Answer 1

Hainan Island is beautiful and rich, the historical glorious island. In the geological period, Hainan Island unites originally with the China mainland, lives the islands which breaks falls forms. when eopaleozoic (before being 570,000,000, - 440,000,000), the Leizhou Peninsula and the Hainan Island area was a subsidence belt. East Gary the orogenesis causes the thunder fine jade area to rise the land, north of forms the East to a series of break belt of folded strata primarily, caused the eopaleozoic deposition the stratum to have the qualitative change. (Was before the late Paleozoic Era 440,000,000 - 230,000,000), Hainan Island landmass relative stabilization. But the Indo-Chinese movement urges the magmatic activity to be intense, forms now the Hainan Island widespread distribution granite body, constituted the mountainous region, also built Hainan Island's foundation. Afterward yenshan movement and the Himalayas movement caused this granite dome to have the intense break, formed several big things to the fault zone, caused south of the break about 2/3 region liftings, was called Hainan anticlinal bowing, and since more than 100,000,000 years have been rising; North of the break occurs undercuts, is called the thunder fine jade to be hollow. However, before the Quaternary Period before (2,500,000), Hainan Island and the Leizhou Peninsula also links in the same place, is in the geologic structure the China land parcel extends the part. (Was before probably the pleistocene epoch 2,500,000 - the l 0.5 years ago) the intermediate stage, as a result of the volcanic activity, between the Leizhou Peninsula and Hainan Island occurred mediates falls, turned the Qiongzhou haixia, only then caused Hainan Island and the mainland separates. The later sea level rises and falls many times causes Hainan Island and the mainland separates many times and connected, finished to the quaternary ice age, the sea level large scale rise, only then forms the Qiongzhou haixia and the Hainan Island present's shape. the geologic structure movement causes Hainan anticlinal bowing is middle Hainan Island jacks unceasingly, has formed the present Hainan Island's landform characteristic gradually; The mountainous region is located at the central committee, the hill, the terrace, the plain surrounds in turn all around. Hainan Island average elevation 20 meters. 500 meters above mountainous regions occupy entire island's 25%,100 meters above plains, the terrace to occupy 2/3.
