Answer:
1. 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. 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.
3. It shows the surface elevation. It shows the display in 3 D computer graphic. They are widely used to understand the nature of terrain. Gives the actual displacement and location of mountains and valleys
4. As altitude rises, air pressure drops. In other words, if the indicated altitude is high, the air pressure is low. ... This is what meteorologists and mountaineers mean by "thin air." Thin air exerts less pressure than air at a lower altitude. High-altitude locations are usually much colder than areas closer to sea level
5. Maps use symbols like lines and different colours to show features such as rivers, roads, cities or mountains. ... All these symbols help us to visualise what things on the ground actually look like. Maps also help us to know distances so that we know how far away one thing is from another.
