Geography Lecture Notes

Introduction

• Exam preparation is important.
• Pay attention to the geography grid.

Longitude and Latitude

• Latitude Lines: Parallel from east to west, parallel to the equator.
• Longitude Lines: Run from north to south.

Grid System

• The network of latitude and longitude lines creates a grid.
• The grid system makes location identification easier.

Important Terms

• Equator: 0° degree, divides the Earth into two parts.
• Prime Meridian: 0° degree, passes through Greenwich.

Time Zones and Standard Time

• India has one standard time zone.
• India's time is determined by comparing it to Greenwich Time Zone.

Longitude and Time

• 360° longitude = 24 hours.
• 15° longitude = 1 hour.
• Add time to the east, subtract to the west.

Imaginary Lines

• All latitude lines are imaginary.
• These lines connect places of equal latitude.

Heat Zones

• Torrid Zone: Between the tropics, the hottest area.
• Temperate Zone: Outside the tropics, less heat.

Great Circle

• Great circle indicates the shortest path.
• Used in navigation and meteorology.

Conclusion

• This lecture focused on the basics of geography.
• More detailed study will be covered in future classes.
