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.
1 Installing an aboveground pool can cost $1,500-$5,000; for in-ground estimated costs are $7,000-$16,000 for a vinyl-lined model, $15,000-$25,000 for a fiberglass shell and $17,000-$45,000 for concrete or gunite. 2  However, custom designs can run prices much higher.
