Which of the following statements are correct?
(i) The Prime Meridian passes through Greenwich in the United Kingdom.

(ii) The International Date Line roughly follows 180° longitude but zigzags to avoid land.

(iii) The equator divides the Earth into the Eastern and Western hemisphere.

Correct option is A

The correct answer is (a) Only (i) and (ii) 
Explanation:
· (i) The Prime Meridian passes through Greenwich in the United Kingdom: This statement is correct. The Prime Meridian, designated as 0° longitude, passes through the Royal Observatory in Greenwich, London . It is also known as the Greenwich Meridian.
· (ii) The International Date Line roughly follows 180° longitude but zigzags to avoid land: This statement is correct. The International Date Line (IDL) runs approximately along the 180° meridian but deviates at several points to avoid dividing countries or island groups into different calendar days. These zigzags ensure that politically and economically connected regions maintain a consistent date.
· (iii) The equator divides the Earth into the Eastern and Western hemisphere: This statement is incorrect. The Equator divides the Earth into the Northern and Southern Hemispheres. The Prime Meridian (0° longitude) divides the Earth into the Eastern and Western Hemispheres.
Information Booster:
· Prime Meridian and Time Zones: The Prime Meridian serves as the basis for the world's time zones.  the time at the Prime Meridian is called Greenwich Mean Time (GMT), and global time zones are determined relative to it.
· International Date Line and Date Change: Crossing the International Date Line from east to west means gaining a day, while crossing from west to east means losing a day. The IDL is not fixed by international law, and countries can adjust their alignment.
· Equator and Climate: Regions along the Equator generally experience hot and humid climates with little seasonal variation, characterized by two seasons: a rainy season and a dry season.
