The Cold War occurred around just 30 years after the communist revolution in Russia.
Hope I helped!
I believe that is a trick question, “The degree of metamorphism is a function of pressure, heat and time. During orogenic events, the metamorphism of the rocks can take 100's of thousand to millions of years. Too much heat cannot be applied at once since the rock will melt and recrystallize into an igneous rock” i’ve found those same answers on other websites as well. meaning there really isn’t a right answer.
Answer: Summary. Intrusive igneous rocks cool from magma slowly because they are buried beneath the surface, so they have large crystals. Extrusive igneous rocks cool from lava rapidly because they form at the surface, so they have small crystals. Texture reflects how an igneous rock formed.
Hope this helps....... Stay safe and have a Merry Christmas!!!!!!!!! :D
Explanation:
The <em>Mid-Atlantic Ridge </em>is composed of the youngest crustal bedrock.
Answer:
Caverns are created when moving groundwater mechanically weathers sediment and transports it elsewhere, leaving behind large empty spaces.
Explanation:
The movement of groundwater causes erosion that is responsible for the formation of caves. These caves are formed due to mechanical weathering of rocks. Mechanical weathering plays an major role in creating caverns by dissolving of limestone rock due to acidic water that reacts with limestone and removes it with the passage of time that forms caves. The normal pH water can't perform this job due to no reaction occurs with limestone.
