Maps of Latitude and Longitude
Earth is the third planet from the Sun and the only astronomical object known to harbor life. Our home planet Earth is a rocky, terrestrial planet. It has a solid and active surface with mountains, valleys, canyons, plains and so much more. Earth is special because it is an ocean planet. Water covers 70% of Earth’s surface.
The Earth rotates around its axis. The axis is an imaginary line passing through the center of the Earth. Its two ends of the surface its called North and South Poles. Earth completes a rotation in 24 hours, exact 23 hours, 56 minutes, 4 seconds.
Latitude is a geographic coordinate that specifies the north-south position of a point on the Earth’s surface. It is a measurement on a globe or map of location north or south from 0° at the Equator to 90°. The distance of a degree of latitude is about 111 km (60 nautical miles), at the Equator to 111.699 km at the poles. Geographic latitude is also given in degrees, minutes, and seconds.
Longitude is a geographic coordinate that specifies the east-west position of a point on the Earth’s surface. It is a measurement on a globe of location 180° both east or west from 0° at the prime meridian at Greenwich. The distance of a degree of longitude at the Equator is about 111.32 km (69.18 nautical miles) and at the poles, 0. Geographic latitude is also given in degrees, minutes, and seconds.
