People who live at high altitudes must adjust to lower atmospheric pressure.
Altitude describes a location's elevation above or below sea level. As your altitude increases, the atmospheric pressure decreases, causing changes in the environment and in your daily routine. For example, water boils at a lower temperature at high elevations, increasing cooking time for boiled pastas, steamed vegetables and soups. Vehicles require engine adjustments and reduced tire pressure. Even your body has to adjust to thinner air and faster dehydration rates. Because of these differences, it is helpful to know the altitude of a particular address.

5. Click on the circle that corresponds to your address. The elevation in feet and meters appears on the map.
Google Earth
6. Download Google Earth at google.com/earth/download/ge/agree.html.
7. Launch the program and expand the "Search" tab by clicking on the down arrow.
8. Enter your address into the "Fly To" box. Google Earth navigates to your location and puts a box with a crosshair over your address.
9. Place your mouse cursor over the box until it lights up. The information bar at the bottom of the map shows your elevation.
