Question

1. Why are the levels of all
world?
2. How is the sea level measured?
What are the uses of maps showing height?​

Answer 1

Answer:

1.A- Because the ocean is one continuous body of water, its surface tends to seek the same level throughout the world. However, winds, currents, river discharges, and variations in gravity and temperature prevent the sea surface from being truly level.

2.A- Sea level is primarily measured using tide stations and satellite laser altimeters. Tide stations around the globe tell us what is happening at a local level—the height of the water as measured along the coast relative to a specific point on land.

Maps showing height can prove to be very useful in various ways: It shows the surface elevation. It shows the display in 3 D computer graphic. They are widely used to understand the nature of terrain.

Hope it helps :)
