What does the term 'hemisphere' specifically refer to in geography?

  1. Any landmass on Earth

  2. Half of the Earth, typically divided by the Equator or Prime Meridian

  3. A specific region characterized by unique flora

  4. The top layer of the Earth's atmosphere

The correct answer is: Half of the Earth, typically divided by the Equator or Prime Meridian

The term 'hemisphere' in geography specifically refers to half of the Earth, which can be divided by the Equator into the Northern and Southern Hemispheres, or by the Prime Meridian into the Eastern and Western Hemispheres. The concept of hemispheres is crucial for understanding global geography, climate patterns, and the distribution of flora and fauna. By dividing the Earth in this way, geographers can analyze and compare different regions in terms of their climates, time zones, and ecological characteristics. This division aids in navigation and helps establish a framework for mapping and understanding the planet as a whole.
