Answer:
Prime meridian - Greenwich
Equator - Great circle
Torrid Zone - Hottest region
Axis - Poles
Step-by-step explanation:
The Prime Meridian is a line, constructed by humans, which is cutting the world into the Western and Eastern Hemisphere. It passes through Greenwich, UK, which is why it is often referred to just as Greenwich. It is used as a zero zone or central zone for time, with every east given a -, while every zone west is given a +.
The Equator is a human-constructed line that cuts Earth into two equal parts, Northern and Southern Hemisphere. It is the line from which latitude is measured, north and south of it, and it is also the line where Earth is the widest.
Torrid Zone is a climatic generalized zone. It is occupying the tropics, thus including tropical rainforests, dry forests, savannas, steppes, and deserts. This zone can be found on five continents, North America, South America, Africa, Asia, and Australia.
The axis is an imaginary line that runs through the poles. It is a line around which Earth rotates. It is tilted by 23.4 degrees (scientifically referred to as obliquity), which has a great influence on Earth's climate.
