Answer 1

1. Ans.

This is 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. Ans.

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.

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.

Difference between the lifestyle of people living on high altitudes and low altitudes :-

• Most of the people that live at high altitudes have very low risk of becoming overweight or obese whereas the people living at low altitudes have very much risk of becoming overweight and obese. At the low altitudes, the level of oxygen is normal but the high altitudes have low levels of oxygen, that suppress hunger by secreting leptin - a hormone that makes people feel full. That's why the people living at the high altitudes are not obese.

• The people living at high altitudes may have altitude sickness. The symptoms include fatigue, nausea, headache, vomiting, dizziness, insomnia, water retention, high blood pressure etc while people living at low altitudes do not have altitude sickness instead they have health problems like hypertension, diabetes, thyroid and other diseases just because of their hectic schedule and luxurious life style.  
• Most of the people that live at high altitudes are healthy and fit because they have to walk on the hilly region. Very few of them may be slightly overweight or obese. While many people that live at low altitudes are not healthy and fit just because they use vehicles to move from one place to another. They do not want to walk on their feet even for short distances.
