Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.
Answer:

The dependent variable is the result in the experiment. It depends on the independent variable to occur. Hence, the word dependent :) In this situation, the light is the independent variable because it is the factor that the experimenter is changing. It is the only thing that the experimenter changes in the experiment. The resulting plant growth is the dependent variable because it depends on the amount of light to grow. Hope that makes sense!
