4. The image shows water waves approaching the boundary between an area of slower speed and an area of higher speed. The boundary is marked by a dashed line.
The original direction of the wave is shown by the arrow on the left. What will happen to the wavelength and direction of the wave as it crosses the boundary?

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.

c) a core temperature of only ten thousand kelvin
