Day
A day is the period of time during which the Earth completes one full rotation on its axis. It is typically defined as the time it takes for the Sun to appear in the same position in the sky, which is about 24 hours. The concept of a day is fundamental to our understanding of time and is used to structure our daily activities and routines.
Key Concepts
- Rotation of the Earth: The Earth spins on its axis, causing day and night as different parts of the planet are exposed to the Sun's light.
- 24-Hour Cycle: A full day consists of 24 hours, with approximately 12 hours of daylight and 12 hours of darkness.
- Measurement of Time: Days are used as a unit of time to organize schedules, calendars, and daily life activities.
Study Guide
Here are some key points to remember and study when learning about days:
- What causes day and night on Earth?
- How is a day measured and divided into hours?
- What are some cultural and religious practices associated with the concept of a day?
- How do different regions of the world experience variations in day length?
- How does the concept of a day impact our daily routines and activities?
Understanding the concept of a day is crucial for comprehending timekeeping, astronomy, and the Earth's relationship to the Sun. It is also essential for daily scheduling and planning.

EARTH AND SPACE SCIENCE
Earth’s Systems
Use evidence to explain how different geologic processes shape Earth’s history over widely varying scales of space and time (e.g., chemical and physical erosion; tectonic plate processes; volcanic eruptions; meteor impacts; regional geographical features, including Alabama fault lines, Rickwood Caverns, and Wetumpka Impact Crater).
Provide evidence from data of the distribution of fossils and rocks, continental shapes, and seafloor structures to explain past plate motions.
Use models to explain how the flow of Earth’s internal energy drives a cycling of matter between Earth’s surface and deep interior causing plate movements (e.g., mid-ocean ridges, ocean trenches, volcanoes, earthquakes, mountains, rift valleys, volcanic islands).
