7 0

Explanation: Since air has mass, it also has weight. The pressure of air at a given place is defined as a force exerted in all directions by virtue of the weight of all the air above it.

The weight of a column of air contained in a unit area from the mean sea level to the top of the atmosphere is called the atmospheric pressure. The atmospheric pressure is expressed in various units.

Measurement of Air Pressure

Atmospheric pressure is the weight of the column of air at any given place and time. It is measured by means of an instrument called barometer.

The units used by meteorologists for this purpose are called millibars (mb).

One millibar is equal to the force of one gram on a square centimeter. A pressure of 1000 millibars is equal to the weight of 1.053 kilograms per square centimeter.

In other words, it will be equal to the weight of a column of mercury 75 cm high.

The normal pressure at sea level is taken to be about 76 centimeters (1013.25 millibars).

Vertical Variation of Pressure

In the lower atmosphere the pressure decreases rapidly with height.

If the Juan de Fuca Plate continues to move away from the Pacific Plate at the same speed as shown on the graph, how many meters

diamong [38]

The distance that Juan de Fuca Plate would move is 290 meters.

<u>Note:</u> The Juan de Fuca Plate is moving southeast away from the Pacific Plate at a speed of 29 mm/year.

<u>Given the following data:</u>

Speed = 29 mm/year.

Time = 10,000 years.

To determine the distance that Juan de Fuca Plate would move in meters:

First of all, we would convert the value in millimeters (mm) to meters (m) as follows;

<u>Conversion:</u>

1 millimeter = 0.001 meter

29 millimeter = X meter

Cross-multiplying, we have:

$X = 0.001 \times 29$

X = 0.029 meter.

Speed = 0.029 meter/year.

Mathematically, the distance covered by an object is given by this formula:

$Distance = speed \times time$

Substituting the given parameters into the formula, we have;

$Distance = 0.029 \times 10000$

Distance = 290 meters.
