As the human population continues to increase exponentially, what is one important way that humans can
help to minimize their impact on global warming?
O Use mass transit, such as buses and trains, and carpool more often.
O Consume produce from large farms and agribusinesses instead of food
grown locally.
O Operate appliances during peak hours of the day instead of in the evening
and night.
Build houses in the suburbs instead of homes in major cities and urban
centers.

120,630,890

step-by-step explanation:

110+10=120,620+10=630,880+10=890

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.
