Understanding Latitude and Longitude

The video explains how lines of latitude and longitude form a grid on the Earth's surface, allowing precise location pinpointing. It uses Hawaii as an example to demonstrate how coordinates work. The video also introduces GPS technology, which uses satellites to determine exact locations, and highlights its usefulness for hikers and boaters.

What is the primary benefit of the grid formed by latitude and longitude lines?

• It is used to determine the Earth's age.

• It helps in measuring the Earth's circumference.

• It allows for the precise location of places on Earth.

• It helps in predicting weather patterns.

Which of the following coordinates approximately locate Hawaii?

• 25 degrees north latitude and 150 degrees west longitude

• 10 degrees north latitude and 140 degrees west longitude

• 20 degrees north latitude and 155 degrees west longitude

• 30 degrees north latitude and 160 degrees west longitude

What does a GPS device use to determine your exact location?

• Cell towers

• Weather satellites

• Radio signals

• Satellites in space

Who might find handheld GPS devices particularly useful?

• Pilots and drivers

• Hikers and boaters

• Teachers and students

• Farmers and gardeners

What is the full form of GPS?

• Geographic Positioning Satellite
