The earliest of civilizations were based around river valleys. This allowed them to irrigate fresh water to their crops allowing for better farming and therefore, bigger and better civilizations.
<u>Answer:</u>
<em>The two primary factors that impact how a well of lava will eject are consistency and gas content. </em>
<u>Explanation:</u>
<em>Both are identified with the arrangement of the magma. </em>Hawaiian volcanoes will in general emit basalt , which is low in consistency and low in gas content (about 0.5 weight percent).
The higher the level of silica substance of magma, the more thick it is. <em>Since a magma with less silica substance is moderately liquid and has a high capacity to stream (low consistency)</em>

Answer:
It is partially true, "life finds a way" but human activities have already made some irreversible damage to the world.
Explanation:
In a Hypotethic scenario in which Humans are extinct nature Will eventually, start succession processes in urban areas and after many years depending on the erosional resistance of the materials nature will erase many of the buildings around the world ( 500 years for metal). Water bodies will eventually decontaminate trough the water cycle and be filled with organisms, contamination due to petrol can also be reverted through natural chemical processes with oxygen.
But human activities like mining are irreversible, for the earth, it is impossible to recover its shape, the materials already extracted and soil nutrients that ran out due to the use of chemicals.
The acceleration of the climate change due to human activities is for sure the biggest wound we have made to the world, this is an irreversible acceleration to a natural process.
