negritos crossed prehistoric land or ice to settle in the islands' land. Many groups of Austronesian people began to come to the Philippines in the first millennium, pushing the aboriginal population into the interior or perhaps absorbing them through intermarriage. Chinese merchants arrived in the 8th century.
