About 200 million years ago, the supercontinent began to break up. Gondwana (what is now Africa, South America, Antarctica, India and Australia) first split from Laurasia (Eurasia and North America). Then about 150 million years ago, Gondwana broke up.
The installation costs of above ground pools usually run $1000-$3000, depending on the size and type of pool. Keep in mind that oval pools normally cost more to install than round pools, and the kits are also more expensive. $800 run a power line for the motor - $400 for above ground pool fence and alarm (town requirement) - $300 for landscaping after installed the pool (seeding and stone around the pool, etc) - then ofcourse monthly cost to maintain the pool and opening and closing cost. hope this helps.
For the purpose of this discussion, we will look at the costs associated with the installation of both kinds of modern swimming pools. According to P.K. Data the average cost of a 19' diameter above ground swimming pool is $6,243; while the average cost of a 32'x16' inground swimming pool is $21,919. The vinyl is the least expensive with a standard cost of roughly $18,000. 2  The fiberglass bump up the costs to $20,000 without installation. 3  There are also concrete and gunite pools that require around $20,000 to $50,000 to install.
