What happens when magma convection currents move in opposite directions?
Semenov [28]

<u>Answer:</u>

During the "magma convection currents", the plate tectonics are pulled apart from each other. This is because if the "magma convection currents" flow in opposite direction, the plates present floating on the molten magma also float apart, causing divergent plate boundaries.

The plate tectonics are responsible for the movement of continental plates. The molten magma present inside the earth acts as a vast ocean on which the plates move as sheets. So if currents flow away from each other they take the plates along with them too, forming great rift valleys.

<span>mitosis occurs more in your body since it changes, modifies and requires cell division at maximum rate in many useful situations with the stand to a particular system and organ. Mitosis and meiosis are simply cell division processes that occurs differently, they're characteristically divergent from each other according to their function and structure. Mitosis is the cell division that happens in all cells in the human body except sperm and egg cells. They produce diploid cells. Meiosis on the other hand is responsible for the cell division of the gametes, spermatogenesis (sperm cells) and oogenesis (egg cells), such haploid cells. Take for instance your integumentary system, layer of the skin in which your stratum basale always produces new epithelial cells (via mitosis) to take over until the outer layer, called stratum corneum (a continous replaced dead cells in this layer). </span>
