Sponsored by: By choosing to build from a pre-drawn plan â as opposed to hiring a residential architect to create a custom home â you've already taken a big step toward building a great home at the right price. But not all pre-drawn plans cost the same to build. You can still keep costs down and have a beautiful home by keeping several principles in mind.

Water covers 71% of the Earth's surface; the oceans contain 96.5% of the Earth's water. The Antarctic ice sheet, which contains 61% of all fresh water on Earth, is visible at the bottom. Condensed atmospheric water can be seen as clouds, contributing to the Earth's albedo.
Even though the planet is 71 percent water, the largest percentage of Earth's water is saltwater in the oceans and cannot be used for drinking. The table describes the main locations of water on Earth. Notice that about 98 percent of Earth's water is saltwater. The remaining 2 percent is freshwater, but the majority of that percentage is found in the polar ice caps and glaciers, which is not readily available to us.
