One effect that plentiful harvests had on ancient civilizations of the mainland's river valleys was to help have larger populations and the need to have materials to survive.
The statement is True. Large volcanic eruptions have the potential to lower global temperatures but typically for only 1-3 years.
A volcanic eruption is when lava and gas are released from a volcano—now and again explosively. The maximum risky type of eruption is called a 'glowing avalanche' which is when freshly erupted magma flows down the edges of a volcano.
The melted rock, or magma, is lighter than the encircling rock and rises up. This magma collects in magma chambers, but it's far still miles underneath the surface. While sufficient magma builds up inside the magma chamber, it forces its manner up to the floor and erupts, often causing volcanic eruptions.
Sixty percent of all energetic volcanoes arise on the obstacles between tectonic plates. maximum volcanoes are observed alongside a belt, called the “Ring of fire” that encircles the Pacific Ocean. A few volcanoes, like those that form the Hawaiian Islands, occur within the indoors of plates at areas referred to as “hot spots.”
