Answer:
There are 360 degrees of longitude (+180° eastward and −180° westward.). The longitude line of 0 degrees is known as the Prime Meridian and it divides the world into the Eastern Hemisphere and the Western Hemisphere.
Longitude (meridians) are the vertical lines on a map. They all converge at the two poles (North Pole and South Pole), and 0° longitude is located at Greenwich, England (0°). In the east hemisphere, the longitude ranges from 0° to 180°E, and in the west hemisphere,the longitude ranges from 0° to 180°W.
Explanation:
Answer: seafloor spreading and subduction magmatism
Explanation: Continental crust are termed as the crust destroyed by plate tectonic process mostly.Continental crust usually lies above sea level and because of this existence of land life to evolve from marine life possible.
Seafloor spreading is a type of process in which tectonic plate of Earth's lithosphere separate from one another. Subduction is also a process related with continental crust that occurs when tectonic plates collide with each other rather than getting apart.
Answer:
Arithmetic Density
Explanation:
it is the total number of people divided by the total land area and this is just talking about population density not the amount of arable land (physiological density) or comparing the number of farmers to the area of arable land (agricultural density)
