The lowest elevation limiting stream erosion is called the base level. It refers to the point at which a stream can no longer erode its bed any lower. This can be either sea level for rivers that flow into the ocean or a lake level for rivers that flow into a lake.
Louisiana's average elevation is 98 feet above sea level. The mean elevation of Wyoming is 6,700 feet above sea level.
Jacksonville has a lower elevation. Jacksonville is 16 feet (5 meters) above sea level while Orlando is 82 feet (25 meters) above sea level.

Kabul, the capital of Afghanistan, is situated at an elevation of approximately 1,800 meters (5,900 feet) above sea level, while Dhaka, the capital of Bangladesh, is much lower, at about 9 meters (30 feet) above sea level. Therefore, Dhaka is likely at a lower elevation compared to Kabul.

Florida has lower elevation than Tennessee. Florida's lowest point of elevation is sea level at the Atlantic Ocean and at the Gulf of Mexico. Tennessee does not have any point of elevation at sea level.
40 feet below sea level is at a higher elevation than 14 feet below sea level. Elevation is measured by the distance above or below a reference point, such as sea level, so the higher the number below sea level, the lower the elevation.
Gravity is what causes a river to flow from higher to lower elevation. A river travels at a faster speed the higher the elevation and will typically cause greater erosion.
Cairo has a lower elevation than Nairobi, with Cairo being approximately 23 meters above sea level and Nairobi being around 1,795 meters above sea level.
A region that lies below the level of the surrounding land is called a depression or basin. This area typically collects water and can be characterized by lower elevation compared to its surroundings.
