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's surface.
Characteristics of the Equator:
- Location: The equator is located at 0 degrees latitude, halfway between the North Pole and the South Pole.
- Length: The equator is approximately 40,075 kilometers (24,901 miles) long.
- Climate: Areas near the equator experience a tropical climate with consistently warm temperatures throughout the year.
- Day and Night: Near the equator, the length of day and night remains relatively constant throughout the year, with approximately 12 hours of daylight and 12 hours of darkness.
Importance of the Equator:
The equator plays a significant role in the Earth's climate and geography. It affects weather patterns, ocean currents, and the distribution of plant and animal species. The region around the equator is also known for its rich biodiversity.
Study Guide:
Here are some key points to remember about the equator:
- What is the equator?
- Where is the equator located?
- What is the climate like near the equator?
- How does the equator affect day and night?
- What role does the equator play in the Earth's climate and geography?
Understanding the equator is important for grasping concepts related to geography, weather patterns, and the distribution of life on Earth.

Concepts of Life Science (SC1, SC2, SC3)
The student demonstrates an understanding that all organisms are linked to each other and their physical environments through the transfer and transformation of matter and energy by identifying examples of living and non-living things and the relationship between them (e.g., living things need water, herbivores need plants).
The student demonstrates an understanding that all organisms are linked to each other and their physical environments through the transfer and transformation of matter and energy by identifying a simple food chain of familiar plans and animals, diagramming how energy flows through it, and describing the effects of removing one link.
Concepts of Life Science: A student should understand and be able to apply the concepts, models, theories, facts, evidence, systems, and processes of life science. A student who meets the content standard should:
Develop an understanding that all organisms are linked to each other and their physical environments through the transfer and transformation of matter and energy.
