Iwill give brainlieset need asap which phrase accurately describes erosion? a. breaking rocks into smaller pieces and reforming them into new rock b. forming rocks and depositing them in new places c. moving bits of rock and soil across the earth’s surface by water, wind, or glaciers d. forcing rocky plates against each other and creating mountains

-

C moving bits of rock and soil across the earth’s surface by water, wind, or glaciers.

Explanation:-

When various surface phenomenon move materials present on the earth's surface from one location to another it is known as erosion.The materials are usually rocks, soil and dissolved materials.

The most common surface phenomenon are wind, water and glaciers. Erosion differs from weathering in that there must be movement of the materials.

The rates of erosion depends on various geological factors like rainfall, wind speed, rivers and even time.

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.
