I am pretty sure the answer is <span>d. all of the above.
Hope this helps</span>
The main reason why the tectonic plates move is the conversational currents. There is magma between the upper mantle and the asthenosphere that heats up at the upper mantle. The weight is so small that the magma rises with the help of these conversational currents. When the magma has ascended towards the asthenosphere, it has nowhere to go so the magma lies along the asthenosphere. There the magma cools down again because the asthenosphere is colder than the upper mantle, which makes the magma heavier and goes back down to the upper mantle, where the magma heats up again and everything starts all over again and so it goes on over and over again. Scientists have concluded that the earth's gravity causes two other processes that also cause the tectonic plates to move.
Ridge push - in the spreading zones, the sides of the tiles are raised and slide to the side as in a slide.
Slab pull - when a plate is pulled down by gravity in a subduction zone like an anchor.

That is the point in Mars' orbit when it comes closest to Earth, this time at about 38.6 million miles (62.07 million kilometers) from our planet. Mars was visible for much of the night in the southern sky and at its highest point at about midnight.

Answer:
D) it turns steam when released
Explanation:
In a nuclear reactor, the superheated water leaving turns to steam when released and it in turn is channeled to turn turbines in order to produce electricity.
- A nuclear reaction is used to generate current through a series of processes.
- The reaction produces a significant amount of heat energy.
- This heat energy is used to superheat water and convert it to steam.
- The steam is then channeled to drive turbines whose mechanical rotation produces electricity.
