I THINK 0.01...i think meaning im not 100% sure but i hope this helps
Answer:T
he answer is C
Let's go through the options:
a. declare sovereignty in a document, such as the Declaration of Independence
-this is a good start, but it's not enough, a number of states have declared sovereignty but they were not recognized internationally.
b. pass a law requiring other states to recognize its sovereignty
- a state can't pass a law about what the others should do: this is a false answer
c. gain recognition of sovereignty from the United Nations
-this is the best way of achieving sovereignty in a way that is recognized internationally - this is the best answer.
d. merge with another state and form a new state
-this is not the right answer - this state would not be sovereign then.
Explanation:
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.
Answer:
They are youngest close to the ridges,
Explanation:
At the ocean ridges, there is divergence at their margins.
Therefore, new materials upwell from the mantle below to the surface.
- The basaltic materials cools and solidifies at the margin.
- This action forces the old lithosphere backwards as the plate pulls away.
- At the margin of the ridge, the rocks are younger.
- Away from the margin, the crust begins to grow older.
So, at the margin the age of the rocks are more younger than those away from the margin.
Geothermal activity visible on the surface,acute to extreme seismographic readings. typically on the borders of tectonics plates. (Ring of fire)
