Igneous rock derives it's name from the Latin word ignis which means fire. It is formed when the magma after volcanic eruption gets cool and solidified either on the surface of earth crust or inside the earth crust. These rocks are characterized by their hardness. These rocks undergoes no chemical weathering but exhibit very low mechanical or physical weathering may occur. Therefore, hardness is the property which can be used to identify the origin of an igneous rock.
Answer:
2000m
Explanation:
Given parameters:
Rate of regional erosion = 2 m per 1000years
Unknown:
Amount of regional erosion in 1, 000, 000 years.
Solution:
If it takes 1000 years for regional erosion to remove 2m of earth
then, in 1, 000, 000 years, the amount of regional erosion will be: 
⇒ 2000m
In a million years to come, 2000m of earth would have been eroded as a result of regional erosion.

The Turkic people were trying to force the Islam on the Armenians, while the Armenians wanted to keep their faith at any cost, so they had lot of conflicts over the past few centuries.
Another reason fro the ill will between the Armenians and the Azeris has been the region of Nagorno Qarabag, which actually even led to a war between the two.
