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.
Answer:
c=49 degrees
b=131 degrees
Explanation:
Angle c and the angle that measures 49 degrees are opposite angles. Opposite angles are equal to each other, so we can conclude that angle c is equal to 49 degrees.
c=49 degrees
Angle c and angle b are both sitting on a straight line, and a straight line has an angle measure of 180 degrees. To find angle b, we can subtract 49 from 180.
b=180-49
b=131 degrees
Therefore,
c=49 degrees
b=131 degrees
I hope this helps!
Hi there!
You will have already be known that the <em>sun's rays are closest to the equatorial regions</em> <em>than</em> the <em>polar regions</em>. So the stronger heat rays reach the equator first, heating it's water faster. Within the span of time when the rays reach the polar areas (poles), the sun rays become slanted, leading it into the ocean waters.
Also, the sharpness or intensity of the rays gets weakened, thereby heating the water of polar regions less.
Using this fact, we can say that the rays falling near the equator heats the water more than the rays heating the water at poles.
Hence, we can say that <u>D) </u><u>T</u><u>he sun heats earth and it ocean unevenly</u> will be your answer.
Thank you !
