Geography

Sholpan [36]3 years ago
6 0
Formed-
Volcanoes are formed when magma from within the Earth's upper mantle works its way to the surface. At the surface, it erupts to form lava flows and ash deposits. Over time as the volcano continues to erupt, it will get bigger and bigger.

Erupts-
When it's underneath the surface, the molten rock is called magma. When it reaches the surface, it erupts as lava, ash and volcanic rocks. With each eruption, rocks, lava and ash build up around the volcanic vent where the material blasts out of.

Which statement best describes 0 latitude?
Wittaler [7]

Answer:

C. An imaginary line that splits Earth in half between the North Pole and the South Pole

Explanation:

The 0-degree latitude line is the equator. It is the only line of latitude that is a great circle. The equator divides the earth equally between the North Pole and the South pole.

Places above the equator are the northern hemisphere whereas, those below fall into the southern hemisphere.

  • The equator is the only known great circle.
  • All other lines of latitudes are small circles.
  • Most places along the equator usually have the sun overhead and receive direct insolation.

Other choices are wrong;

  • The northernmost point on earth is the north pole
  • An imaginary line that runs through Greenwich in London is the Prime meridian
  • The southernmost point of Earth is the south pole.
