This table shows sizes of Earth's oceans. Based on this table and the makeup of Earth's total water, which reasonable conclusion can be made? A) Earth's seas contain more salt water than the oceans. Earth's land has more surface area than Earth's oceans. Earth's largest source of salt water is the Pacific Ocean. D) The Pacific Ocean is larger than all other oceans combined. USATestprep, LLC...

The answer would be

C) Earths largest source of salt water is the pacific ocean

It would be Earth's largest source of salt water is the Pacific Ocean.

Explanation:

D is false because if you add all the percentages of the other oceans up. it would be greater than the pacific ocean, so its wrong.

a mercury barometer is a device that uses the physical properties of mercury in a tube to measure barometric pressure. mercury barometers are used for : -

1. measurement of atmospheric pressure  

2. determining the altitude of a place

3. weather forecasting

4. calibration and checking of aneroid barometers

5. application in fluid mechanics

6. measurement of pressure in aircrafts

7. surface weather analysis

8. preparation of barographs

9. usage in physical sciences like physics, astronomy & chemistry

10. preparation of aircraft altimeters

characteristics of mercury barometer : -

1.used to define and measure atmospheric pressure.

2.on the average at sea level the column of mercury rises to a height of about 760 mm.

3.this quantity is equal to 1 atmosphere.

4.it is also known as standard atmospheric pressure.

5.a barometer in which the weight of a column of mercury in a glass tube with a sealed top is balanced against that of the atmosphere pressing on an exposed cistern of mercury at the base of the mercury column, the height of the column varying with atmospheric pressure.

have a great day because if you dont you and i will be sad
