If all silicate mineras melted at exactly the same temperature, would magmas of different compositions even exist? How is partia

omeli [17]

Answer:1. Yes, there are magma of different composition in existence. silicate mineral become molten at the same temperature of 1200 degree centigrade in igneous rock formation and this does not stop the composition of magma which are of three types basalic, andesitic and rhyolitic each of them have different composition ranging between iron, magnesium and calcium.

2. Partial melting is the reason why we have different forms of rock, this is because the mantle is composed of different minerals, these minerals doesn't melt uniformly, a mineral with low melting point will turn to liquid while the one with high melting point will turn to solid crystals. As the magma melts and flow slowly before it cools into solid rock it undergoes some physical and chemical changes which causes differences in the rock formed.

3. The last question depends on ever individual's location, where i am i can easily go and see granite at a mining site that deals with construction rocks which is an example of igneous rock.

You are at 35 N and 175 W; you move to a new location which is 40 south and 60 west of your present position. What are the coord

evablogger [386]

Answer:

The new coordinates are 5S and 125E

Explanation:

Addition of latitudes:

If they are in the same direction, you just have to add the values.

For example, 5N + 10N = 15N.

You have to be careful that we don't have any latitude higher than 90. So, if the result of your sum is higher than 90, we subtract 180 by the result, and the position is in the other hemisphere.

For example

60N + 40N = 100N

100N is larger than 90, so not possible

Subtracting and changing hemisphere

180 - 100N = 80S

When they are in opposite directions, you can just say that one hemisphere is the positive one, and the other is the negative.

In this problem, i am going to say that the North hemisphere is the positive one and the South the negative.

So, currently at 35N moving 40S. The new position is

$P = 35 - 40 = -5$

Since the result is negative, this just means that we are in the Southern Hemisphere, so 5S

Adittion of Longitudes:

They work just like the latitudes, the difference is that we don't have any longitude higher than 180. So, if we have a result higher than 180, we subtract 360 by this value and change the hemisphere.

In this problem.

175W + 60W = 235, higher than 180, so:

360 - 235 = 125E
