Equator represents

b) line joining North and South poles

c) axis of rotation of Earth

An equator is the intersection of a sphere’s surface with the plane perpendicular to the sphere’s axis of rotation and containing the sphere’s center of mass. Notably, the Equator refers to the Earth’s equator, per above: an imaginary line on the Earth’s surface equidistant from the North Pole and the South Pole, dividing the Earth into the Northern Hemisphere and Southern Hemisphere.

Other planets and spherical astronomical bodies have equators similarly defined. The length of the Equator is roughly 40,075 kilometers.

Answer: (b)

Earthquakes are caused by faulting, a sudden lateral or vertical movement of rock along a rupture (break) surface. Earthquakes often occur in volcanic regions and are caused there, both by tectonic faults and the movement of magma in volcanoes.

Such earthquakes can serve as an early warning of volcanic eruptions, as during the Mount St. Helens eruption of 1980.
