Latitude
Latitude is a geographical coordinate that specifies the north-south position of a point on the Earth's surface. It is measured in degrees, minutes, and seconds, with the equator as the starting point (0 degrees latitude). The lines of latitude run parallel to the equator, with the North Pole being at 90 degrees north latitude and the South Pole at 90 degrees south latitude.
Key Concepts:
- Equator: The imaginary line that circles the Earth, dividing it into the Northern Hemisphere and the Southern Hemisphere. It is at 0 degrees latitude.
- Tropic of Cancer: The parallel of latitude located at 23.5 degrees north of the equator.
- Tropic of Capricorn: The parallel of latitude located at 23.5 degrees south of the equator.
- Arctic Circle: The parallel of latitude located at approximately 66.5 degrees north of the equator.
- Antarctic Circle: The parallel of latitude located at approximately 66.5 degrees south of the equator.
Study Guide:
- What is latitude and how is it measured?
- What is the significance of the equator?
- How are the North Pole and the South Pole represented in terms of latitude?
- Identify and describe the Tropic of Cancer and the Tropic of Capricorn.
- Explain the importance of the Arctic Circle and the Antarctic Circle.
Understanding latitude is essential for navigating the Earth's surface and understanding climate patterns. It also plays a crucial role in determining time zones and the length of daylight experienced at different latitudes.

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.
