Earth Science Curriculum
GGCA uses a faith-based Bob Jones Space & Earth Science textbook as a structural guide for the 8th grade Earth Science course. This text, along with carefully selected supplementary materials from sources such as NASA, ESA and NOAA, provides an excellent, Biblical framework for studying the Earth and the physical universe in which it resides.
Course outline: 1st Semester: Intro to Astronomy, Sun, Moon 2nd Semester: Solar System, Earth's Atmosphere, Weather, and Water Cycle |
Craters are natural features in terrestrial planet surfaces caused by meteorite impact, explosions, or even activity of volcanoes.
Craters are features common to all terrestrial planets. Terrestrial planets with the most craters lack sufficient mass to keep a thick, protective atmosphere. Earth is not as pock-marked with craters because meteoroids burn up in our thick atmosphere. Without our atmosphere, the surface of Earth would look similar to the barren faces of the moon and Mercury.
