What is an Hour?

An hour is a unit of time that is equal to 60 minutes or 3600 seconds. It is commonly used for measuring the duration of events, the passage of time, and for scheduling activities. The concept of an hour originated from ancient civilizations who used sundials to divide the day into 12 equal parts.

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).
