Rotation
Rotation is the circular movement of an object around an axis. In the context of Earth, rotation refers to the spinning of the Earth on its axis, causing day and night. This concept is essential in understanding various natural phenomena and is an important topic in science.
Key Concepts
- Axis: The imaginary line around which an object rotates.
- Rotation Period: The time it takes for an object to complete one full rotation.
- Effects of Rotation: Rotation causes day and night on Earth, and influences factors such as the Coriolis effect and the apparent path of the Sun and stars in the sky.
Study Guide
Here are some key points to understand and remember about rotation:
- Describe the concept of rotation and its significance in the context of Earth's movement.
- Identify the axis of rotation for the Earth and explain how it influences the length of a day and night.
- Discuss the effects of the Earth's rotation on various natural phenomena, such as the Coriolis effect and the apparent path of the Sun and stars in the sky.
- Compare and contrast the rotation periods of different celestial bodies, such as the Earth, the Moon, and other planets in our solar system.
- Explain how changes in the Earth's rotation could impact life on the planet, including potential effects on the climate and ecosystems.
By understanding the concept of rotation, you will gain insights into the dynamic processes that shape our planet and the broader universe.

Earth/Space Science: Students will use scientific skills and processes to explain the chemical and physical interactions (i.e., natural forces and cycles, transfer of energy) of the environment, Earth, and the universe that occur over time.
Earth History: Explain how sedimentary rock is formed periodically, embedding plant and animal remains and leaving a record of the sequence in which the plants and animals appeared and disappeared.
Explain how sedimentary rock buried deep enough may be reformed by pressure and heat and these reformed rock layers may be forced up again to become land surface and even mountains.
Explain why some fossils found in the top layers of sedimentary rock are older then those found beneath in lower layers: Folding; Breaking; Uplift; Faulting; Tilting.
