Earth's Reference Points

The video tutorial explains how to determine a location on Earth using imaginary lines of latitude and longitude. It describes the equator as 0 degrees latitude, dividing the northern and southern hemispheres, and provides examples of locations with specific latitudes. The concept of meridians or lines of longitude is introduced, with the Prime Meridian at 0 degrees longitude, and how locations are measured in degrees east or west of it.

• There are no visible landmarks in some areas.

• Imaginary lines are difficult to understand.

• The Earth is too large to measure.

• There are no tools available for measurement.

Which line divides the Earth into the northern and southern hemispheres?

• The Tropic of Cancer

• The Equator

• The Arctic Circle

• Minneapolis, Minnesota

• Nairobi, Kenya

• Greenwich, England

• Sydney, Australia

What is the significance of the Prime Meridian?

• It is the same as the equator.
