art A: Review 1. What is the major line that runs east to west across the globe located at \( 0^{\circ} \) latitude, and divides the Earth into the Northern and Southern Hemispheres? 2. What is the major line that runs north to south in the Atlantic Ocean located at \( 0^{\circ} \) Iongitude and divides the Earth into Eastern and Western Hemispheres? 3. What is the major line that runs north to south in the Pacific Ocean located at \( 180^{\circ} \) Iongitude but zigzags to avoid splitting countries and territories into different calendar days? 3.

The line that runs east to west across the globe at \( 0^{\circ} \) latitude is known as the Equator. It’s like the Earth’s waistline, providing balance and serving as a reference point for measuring latitude. The Equator enjoys a warm tropical climate, making it a habitat for lush rainforests and diverse wildlife! The line that marks \( 0^{\circ} \) longitude in the Atlantic Ocean is called the Prime Meridian. This imaginary line runs through Greenwich, England, and is crucial for navigation and timekeeping. It’s also the starting point for defining time zones, making it a superstar when it comes to global synchronization!
