Navigating Latitude and Longitude

This video tutorial introduces the concepts of latitude and longitude, essential for mapping the Earth's surface. It explains the coordinate system used to pinpoint locations, detailing how longitude lines measure east-west distances from the Prime Meridian and affect time zones. Latitude lines measure north-south distances from the Equator, with methods to determine latitude using stars like Polaris. The tutorial emphasizes the importance of understanding these concepts for navigation and communication of specific Earth locations.

Why is a coordinate system necessary in Earth Science?

• To determine the depth of oceans

• To communicate specific points on the Earth's surface

• To measure the height of mountains

• To calculate the distance between planets

What do longitude lines measure?

• Distance north or south of the Equator

• Depth below the Earth's surface

• Distance east or west of the Prime Meridian

• Height above sea level

Where is the Prime Meridian located?

• New York, USA

• Greenwich, England

• Paris, France

• Tokyo, Japan

What is the highest line of longitude called?

• Tropic of Cancer

• Equator

• Prime Meridian

• International Dateline

How much time difference does 15 degrees of longitude create?

• 45 minutes

• 30 minutes

• 1 hour

• 2 hours

What does latitude measure?

• Height above sea level

• Distance north or south of the Equator

• Distance east or west of the Prime Meridian

• Depth below the Earth's surface

What is the latitude of the Equator?

• 0 degrees

• 180 degrees

• 90 degrees south

• 90 degrees north

How can you determine your latitude in the Northern Hemisphere?

• By measuring the altitude of the Sun

• By measuring the altitude of Mars

• By measuring the altitude of Polaris

• By measuring the altitude of the Moon

How do longitude lines appear on a map when viewed from the side?

• Forming concentric circles

• Converging at the poles

• Running horizontally

• Parallel to each other

What happens to your latitude if you travel directly west?

• It increases

• It decreases

• It remains the same

• It fluctuates
