A measure of the amount of light given off by a star is its absolute luminosity or magnitude. Absolute magnitude<span> is the measure of </span>intrinsic brightness<span> of a celestial object. It is the hypothetical </span>apparent magnitude<span> of an object at a standard </span>distance<span> of exactly 10 </span>parsecs<span> (32.6 </span>light years<span>) from the </span>observer<span>, assuming no </span>astronomical extinction<span> of starlight. </span>
Explanation:
This is not pole reversal. Pole reversal does not control how a rocks are formed, they only align the orientation of magnetic minerals in a cooling rock.
Pole reversals occur when the direction of the magnetic north and south changes.
- The rock type with the quartz band oriented perpendicularly from one another must have been formed along a fracture in the rock formation.
- Fractures structurally controls how intrusions are formed.
- The quartz band must have been a fluid from a magmatic body that crystallizes at the late stage with some other minerals.
- Fractures acts as weakness planes in rocks and they are utilized by intrusive bodies to cool.

Answer: The ice has been melting and declining
Explanation:
Due to an increase in industrialization, global warming is occurring. This has increased the average temperature around the globe considerably.
As you probably know, ice needs to be in a cold environment to stay frozen. <em>Arctic sea ice</em>, which is ice that floats in the sea near the Arctic, <em>has been </em><em>melting</em> due to global warming.
In addition, the land ice on Antarctica and Greenland has <em>also been </em><em>melting</em> due to global warming. The increase in average temperatures around the globe has created an environment that is <em>too warm</em> for ice.
In conclusion, <em>global warming</em> has caused Arctic sea ice, and land ice on Antarctica and Greenland, to <em>melt</em>. The globe <em>is warmer than it once was</em>. This means that the water that once was frozen is now melting. If we don't stop heating the planet, <em>sea levels will rise </em>due to the melting ice, and catastrophe will occur. Tens of thousands of animals will die, homes will be lost, and storms will increase in intensity and frequency if we don't reverse the effects of global warming <u><em>now.</em></u>
Save the Arctic, please.
