| Question | Answer |
|---|---|
| rotation | the spinning motion of an object around its own center or an internal axis |
| day | s the time period of a full rotation of the Earth with respect to the Sun. |
| revolution | a fundamental, non-linear transformation in how scientists understand the natural world. |
| year | the time taken for Earth to complete one full orbit around the Sun |
| season | is a distinct, recurring period of the year characterized by specific climate conditions, weather patterns, and daylight hours, resulting primarily from Earth's tilt and orbit around the Sun. |
| equinox | a scientific, astronomical event that occurs twice a year (around March 20-21 and September 22-23) when the Earth's axis is tilted neither toward nor away from the Sun. |
| solstice | an astronomical event occurring twice annually (June and December) when the Sun reaches its highest or lowest point in the sky at noon, directly overhead the Tropics of Cancer or Capricorn. |
| satellite | any object that orbits—or revolves around—a larger object in space. |
| gravity | a fundamental force of attraction that acts between all objects in the universe that have mass or energy. |
| lunar phases | represent the changing shape of the sunlit portion of the Moon as viewed from Earth. |
| eclipse | a simplified representation of an idea, object, process, or system designed to make complex phenomena easier to understand, visualize, or predict. |
| umbre | a simplified representation of an idea, object, process, or system designed to make complex phenomena easier to understand, visualize, or predict. |
| penumbra | the partially shaded outer region of a shadow cast by an opaque object, where the light source is only partially blocked |
| tide | the regular, alternating rise and fall of Earth's ocean surface, caused by the gravitational pull of the Moon and Sun, combined with Earth's rotation. |
| tidal range | the vertical difference in height between consecutive high tide and low tide levels at a specific location. |
| spring tide | a high-amplitude tide occurring twice monthly during new and full moon phases, when the sun, Earth, and moon are aligned |
| neap tide | a period of moderate tides occurring twice a month, characterized by the smallest tidal range—the lowest high tides and highest low tides. |
