Navigating Earth's Coordinate System: Latitude and Longitude Explained

The video tutorial explains the concepts of latitude and longitude, which are imaginary lines used to locate places on Earth. Latitude lines run horizontally and are measured in degrees north or south of the equator, while longitude lines run vertically and are measured in degrees east or west of the prime meridian. The tutorial also covers important lines such as the equator, tropics, and poles, and explains how to use maps and reference tables to understand these coordinates. Additionally, it discusses the breakdown of degrees into minutes and seconds for precise location measurement.

What is the equator's role in the coordinate system?

• It is the largest circle of longitude.

• It divides the Earth into eastern and western hemispheres.

• It is the zero mark of longitude.

• It divides the Earth into northern and southern hemispheres.

Which of the following is true about lines of latitude?

• They are measured in degrees east and west.

• They intersect at the poles.

• They are parallel and never intersect.

• They run from top to bottom.

What is the prime meridian?

• The line dividing the Earth into eastern and western hemispheres.

• The zero mark of longitude.

• The zero mark of latitude.

• The line dividing the Earth into northern and southern hemispheres.

Which line is on the opposite side of the Earth from the prime meridian?

• The Tropic of Cancer

• The international date line

• The equator

• The Arctic Circle

What is unique about the surface ocean current maps discussed?

• They only show the northern hemisphere.

• They show the prime meridian as a straight line.

• They reverse the typical east-west orientation.

• They do not include the international date line.

How are degrees of latitude and longitude further divided?

• Into east and west

• Into kilometers and meters

• Into minutes and seconds

• Into hours and minutes

What is the significance of 41 degrees and 30 minutes north?

• It is the equator.

• It is halfway between 41 and 42 degrees north.

• It is the prime meridian.

• It is the international date line.

How do the numbers change as you move west on a longitude map?

• They decrease as you approach the international date line.

• They increase as you approach the international date line.

• They remain constant.

• They decrease as you move away from the prime meridian.

What is the relationship between degrees and minutes in latitude and longitude?

• One degree equals 30 minutes.

• One degree equals 60 minutes.

• One degree equals 100 minutes.

• One degree equals 90 minutes.

What is the approximate latitude if a location is halfway between 42 degrees 30 minutes and 43 degrees?

• 42 degrees 15 minutes

• 43 degrees

• 42 degrees 45 minutes

• 42 degrees 30 minutes
