Answer:
D) in volcanic eruptions, plate movements thrust hot magma up into Earth's crust, where it cools and hardens.
Explanation:
Plate tectonics influences the formation of metamorphic rocks because it is produced in the process of subduction. In subduction process, volcanic eruptions, plate movements push hot magma up into Earth's crust, where it cools and hardens due to low temperature. Due to this process of subduction, plate tectonic movements causes the formation of metamorphic rocks in the earth.
Answer:
The difference between the independent and dependent variable is that the independent variable is the cause, while the dependent variable is the effect.
Explanation:
Imagine a cause and effect scenario. For example, Chris went gambling for 6 hours, and he lost $1,000. The time spent gambling (6 hours) is the independent variable, while the money lost gambling ($1,000) is the dependent variable because you can't lose the money if you never went gambling. The independent variable is the variable that is changed, i.e fertilizer 'x' in an experiment, the dependent variable is the variable affected by this change in the independent variable, i.e fertilizer 'x' affected a plant to grow 'y' amount.
