The Earth and the Universe
KY Core Content for Assessment: Earth & Space Science -- "The Earth system is in a constant state of change. These changes affect life on Earth in many ways. Understanding the processes that shape the Earth begins with understanding what Earth materials are and what changes occur. In 8th grade, we investigate how these changes occur, so we can be prepared in high school to learn why they occur."
- SC-8-2.3.1 - Students will describe various techniques for estimating geological time (radioactive dating, observing rock sequences, comparing fossils). Techniques used to estimate geological time include using radioactive dating, observing rock sequences and comparing fossils to correlate the rock sequences at various locations. Deductions can be made based on available data and observation of models as to the age of rocks/fossils.
- SC-8-2.3.2 - Students will understand that earthquakes and volcanic eruptions can be observed on a human time scale, but many processes, such as mountain building and plate movements, take place over hundreds of millions of years.
- SC-8-2.3.3 - Students will: - explain the transfer of Earth's internal heat in the mantle (crustal movement, hotspots, geysers); - describe the interacting components (convection currents) within the Earth's system. The outward transfer of Earth's internal heat drives convection circulation in the mantle. This causes the crustal plates to move on the face of the Earth.
- SC-8-2.3.4 - Students will understand that the Sun, Earth and the rest of the solar system formed approximately 4.6 billion years ago.
