The Rock Cycle. Arrows point from 1 stage to next. 1. Metamorphic Rock to point K to Magma to point V to Igneous Rock to Melting back to magma. 2. Metamorphic Rock to point K to Magma to point V to Igneous Rock to Heat and Pressure. 3. Metamorphic Rock to point K to Magma to point V to Igneous Rock to Weathering and Erosion to Sediment to Compacting and Cementing to Sedimentary Rock to Heat and Pressure to Metamorphic Rock. 4. From Sediment to Compacting and Cementing to Sedimentary Rock to Weathering and Erosion back to Sediment. 5. Metamorphic Rock to Weathering and Erosion to Sediment. Which event most likely occurs at point V?

cooling
erosion
heating
melting

Cooling

Explanation:

Metamorphic Rock to point K to Magma to point V to Igneous Rock to Heat and Pressure.

Point V would be cooling,

In the rock cycle, one rock can turn into another rock. A metamorphic rock can turn into an igneous rock through 2 process, namely melting and cooling. If a metamorphic will undergo tremendous heat, it could melt into magma. If magma cools down it would turn into an igneous rock.

In summary:

Metamorphic rock→ melting (Point K)→magma→cooling (Point V)→Igneous Rock

d. stage 4

explanation:

the existence of some kind of demographic transition is widely accepted in the social sciences because of the well-established historical correlation linking dropping fertility to social and economic development.[1] scholars debate whether industrialization and higher incomes lead to lower population, or whether lower populations lead to industrialization and higher incomes. scholars also debate to what extent various proposed and sometimes inter-related factors such as higher per capita income,lower mortality, old-age security, and rise of demand for human capital are involved.[2]
