Equator
The equator is an imaginary line that divides the Earth into the Northern Hemisphere and the Southern Hemisphere. It is located at 0 degrees latitude and is the longest line of latitude on the Earth.
Here are some key points to remember about the equator:
- It is an imaginary line that circles the Earth halfway between the North and South Poles.
- It is approximately 24,901 miles (40,075 kilometers) long.
- Areas near the equator generally experience warm temperatures and have a tropical climate.
- The position of the equator affects the length of days and nights throughout the year.
Studying the equator can help us understand the Earth's climate, geography, and the movement of the sun across the sky.

LIFE SCIENCE
From Molecules to Organisms: Structures and Processes
Create representations to explain the unique and diverse life cycles of organisms other than humans (e.g., flowering plants, frogs, butterflies), including commonalities such as birth, growth, reproduction, and death.
Unity and Diversity
Construct an argument from evidence to explain the likelihood of an organism’s ability to survive when compared to the resources in a certain habitat (e.g., freshwater organisms survive well, less well, or not at all in saltwater; desert organisms survive well, less well, or not at all in woodlands).
Create models that illustrate how organisms and their habitats make up a system in which the parts depend on each other.
