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 Installation labor to replace an above ground pool liner can cost $200-$800 or more, depending on local rates and the size and shape of the pool. 2  For example, Edwards Pools in Ohio estimates its labor charges for replacing an above ground pool liner vary from $400 for an 18' round pool to $700 for a 18'x33' oval. Replacing a vinyl liner in an in-ground swimming pool typically costs $700-$1,500 for just the liner, depending on the size and shape of the pool, the thickness (20-30 mil, but typically 28 mil) of the liner and any special colors or designs on the liner.
