HELP ASAP 1. Why do land breezes occur at night?

a Land cools off slower than water, so the air above water is cooler.

b Water cools off faster than land, so the air above land is warmer.

c Land heats up slower than water, so the air stays cooler during the day.

d Water cools off slower than land, so the air above water is warmer.\

2. Air above a hot surface heats up.
a True

b False

3. Which statement correctly defines wind?

a Wind is the movement of air to a colder area in the atmosphere.

b Wind is the movement of air pushed around and bouncing off Earth's surface.

c Wind is the movement of air from areas of high pressure to areas of low pressure.

d Wind is the movement of air from areas of low pressure to areas of high pressure.

here are the answers !

Explanation:

1) the land surface cools quicker than the water surface at night. So the best Answer would be D

2) I think this answer would be True because When a fluid such as air or water touches a hot object, it can heat up and then move in bulk as a fluid, thereby carrying the heat quickly to new locations. Hot air rising is a common example of heat convection.

3) Wind is the movement of air from areas of high pressure to areas of low pressure.

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.
