Answer:ince x=14 is a vertical line, there is no y-intercept and the slope is undefined.
Explanation:
<span>The equator is 0 degree latitude. This imaginary line, which runs through parts of South America, Africa, and Asia, is officially the halfway point between the North Pole and the South Pole.</span>
<span>The prime meridian is 0 degrees longitude. This imaginary line runs through the United Kingdom, France, Spain, western Africa, and Antarctica.</span>
By using the equator and prime meridian, we can divide the world into four hemispheres, north, south, east, and west. For instance, the United States is in the Western Hemisphere (because it is west of the prime meridian) and also in the Northern Hemisphere (because it is north of the equator).
<span>These lines are merely for the identification of where things are on a map or a globe.</span>
Answer:
<u>Called as mantel melting</u>
Explanation:
- The mantel rocks can break and melt without the increase in temperature due to the overexerted pressure of the rocks.
- This process is called decompression melting. Rocks can melt in the mantel due to dehydration thus producing molten magma and lava.
- As the rocks don't melt homogeneously there is a complex mixture of mineral content during the subduction and presence of volatile substances like the water or CO2.
