ROCKS AND MINERALS

Geography
1 answer:
vodomira [7]3 years ago
7 0

Geologists have recently determined that the minerals goethite and hematite exist in abundance on Mars, sure signs of the presence of water (see Figure 1 for a picture). None of those geologists have been to Mars, of course, but the unmanned rovers Spirit and Opportunity have. These rovers are equipped with three mass spectrometers, each of which is capable of determining the chemical composition of a solid with a high degree of accuracy. With such a precise chemical analysis in hand, geologists on Earth had no problem identifying the minerals.

A mineral is defined in part by a specific chemical composition. In theory, therefore, it is always easy to identify a mineral, if you can determine the chemical composition with a mass spectrometer like the Mars rovers. In reality, however, even if you are looking at rocks on Earth, determining the exact chemical composition of a substance involves significant time preparing the sample and sophisticated laboratory equipment (and often significant money). Luckily, it is usually unnecessary to go to such lengths, because there are much easier ways that require little more than a magnifying lens and a penknife.

THAT QUESTION - If an area of HIGH pressure were located to the EAST of West Chester, what would be our surface wind direction?
sergij07 [2.7K]

If an area of HIGH pressure were located to the EAST of West Chester, our surface wind direction would be - south.

<u>Explanation:</u>

A system of high pressure contains pressure to be very higher at the center of the area than the other areas around it. The blowing of wind wind takes off the high pressure built in an area. An anticyclonic flow occurs when the system high pressure winds blows in a direction that is opposite to the system of low pressure winds.

It blows in the clockwise direction in the  northern side of the equator and anticlockwise in southern side of equator. The direction of surface wind will be opposite in the low pressure systems. Thus, if a high pressure exist in an area then the direction of surface wind will be opposite direction.
